Enabling default behaviour link by link with jquery
|
<p>I am an html css design type who is not that comfortable with jquery. I have inherited a site with the link default behaviours disabled with what I can see is this code:</p>
<pre><code>$('a').click(function(event) {
event.preventDefault();
var locationHref = window.location.href;
var elementClick = $(this).attr("href");
var destination = $(elementClick).offset().top;
$("html:not(:animated),body:not(:animated)").animate({ scrollTop: destination}, 1000, function() {
window.location.hash = elementClick
});
return false;
</code></pre>
<p>I need to add normal links to this one page website without messing with this code (it enables parallax scrolling). Is there any way I can do this link by link?</p>
<p>BTW I have seen solutions on here but I must confess to not quite understanding them. Thanks.</p>

clearInterval not working
|
<p>This most likely just a frustration syntax error on my part. But resizeTime just won't clear. The timer just keeps going regardless of using clearInterval on it more than once. Any ideas folks? I have posted my real code:</p>
<pre><code> var resizeTime; // declared outside of wrapper function to INSURE no second declaration will occur
var myTransitionEvent = whichTransitionEvent();
$(window).bind('adapt', function(){
console.log('start', resizeTime);
resizeTime = setInterval(function(){
console.log('go', resizeTime);
methods.relayoutChildren.apply(self);
}, 5);
setTimeout(function(){
console.log('sNend', resizeTime);
clearInterval(resizeTime);
},1000);
});
$('#allies-wrap').bind(myTransitionEvent, function(){
console.log('end', resizeTime);
clearInterval(resizeTime);
methods.relayoutChildren.apply(self);
});
</code></pre>
<p>Here is a sample log from chrome:</p>
<pre><code> start undefined
start 8215
(10) go 8218
start 8218
start 8221
(256) go 8224
(2) sNend 8224
(9) go 8224
sNend 8224
(3) go 8224
sNend 8224
(2596) go 8224
</code></pre>
<p>for those who don't know chrome's log, (2596) means 2596 occurrences of an identical log. </p>

Open Image from assets using external program
|
<p>I've wrote content provider to open a png file in my app package with an external application (standard image viewer of Android). Image is stored in asset folder.</p>
<p>I cannot understand where is a problem, but it doesn't work for me.</p>
<p>openFile of ContentProvider:</p>
<pre><code> @Override
public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException {
URI file_uri = URI.create("file:///data/data/com.package/assets/image.png");
File file = new File(file_uri.getPath());
ParcelFileDescriptor parcel = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
return parcel;
}
</code></pre>
<p>Starting activity:</p>
<pre><code>Uri uri = Uri.parse("file:///android_asset/image.png");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
</code></pre>
<p>Is this approach correct and where is my mistake? Or am I totally wrong?</p>

How can I keep the focus on an input field if the input is incorrect
|
<p>Given the following code:</p>
<pre><code>sPosSelect="#fpJpos input[name=posnum" + iiPos + "]";
if (fIn>fPosMaxWtUse[iiPos]) {
alert(sprintf('%.0f is %.0f more than the position max of %.0f.',fIn,fIn-fPosMaxWtUse[iiPos],fPosMaxWtUse[iiPos]));
$(sPosSelect).val('');
$(sPosSelect).focus();
return;
}
</code></pre>
<p>It works in that I get the alert, and the field is blanked. However, the focus then moves on to the next field when what I want is for it to stay on the field just blanked so the user can try again.</p>
<p>All suggestions are welcome, including anything I'm doing that could be done in a better way.</p>

<p>It is supposed to go return true if I write the password: Abc123, or Abc1A23. But it keep returning to me false value. Even though I tried this peace of code on the web browser. And it works fine.

Expandable Listview image changes on click?

When you use the back arrow the image is indeed back to the closed state even though the group is still expanded. Can anyone shed any light on this?</p>

Python-like decorators in Java?

