    <p><s>Ok I'm going to run this on the slowest ASP box I've ever seen before, so I'm not looking to use jQuery, I know it would make everything a lot easier but I need to keep my code as small as humanly possible.</s> I'm targeting users with the slowest internet I've ever seen and loading the entire jQuery file will be to much for their internet to take. So I'm not looking to use jQuery for this script.</p> <p>I'm trying to make a script that when the user hovers over the thumbnail the larger image pops up. I'm using the following javascript to achieve this:</p> <pre><code>var hoverImage = document.getElementById("largeImage"); function hoverZoom(selector) { this.node = document.querySelector(selector); if(this.node === null) { console.log("Node not found"); } return this.node.id; } hoverZoom.prototype.show = function(x, y) { var largeImageSrc = this.node.name; hoverImage.style.display = "block"; var largeWidth = hoverImage.offsetWidth; var largeHeight = hoverImage.offsetHeight; hoverImage.style.top = y - (largeHeight / 2) + "px"; hoverImage.style.left = x - (largeWidth / 2) + "px"; hoverImage.style.position = "absolute"; hoverImage.style.background = "url(" + largeImageSrc + ")"; } hoverZoom.prototype.hide = function() { hoverImage.style.display = "none"; } hoverZoom.prototype.checkCoords = function(x, y) { var id = document.getElementById(this.node.id); var elemTop = id.offsetTop; var elemLeft = id.offsetLeft; var elemHeight = id.offsetHeight; var elemWidth = id.offsetWidth; console.log(x + " " + y + " " + this.node.id + " " + id + " " + elemHeight + " " + elemWidth + " " + elemTop + " " + elemLeft); if(x &gt;= elemLeft &amp;&amp; x &lt;= elemLeft + elemWidth &amp;&amp; y &gt;= elemTop &amp;&amp; y &lt;= elemTop + elemHeight) { return true; } } document.body.onmousemove = function(e) { e = e || window.event; while(hoverZoomPI.checkCoords(e.clientX, e.clientY) === true) { var target = e.target || e.srcElement, offsetX = e.clientX, offsetY = e.clientY; return hoverZoomPI.show(offsetX, offsetY); } hoverZoomPI.hide(); } var hoverZoomPI = new hoverZoom(".test"); </code></pre> <p>My problem is that when I hover over another image with the same class name nothing happens. But when I hover over the first image with the class name it works.</p> <p>I've set up a jsFiddle with all my code and an example: <a href="http://jsfiddle.net/f7xqF/" rel="nofollow">http://jsfiddle.net/f7xqF/</a></p> <p>Thanks everybody for their help. I can't say enough about how much you guys have helped me over the last few years. </p>

    3. CO@bfavaretto Loading the entire jQuery file will just make the server seem slower because the client needs to download the file. Our target users are most likely using dial up. So even that file will slow things down

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.
