4,196,603 | 4,196,604 | Delete old divs if there are more than 20 | jQuery | <p>I need some help with my jQuery script.
I have a page that refreshes every 10 seconds and new divs from a feed are getting appended at.</p>
<p>My script counts the divs and removes the last div when there are more than 20 divs. This works fine if the feed just appends 1 div at a time. But the feed can also append multiply divs at the same time. When this happens the count can exceed the max of 20 divs. The problem with this is that my script just deletes 1 div and not all the divs that exceed the 20 count.</p>
<p>This is my code:</p>
<pre><code>var $auto_refresh = setInterval(function () {
var $articleCount = $('div').length;
if ($articleCount > 20) {
$('div:last-child').remove();
}
$autoUpdate();
}, 10000); // refresh every 10000 milliseconds for new items
</code></pre>
<p>I need to remove all extra divs so there are always 20 divs. I hope someone can help me out with this.</p>

I want to show 600 characters by default and if show more is clicked it will show 600 more characters and then if clicked again shows 600 more until there are no more characters. I also would like a show less button to collapse the text back to its default 600 characters. I have pages with 5000+ words and this would make reading much easier and make it look nicer. Right now I am using this to show the first 600 chars and when show more is clicked it expands all the way.</p>
<pre><code>$(document).ready(function() {
var showChar = 600;
var ellipsestext = "...";

var h = content.substr(showChar-1, content.length - showChar);
var html = c + '<span class="moreelipses">'+ellipsestext+'</span>&nbsp;<span class="morecontent"><span>' + h + '&nbsp;&nbsp;</span><a rel="nofollow" href="" class="morelink">'+moretext+'</a></span>';

<p>obviously, the code above works but it's not safe. You could potentially add a selector key to the <code>o</code> and get the same result. Is ther a better way of making sure that the object actually is a jQuery object?</p>

<p>So, I can use name, ID or class. Are there other ways? A google search term or a link would be helpful. </p>
<p>EDIT:</p>
<p>I had found the selectors page in the documentation, but didn't think this page applied. I had trouble making sense of the page, and thought that it was referring to something else. That's why I was looking for another search term, because everything was bringing up 'Selectors', and I didn't think that's what I was needing. apparently I was in the right place after all.</p>

First, I get the cumulative height of a series of images. Then I compare this height to the height of their container. If the height of the images is greater, the navigational divs should display.</p>
<p>This almost works, but for some reason, my JS variable 'divheight' isn't gathering the image heights. Can anyone spot my issue?</p>
<p>Note that $count is the number of images, and #th_ will amount to the ID of the final image.</p>
<pre><code><script>
$('#th_<?php echo $count; ?>').ready(function() {
var divheight = 0;
//alert('Number of images: <? echo $count; ?>');
<?php
$msg = '';
for ( $i = 1; $i <= $count; $i++ ) {
?>//alert('Cumulative height of images: 'divheight); <?
//$msg .= 'divheight += parseInt( $("#th_' . $i . '").height() );';
$msg .= 'divheight += parseInt( document.getElementById("th_' . $i . '").height );';// . "\n";
}
echo $msg;
?>
//alert( '<? echo $msg; ?>' );
alert( divheight + ':' + $('#ThumbContainer').height() );
if ( divheight < $('#ThumbContainer').height() ) {
$("#ProdDetailsHoverUp").hide();
$("#ProdDetailsHoverDown").hide();

2,057,304 | 2,057,305 | ASP.net composite control with an attribute that can contain multiple values of an enum type | <p>I'm building a composite control textbox that contains the ability to run some business rule validation on the client (via generic jquery validation methods attached on render) and server side (via C# validation code). I created an enum type with the available business rules that can be validated (denoted with the [flags] attr), but I don't know how to allow the developer enter multiple enum values as an attribute. </p>
<p>For example:
given the enum:
[Flags]
public enum BusinessValidationRules {Logical=0, Theoretical=1, Physical=2, MetaPhysical=4}</p>
<p>I'd like the developer to be able to write a control like this at design time:
<code><cc1:ProofTextBox id="somevalue" validation="Logical&Physical|Theoretical" /></code>
OR, if those bitwise statements are not allowed then I could work with:
<code><cc1:ProofTextBox id="somevalue" validation="Logical,Physical,Theoretical" /></code></p>
<p>Is there a way to do this without using the validation attribute taking in a string and parsing that (i.e. I'd like to get keep it tightly bound to the enumerated type)? </p>
<p>The reason I'd like to do it this way is because I already wrote a generic jquery validator that validates based on enum values and separate code that does the same thing on the server side. I'd like to bake it into the composite control so that future developers don't have to worry about that all. </p>