<p>I spend most of my time programming in Python, so forgive me if my approach to this problem is short-sited:</p>
<p>I want to have certain methods of a class require login credentials. Simply, each method should check whether the class variable <code>user</code> is set, and if so, continue, but if not, spit out a "you need to login" message.</p>
<p>In Python, I would just write a decorator to do this. How can I accomplish the same thing in java with as little redundant code as possible?</p>

});
$(document).on('click','.item', function(){
$(this).remove();
});
});
</code></pre>
<p>This code grabs a user's input, adds it to a list when you click a button, and removes the input from the list when you click on it within the div class item.</p>
<p>How can I make it so that I can return the value of "this"?</p>
<p>For example, if I add the word "test" to the list, and click on it to remove it.... how can grab the value of test from "this"?</p>
<p>Like.. document.write(this) returns [object HTMLDivElement].</p>
<p>I want document.write to return "test" if I click on it in the div.</p>
<p>I can't do document.write(toAdd) because toAdd doesn't exist in the second jquery ("on") function.
Thanks.</p>

implement specific file to a class in android
|
<p>I have developed an application in android. I have a file 'Constants.java' implemented to an activity. This file contains constant values for application. I need to change this constants file according to device resolution.</p>
<p>Is there a way where I can build a preprocessor, where in I can check the resolution of device, and implementa particular file accordingly,
example:
implement constants.java file for 240x320 and implement constants1.java file for 320x480</p>
<p>I tried fetching the integer values from strings.xml file, but it gives me a null pointer exception at <code>Resources res = getResources()</code>, when getResources() is called outside a method.</p>
<p>please help!!</p>

Does jQuery do some magic with the `this` variable?
|
<p>jQuery has gotten us used to the following <code>this</code> pattern:</p>
<pre><code>$(selector).each(function () {
// do something with `this`
// `this` iterates over the DOM elements inside `$(selector)`
});
</code></pre>
<p>According to <a href="http://www.youtube.com/watch?v=ya4UHuXNygM" rel="nofollow">this Crockford talk</a> (about 15 minutes in) the value of <code>this</code> inside a function that is not called with the <code>new</code> operator is the global object, except for ES5 strict mode in which case it is <code>undefined</code>.</p>
<p>Does jQuery do some magic with <code>this</code> to get it to something other than the global object? Please point to specific lines of the source code.</p>

How do I access this variable outside of this jquery loop?
|
<p>I have a simple jquery loop that goes through my form and </p>
<ol>
<li>sees if there is empty fields. </li>
<li>If any are empty, mark them with an 'empty' class and </li>
<li>then create a 'error' variable</li>
</ol>
<p>Basically:</p>
<pre><code>// check all the inputs have a value...
$('input').each(function() {
if($(this).val() == '') {
$(this).addClass('empty');
var error = 1;
}
});
</code></pre>
<p>This works a charm. However, as my code continues, I can't seem to access that 'error' variable... as though it is locked inside the each loop. With the following code being right after the .each() loop, I never get my_error_function() to fire, even though I know that criteria 1 and 2 are working.</p>
<pre><code>if(error == 1) {
my_error_function();
} else {
my_non_error_function();
}
</code></pre>
<p>How do I access this variable so I can use its result elsewhere in the code?</p>

return a single html element with jquery

<p>How can I get jQuery to return a html element exactly the way that <code>getElementById</code> does?</p>
<p>if I <code>console.log($('#container'))</code> I will get : </p>
<pre><code>[<div id="container"></div>]
</code></pre>
<p>But the API I am interacting with obviously doesn't want that (an array) - it wants : </p>
<pre><code><div id="container"></div>
</code></pre>
<p>I know I can achieve this with <code>$('#container').get(0)</code> and a few other ways, It just seems overkill - especially as I'm selecting an ID which will always be unique. </p>

The last obstacle I have is I only want to use <strong>jpg</strong> images for my website but allow users the option of uploading gif, png, or jpg. </p>

