<p>The 'data-height' is 108px but it's setting the height of the DIV to 360px. The DIVs with content in work fine, it sets the correct height but seems to come to the wrong calculation on DIVs with no content in.</p>
<p>This is basically the jist of the code.</p>
<p>Set the hight as a value on the div.</p>
<pre><code>$(".articleSlide").each(function () {
var current = $(this);
current.attr("data-height", current.height());

<p><strong>@ Giovanni Galbo</strong> : yes and no. The code is dealing with the programming of the flash memory in an external device, and logically represents a single byte of memory. I could cast it later, but this seemed more obvious. I guess my C heritage is showing through too much!</p>
<p><strong>@ Jonathon Holland</strong> : the 'as' syntax looks neater but unfortunately doesn't appear to work ... it produces:

1,288,602 | 1,288,603 | jquery disable parts of page | <p>I am displaying a modeless jquery dialog on top of a page. When the dialog is displayed I wish to only allow the user to interact with a certain portion of the page (mainly because I do not want them naving away or clicking other controls that cause postbacks). I thought it would work well to use the same mechanism that jquery uses with a modal dialog except instead of disabling the entire page, disable all but the portion I wish to remain active. Does someone know how jquery modal dialog does this or have a better suggestion?</p>

<p>In my localhost, such functions only work if my <code>setlocale()</code> value is <code>en_GB</code>. However, on my live server the same functions will only work if <code>setlocale()</code> is set to <code>en_GB.UTF8</code>.</p>
<p>So my question is: what causes the different requirements? As presently my configuration file has a dirty <code>if/else</code> statement to find what server it's being ran on and dynamically specifies the <code>setlocale()</code> value.</p>
