    <p>I'm using jquery and i'm trying to create a slideshow.</p> <p><strong>Before i append the image</strong>, i shall know <strong>the Width of the image</strong>. So i use <em>.width()</em> of jquery and <em>.attr("width").</em></p> <p>My <strong>code</strong> is as follows:</p> <pre><code>var attr_href = $next.attr('href'); /*returns the href of the image*/ var $item = $('&lt;img src="'+attr_href+'" /&gt;'); //$item contains the image, the image is not displayed to the browser yet!!! var itemWidth = $item.width(); alert(itemWidth); // ---&gt; returns zero 0 in Mozilla and in IE var itemWidth2 = $item.attr("width"); alert(itemWidth2); //In Mozilla, the first time it returns 0.After the image is loaded, it returns the right Width //In IE, always returns 0 zero !!! //Now i have to append the photo and i have to use the right Width of the image!!! var final_img = $('&lt;img src="'+attr_href+'" width="'+itemWidth+'"/&gt;'); $('.SlideShow').append(final_img); </code></pre> <p>So, i tried to use the <strong>.load()</strong> and i did:</p> <pre><code>var attr_href = $next.attr('href'); /*returns the href of the image*/ var $item = $('&lt;img src="'+attr_href+'" /&gt;'); //$item contains the image, the image is not displayed to the browser yet!!! $item.load(function () { var WidthAfterLoading = $item.attr("width"); var WidthAfterLoading2 = $item.width(); }); alert(WidthAfterLoading); //returns "undefined" in both IE and Mozilla alert(WidthAfterLoading2); //returns "undefined" in both IE and Mozilla </code></pre> <p>So, before i append the image to the browser, i shall know the right width of the image. But i get zero(0) and undefined.</p> <p>Is there any other way, in order to take the <strong>right width of the image??</strong></p> <p>Thanks, in advance</p>

    3. COI apologize, I was thinking that `$item` was the `a` tag.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
