1,811,634 | 1,811,635 | With two <form>'s on a page, how to you make jQuery only run the functions on one (without using IDs)? | <p>Now I know this sounds elementary, but I honestly can't dial this in. I have two forms on a single page. I wrote some form validating functions that are triggered as such: </p>
<pre><code>$("form").submit(function(event) {
event.preventDefault();
checkRequired();
checkLengths();
checkFormats();
checkErrors();
});
</code></pre>
<p>This is awesome, but inside the functions, I cannot use <code>$(this)</code> to identify the <code><form></code> from which the submit button was clicked.</p>
<p>Let's say I wrote <code>alert($(this).attr('id'));</code> in the <strong>checkRequired()</strong> function. It alerts "<strong>Object, object</strong>".</p>
<p>If I place the same code inside the <code>$("form").submit()</code> function, it returns my form's id.</p>
<p>The selectors inside the functions are things like <code>$("input[type='text']")</code> and similar, but the functions run on all the inputs, not just the ones in the form that was submitted.</p>
<p><strong>Sample function() used:</strong></p>
<pre><code>function checkFormats() {
alert("Checking Formats...");
$(".email").each(function(){
alert("Checking Formats: Email...");
var emailField = $(this).children("input[type='text']");
var strEmail = emailField.val();
if( strEmail.indexOf( "@" ) == -1 ) {
alert("What the hell?");
}
});
}

I need both to work and display different messages for each situation, if BMFNP is checked, INTEF isn't check INTEF and alert it has been added and BMFNP can only do xxxxx. If both are checked, simply alert that BMFNP can only do xxxx, no need to alert it has been added.</p>

5,245,401 | 5,245,402 | Designing full screen graphics for different Android devices | <p>I am a experienced iOS developer but I am totally new to Android. I have to develop a Android app with a full screen background image and various images that has to fit the screen quite well. Now on iOS we live in a "protected" world where this is easy as I know the screen size of every device, but on Android that is very different I think. I have read about the small/normal/large/xlarge and ldpi/mdpi/hdpi/xhdpi structure, but I cant find anything on designing a full screen image that works well across devices with different sizes and ratios. How would I go and do that? I mean, what image size should I make for e.g. a normal+hdpi device to make it look good? The images must not be distorted (so the ratio must not be changed) but I can live with them being shrinked in size. Should I add some "space" to the image in top/bottom or sides to make it work well? How is this done best?</p>

5,298,644 | 5,298,645 | How to display the items from a dictionary in a random order but no two adjacent items being the same | <p>First of all, there is actually more restrictions than stated in the title. Plz readon.</p>
<p>say, i have a <code>dictionary<char,int></code> where key acts as the item, and value means the number of occurrence in the output. (somewhat like weighting but without replacement)
e.g. ('a',2) ('b',3) ('c',1)</p>
<p>a possible output would be 'babcab'</p>
<p>I am thinking of the following way to implement it.</p>
<ol>
<li>build a new list containing (accumulated weightings,char) as its entry.</li>
<li>randomly select an item from the list, </li>
<li>recalculate the accumulated weightings, also set the recent drawn item weighing as 0.</li>
<li>repeat.</li>
</ol>
<p>to some extent there might be a situation like such: 'bacab' is generated, but can do no further (as only 'b' left, but the weighting is set to 0 as no immediate repetition allowed). in this case i discard all the results and start over from the very beginning.</p>
<p>Is there any other good approach?</p>
<p>Also, what if i skip the "set the corresponding weighting to 0" process, instead I reject any infeasible solution. e.g. already i got 'bab'. In the next rng selection i get 'b', then i redo the draw process, until i get something that is not 'b', and then continue. Does this perform better?</p>