Change server IPAdress and perform a redirection automatically
|
<p>I have created an web based application through which the users can change the server (where the web application is hosted) IPAddress.</p>
<p>The problem is that, once i have changed the IPAddress to a new IPAddress, Response.Redirect("MyHome.aspx") is not working any more. I have also tried to redirect the user to the newly updated address but even it doesn't do the trick. No page found message appears after some time.</p>
<p>For example: The url while the web application runs in IIS is : <a href="http://192.168.0.65/WebDemo/Default.aspx" rel="nofollow">http://192.168.0.65/WebDemo/Default.aspx</a> after changing the IPAddress to 192.168.0.66 and redirecting it with the Response.Redirect() method the <a href="http://192.168.0.65" rel="nofollow">http://192.168.0.65</a> is not accessible.</p>
<p>Any idea of achieving this task of changing IPAddress of the server and doing an automatic redirect to the newly assigned IPAddress, will be highly appreciated!</p>

How to display an alert if none of the case statements match?
|
<p>I have a case statement below where it checks for a file type in a file input which works correctly:</p>
<pre><code>function imageValidation(imageuploadform) {
var val = $(imageuploadform).find(".fileImage").val();
switch(val.substring(val.lastIndexOf('.') + 1).toLowerCase()){
case 'gif':
case 'jpg':
case 'jpeg':
case 'pjpeg':
case 'png':
return true;
default:
$(imageuploadform).find(".fileImage").val();
// error message here
alert("To upload an image, please select an Image File");
return false;
}
return false;
}
</code></pre>
<p>Now what happens is that if it matches one of the case statements then it returns true and by default it returns an alert which I want to use if file input is blank.</p>
<p>But how can I display this alert: </p>
<pre><code>alert("Image File Type is Incorrect. Must be either: \n (jpg, jpeg, pjpeg, gif)")
</code></pre>
<p>If the file input does not match with one of the file type cases above?</p>

innerWidth = parseInt(innerWidth) * .01 || .50;
barWidth = parseInt(barWidth) || 267;
// find percentage of total width
var innerWidth = Math.floor(innerWidth * barWidth);
var $innerBar = $('.slider-box div');
$innerBar.css('width', innerWidth + 'px');
console.log("Width should be: " + innerWidth + 'px');
}

<pre><code>$(document).ready(function() {
var $innerBar = $('.slider-box div');
$innerBar.each(function(index) {
var newWidth = $(this).attr("data-bar-width");
barGraph(newWidth, 267);

On 'include' pages, where to call global scripts?
|
<p>I am brand new to PHP and just starting out, so apologies if this is a really dumb question! </p>
<p>I have an index.php page with the following code:</p>
<pre><code><?php include 'includes/header.php'; ?>
<?php include 'includes/repeated-content.php'; ?>
<?php include 'includes/footer.php'; ?>
</code></pre>
<p>I've using the repeated-content.php file as a template, which uses the Supersized plugin for full screen backgrounds... and wish to use this feature elsewhere on the site. What I'm confused about (as I usually use HTML and am only just delving into PHP)... is whether to place all the global JS in index.php (Such as jQuery), and only the Supersized plugin & relevant JS in repeat-content.php or should each PHP page have all the required JS scripts to run such as the jQuery library?</p>
<p>I know it'll work if I do put jQuery on every page (have tested it), but it seems wrong to repeat the HTTP request to reload a library on every include page.</p>

What is the best way to programmatically run javascript when an ASP.net page loads?
|
<p>In my <code>global.asax</code> file for my ASP.net project, I am checking for certain conditions. When those conditions are met, I want to automatically execute javascript code when the page runs.</p>
<p>This is my code:</p>
<blockquote>
<p>if condition Then<br>
Response.Write(" < script type=""text/javascript"" > ")<br>
Response.Write(" // Javascript code to do stuff ")<br>
Response.Write(" < /script > ")<br>
End If</p>
</blockquote>
<p>While this appears to work to execute the Javascript code, I don't think it's a best practice because this code will preceed <em>all</em> of the HTML of the page that gets loaded.</p>
<p>What is the best way of programmatically tacking on some extra Javascript code to be run when my page loads?</p>
<p><b>Update</b> Thanks for the answer. Too bad this solution doesn't work from within <code>global.asax</code>. Is there no way to make this happen site-wide? It seems like <code>global.asax</code> would be the logical place to put code that runs with every page... <code>Response.Write</code> works fine in <code>global.asax</code>.</p>

