    <p>I have an application that opens a div with several thumbnails of images. When clicking on an image a new div shall open with the image in full size, and the div shall have the same width and height as the image.</p> <p>From the php file I retrive objects with several parameters, eg. thumbWidth/thumbHeight and width/height. What I need to do is to store the width and height for every image, so that I can open a div with the correct size. What is the best way to do it? I guess I could store width and height in a multi dimensional array, but I guess there is a better way?</p> <p>As you can see in the code below I tried to store eg. this.width in the variable 'imgWidth' and apply it to the event, but every image get the last retrieved width and height so that doesn't work.</p> <pre><code>$.getJSON('...getJSONThumbs.php', function(json) { $.each(json, function() { if (this.thumbWidth &gt; maxWidth){ maxWidth = this.thumbWidth; } if (this.thumbHeight &gt; maxHeight){ maxHeight = this.thumbHeight; } var box = $('&lt;div/&gt;', { 'class': 'imgDiv', 'width': maxWidth, 'height': maxHeight, }).appendTo('.imageArea:last'); var a = $('&lt;a/&gt;', { 'href': '#', }).appendTo(box) var img = $('&lt;img/&gt;', { 'src': 'pics/' + this.fileName, 'width': this.thumbWidth, 'height': this.thumbHeight, }).appendTo(a); imgWidth = this.width; imgHeight = this.height; box.click(function(event) { event.preventDefault(); console(imgWidth + " " + imgHeight); // always the last images width and height $('#desktop').css("background-image", "url(" + img.attr('src') + ")"); }); jQuery(loaderImage).hide(); }); }); </code></pre>

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.