5,403,293 | 5,403,294 | C# Variable Getters / Setters | <p>I'm trying to create a simple way for external programs to get/set variables within my class. What I have is a class with several variable such as this:</p>
<pre><code>class myClass
{
public int one
{
get{ /* get code here */ }
set{ /* set code here */ }
}
}
</code></pre>
<p>Rather than just variable 'one' I have close to 100 variables. All are set up the same way with get and set code. What I would like to have is a simple way to get and set the variables. Example: Instead of having to do this:</p>
<pre><code>myClass c = new myClass();
c.one = 5;
</code></pre>
<p>I would like to find a way to do something similar to this:</p>
<pre><code>myClass c = new myClass();
c.setVariable("variableName", value);
</code></pre>
<p>It would be ideal to have the "variableName" text come from an enum list so that they could be referenced like:</p>
<pre><code>c.setVariable(enumName.varName, value);
</code></pre>
<p>I am unsure how to go about this or if it is even possible. As I said i have close to 100 variables which need their own get/set code, but I'd prefer to have only one public get function and one public set function for various reasons.</p>
<p>As I don't think reflection is very efficient, I'd like to avoid it if at all possible.</p>
<p>I've seen other code in C# where something like this is used:</p>

1,544,576 | 1,544,577 | Java Remote File Options | <p>I've recently started an internship and I'm having some issues with Java in the enterprise environment. I've been assigned the task of porting the functionality of an old windows shell script to java so it may be ran on one of our JVMs.</p>
<p>The shell script runs on one of the Windows servers and grabs the previous days log files from a couple of linux boxes then FTPs them to another Windows machine. </p>
<p>I'm not quite sure how to achieve this functionality using java. I only can SSH into the linux boxes. I have got the connection working for the Windows file share, just not sure of the best way to connect to the linux boxes. </p>
<p>I've considered using one of the SSH libraries, but would prefer to avoid using a third party library. </p>
<p>Any insight would be great. Thanks!</p>

953,087 | 953,088 | What's a good way to provide additional decoration/metadata for Python function parameters? | <p>We're considering using Python (IronPython, but I don't think that's relevant) to provide a sort of 'macro' support for another application, which controls a piece of equipment.</p>
<p>We'd like to write fairly simple functions in Python, which take a few arguments - these would be things like times and temperatures and positions. Different functions would take different arguments, and the main application would contain user interface (something like a property grid) which allows the users to provide values for the Python function arguments.</p>
<p>So, for example function1 might take a time and a temperature, and function2 might take a position and a couple of times.</p>
<p>We'd like to be able to dynamically build the user interface from the Python code. Things which are easy to do are to find a list of functions in a module, and (using inspect.getargspec) to get a list of arguments to each function.</p>
<p>However, just a list of argument names is not really enough - ideally we'd like to be able to include some more information about each argument - for instance, it's 'type' (high-level type - time, temperature, etc, not language-level type), and perhaps a 'friendly name' or description.</p>
<p>So, the question is, what are good 'pythonic' ways of adding this sort of information to a function.</p>
<p>The two possibilities I have thought of are:</p>
<ul>
<li><p>Use a strict naming convention for arguments, and then infer stuff about them from their names (fetched using getargspec)</p></li>
<li><p>Invent our own docstring meta-language (could be little more than CSV) and use the docstring for our metadata.</p></li>
</ul>
<p>Because Python seems pretty popular for building scripting into large apps, I imagine this is a solved problem with some common conventions, but I haven't been able to find them.</p>

}

823,467 | 823,468 | Why don't Java LinkedHashMaps have an insert() method? | <p>By <code>insert()</code>, I mean <code>insertBefore(key)</code> or <code>insertAfter(key)</code>.</p>
<p>As far as I can make out, inserting a key in the middle of the map can only be achieved by creating a new map and copying across the existing keys and the new key in the correct order.</p>
<p>Considering that LinkedHashMaps are based on double-linked lists, it would have been trivial to implement <code>insertBefore(key)</code> or <code>insertAfter(key)</code>.</p>
<p>Am I missing something here?</p>
<p><strong>Update</strong>
Thanks to everyone who pointed out the the above methods would break the contract of maintaining insertion order.</p>
<p>So let me rephrase the question: does anyone know of a class that would let me do this?</p>
<p>I looked at <code>SortedMap</code> (and its derivatives, including <code>NavigableMap</code>) but I don't want the map to be explicitly sorted. Think of a <code>nodeList</code> in the browser DOM. I just need to be able to insert elements (in this case KV pairs) in any arbitrary order.</p>