Using JQuery to set 'dirty' elements back to original values
|
<p>I have a Javascript object that basically represents a Row in an .NET GridView.
When a user clicks on any row in the grid, all the input elements in that row are 'enabled'.(ie 'Edit' mode). </p>
<p>I run this code depending on which row is selected</p>
<pre><code>$(":input", this._row).attr('disabled', true);
or
$(":input", this._row).removeAttr('disabled');
</code></pre>
<p>So far so good. Now, I want to keep track of the values in that row before a user enters the 'Edit Mode', so i can restore the original values if they decide to click out of that row without saving any changes that they made.</p>
<p>So i capture the original values in an array by doing this:</p>
<pre><code>var $inputs = $(":input", this._row);
var values = {};
$inputs.each(function(i, el) { values[el.name] = $(el).val(); });
</code></pre>
<p>the 'values' array now looks like this:</p>
<pre><code>ctl00$ContentPlaceHolder1$resultsGrid$ctl04$COMPONENT1 "56"
ctl00$ContentPlaceHolder1$resultsGrid$ctl04$COMPONENT2 "98"
ctl00$ContentPlaceHolder1$resultsGrid$ctl04$COMPONENT3 "08"
ctl00$ContentPlaceHolder1$resultsGrid$ctl04$COMPONENT4 "200"
</code></pre>
<p>Great so far. The user may then modify these values, but decide not to save the changes.
So i need to restore this row back to it's orignal values from the 'values' array.
Can someone tell me the best way to do this? Im hoping it's something simple, but i'm no jquery expert, yet..</p>
<p>thanks</p>

How does caching work when a javascript file is loaded?
|
<p>I have some tabs that are ajax powered. So everytime a tab is clicked all data is loaded including javascripts. So if they click on say Tab A then click on Tab B and finally Tab A. All Tab A scripts will be loaded twice.</p>
<p>Now I am wondering how does the caching work. On the second time they click on Tab A how much faster will these scripts download? Or will it be as slow as the first time?</p>
<p>Thanks</p>

jQuery - prevent default, then continue default
|
<p>I have a form that, when submitted, I need to do some additional processing before it should submit the form. I can prevent default form submission behavior, then do my additional processing (it's basically calling Google Maps API and adding a few hidden fields to the form) -- and then I need the form to submit.</p>
<p>Is there a way to "prevent default", then some point later "continue default?"</p>

Efficiently read binary data into int[]
|
<p>I have binary data in a file (a list of 32-bit integer values) that I need to get into an int array efficiently. I can't see any way to do this other than loading the data into a byte[] and then converting it into an int[] one element at a time. This is too slow for the amount of data I need to load. It takes about 3 seconds to do the conversion on an actual phone. Reading the data from the file in the byte[] is pretty much instantaneous.</p>
<p>Are there any libraries that use native methods for reading an int[] from a file, or for converting a byte[] to int[]?</p>

Sending emails through SMTP client using current logged in user
|
<p>I have web site set up that has some forms authentication through LDAP. I'm sending an email when the currently logged in user clicks a button, however the email is being sent from my address, and not the user. This creates a bit of confusion.</p>
<p>What I want to do is send emails using the logged users account without having them enter their user information again.</p>
<p>I basically want to do this:</p>
<pre><code> MailMessage message = new MailMessage();
message.From = new MailAddress(User.GetIdentity);
message.Subject = Subject;
message.Body = body;
message.IsBodyHtml = true;
SmtpClient client = new SmtpClient("address.qweqwe", 25);
client.Credentials = new System.Net.NetworkCredential(User.Identity);
client.Send(message);
</code></pre>
<p>Getting the users email isn't a big deal, I've already got methods for that, but I'm not sure how I should go about getting their credentials. They've already logged on to access the page, and I know they have an LDAP email.</p>
<p>Is there any way to do this without forcing the user to log in again just to send the email?</p>

var that = this;
var that2 = last;
setTimeout(function(){
$(that).parent().parent().quickFlipper({refresh :1});
$(that2).parent().parent().quickFlipper({refresh :1});

