Hi,

I've the following html/javascript/css code that I'm trying to execute. But it doesn't work. What I'm trying to do is similar to this: http://jsfiddle.net/FsPSZ/16/ (i've even tried this and the problem is the same)

`

<!DOCTYPE html>
<html>
<head>
<title>test</title>

<style>
#preview{
    position:absolute;
    border:1px solid #ccc;
    background:#333;
    padding:5px;
    display:none;
    color:#fff;
    }
</style>
</head>


<body>
<script>
this.imagePreview = function(){ 
    /* CONFIG */

        xOffset = 10;
        yOffset = 30;

        // these 2 variable determine popup's distance from the cursor
        // you might want to adjust to get the right result

    /* END CONFIG */
    $("a.preview").hover(function(e){
        this.t = this.title;
        this.title = "";    
        var c = (this.t != "") ? "<br/>" + this.t : "";
        $("body").append("<p id='preview'><img src='"+ this.href +"' alt='Image preview' />"+ c +"</p>");                                
        $("#preview")
            .css("top",(e.pageY - xOffset) + "px")
            .css("left",(e.pageX + yOffset) + "px")
            .fadeIn("fast");                        
    },
    function(){
        this.title = this.t;    
        $("#preview").remove();
    }); 
    $("a.preview").mousemove(function(e){
        $("#preview")
            .css("top",(e.pageY - xOffset) + "px")
            .css("left",(e.pageX + yOffset) + "px");
    });         
};


// starting the script on page load
$(document).ready(function(){
    imagePreview();
});
</script>


    <a href="./images/collection/a01.jpg" /*class="preview"*/><img src="./images/collection/a01.jpg" alt="gallery thumbnail" /></a>


</body>

</html>

I have spend many hours trying to figure out the problem but to no vain. I do not know what I am doing wrong.

Your sample code worked for me once I removed the comments on line #60. And of course, I added a reference to a jQuery library in the <head> section.

Ok. I'm new at this. Can you tell me how do I add jQuery reference and do I need to have this jQuery library downloaded somewhere ?

I've tried adding this in the head section but it still doesn't seem to work.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>

Nope, it still doesn't work for me :(

As JorgeM said, you should change this line also:

 <a href="./images/collection/a01.jpg" class="preview"><img src="./images/collection/a01.jpg" alt="gallery thumbnail" /></a>

Everything else in your code works... Once you get the jQuery reference in the head section, even if your path is incorrect on the <a> and <img> elements, you should at least see a broken image icon on the screen and the pop-up when you hover over it.

I can see the image but the pop-up never appears. And once I click on the image being displayed, it shift to the top left corner. The padding or the offset which was there I guess gets removed. The hover image or the hovering effect never appears.

for me the popup appears, only there is no image. Popup with no image appears.

but then I checked the image url- pasted in the addres barr
http://i.imgur.com/XiDtL.jpg

and image is ok.

After that I reexecuted javascript ,and the image was wisible. It was gettgin 403 errors. Not sure why.

Check console - F12 developer tools in chrome. Are you getting more errors?
