I have an image map on a html page. For each area I have marked as  a hotspot, I would like to have an image appear as a mouseover event. If the onclick event is triggered the link specified must be visited.

Can any Javascript Expert help.

Thank You

Thanks for the quick response

The area parameter that I currently have in one of the areas of the image map is in the form:

<area shape="poly" coords="170,209,198,187,231,188,261,189,270,196,208,247,171,252,150,238,152,224" href="" target="_self" alt="Eastern Cape" />

So I assume that I will include a javascript function call like onclick="showPic(this);" at the end after alt="Eastern Cape"

Could you give me any assistance on how to write showPic(this)

something like:

            function showPic(el, img){
              
            var oDiv = document.getElementById('image');
            if(oDiv == null){
                  oDiv  = document.createElement('div');
                oDiv.id = 'image';
                  oDiv.style.border = '1px solid #000';
                  oDiv.style.background = '#DDD';
                  oDiv.style.position = 'absolute';
                  oDiv.style.padding = '5px';
                  oDiv.style.width = '100px';
            }
            
            oDiv.style.zIndex = '10000';
            oDiv.innerHTML = '<img src='+img+'/> ';
            oDiv.style.visibility = 'visible';

            if (document.all)
              oDiv.style.left=window.event.clientX, oDiv.style.top=window.event.clientY;
                else if (document.layers)
                    oDiv.style.left=e.pageX, oDiv.style.top=e.pageY;
                        
            
            document.body.appendChild(oDiv);
            
            
            }
            
      

      function hidePic() {
            var oDiv = document.getElementById('image');
            oDiv.style.visibility = 'hidden';
      }
            


<div onmouseover="showPic(this, 'test.jpg')" onmouseout="hidePic()">test</div>

Thanks to everybody.

system_down  I have copied your code and have tested it. It shows a popup box but only a placeholder for the image.

I have an imagemap that is broken into areas. I.E.

<area shape="poly" coords="170,209,198,187,231,188,261,189,270,196,208,247,171,252,150,238,152,224" href="" target="_self" alt="Eastern Cape" />

One then for each area.

What I would like is for an image to appear on the onmouseover event whent the cursor passes over this area.

Is this possible?

If I put the function call in the shape, Nohref onmouseover="alert('rect')", a new window is opened

But the following does not generate any popup, namely

Nohref onmouseover="showPic(this, 'pic.jpg')"

Thanks for the help thus far!