$('a').removeClass('quickFlipCta');

fadeout and fadein between two different pages in jquery
|
<p>Apologies if this may sounds simple, all im trying to do is fadeout the current page and fadein another page. However I'm having difficulties. I know how to do it between divs, the following fades out the leftcolumn div and inputs this in together with the myform on the stage3.php page. My question is how do i fadeout stage2.php and fadein stage3.php?</p>
<pre><code>$("#leftcolumng").fadeOut(500, function(){
$("#leftcolumng").load('stage3.php #myform', function () {
$(this).fadeIn(50);
</code></pre>
<p>});</p>

any website monitoring library/modules to use in my website?
|
<p>I'm trying to build a site which user can add their websites which should be monitored and can view a detailed report and statistics of it. And also it should be able to monitor local webservices (mainly), </p>
<p>1) is there any popular java library to use for monitoring a website? (in sense to ping a website and load some content etc., or to show whether site is up or not kinda) </p>
<p>2) Also to validate a flow of website (if possible)?<br>
Example: Go to login page, find fields , fill fields and submit form and validate for successful login or not.</p>
<p>I know this kinda looks big but any small part done can be helpful, I've found several of monitoring projects, but they only do normal websites but not local/other webservices and also they can't validate flow of website.</p>

Why are all the iterations run at the same time?
|
<p>Here's the <a href="http://jsfiddle.net/JaQmd/">jsfiddle</a> simulating my problem relating to this code:</p>
<pre><code>$('#button').click(function(){
var i;
for (i = 1; i < 4; ++i) {
$('#img' + i).fadeIn("slow").delay(1000);
$('#img' + i).fadeOut("slow");
}
});
</code></pre>
<p>I was expecting the <code>#img1</code> element to fade in and then for the execution to stop for 1 second and then fade out, then start over for the <code>#img2</code> element etc.</p>

How do you pass a Container.DataItem as a parameter?
|
<p>I'm using a repeater control and I'm trying to pass a parameter as such:</p>
<pre><code><%# SomeFunction( DataBinder.Eval(Container.DataItem, "Id") ) %>
</code></pre>
<p>It's basically calling:</p>
<pre><code>public string SomeFunction(long id) {
return "Hello";
}
</code></pre>
<p>I'm not able to achieve this as I get an error:</p>
<p>error CS1502: The best overloaded method match ... SomeFunction(long id) ... has some invalid arguments.</p>
<p>Any ideas?</p>

Better way to structure/new keyword
|
<p>Some time ago I came across the following construct which I have rarely seen since, though I use it relatively frequently. I use it typically when checking on a whole list of conditions are true and it prevents large levels of indentation. Essentially it uses a for loop to provide a kind of structured goto. My question is firstly whether there is better way to structure this, secondly whether people like it and thirdly whether a new keyword in java/c++ etc. such as unit { } which would only cause breaks to exit to the end of the unit would be useful and clearer. </p>
<p>ps I realise that it is on slip away from an infinite loop, but I think my paranoia about that has meant its never happened.</p>
<p>Edit: I have added some setup code for the further conditions to try to illuminate problems with chained if then elses</p>
<pre><code>boolean valid = false;
// this loop never loops
for (;;)
{
if (!condition1)
break;
condition2.setup();
if (!condition2)
break;
condition3.setup();
if (!condition3)
break;
valid = true;
break;
}
if (valid) dosomething();
</code></pre>
<p>EDIT:</p>
<p>I have just discovered that in fact there is a way to structure this in java without misusing loops etc. and wondered whether this would similarily be frowned on, though I guess I have missed the boat on this one.</p>
<p>The restructured code looks like this.</p>
<pre><code>boolean valid = false;
breakout:
{
if (!condition1)
break breakout;
condition2.setup();
if (!condition2)
break breakout;
condition3.setup();
if (!condition3)
break breakout;
valid = true;
}
if (valid) dosomething();
</code></pre>
<p>Now that removes the misuse of the for loop which caused a lot of the complaints, and is actually a solution I think is quite neat and is what I was looking to find originally.
I am guessing that this structure is probably not well known since no one mentioned it, people object to this as strongly?</p>
