Grid ref as a tooltip 1

[vincelewin]

Can anyone suggest how I can do this.

Currently I am using php with a counter and the while loop to generate a div tag for every 10x10 area and using the alt text for the pop up display.

This is resulting in a slow loading page and a lot of html code.

I thought it would look better and load quicker with a single image and a javascript that would indicate your grid location.

Anyone have an ideas on this?

Thanks for any help

Check out the tooltip section of

http://www.dynamicdrive.com.

They have lots of examples that follow the mouse around, and it should be simple to convert any of them to display the coordinates. After all - the script must have them for the tooltip to follow the mouse around.

Hope this helps,
Dan

Dan,

I did as you suggested and went to dynamicdrives website.

I have downloaded the code below but it has a flaw, this is that when the element you mouse over is a <select><option></option></select> box the div pop up falls under the element.

I have tried adjusting the Z-index on both elements but it makes no difference.

The style section denote the Z-index of 100, just noticed that, but the onmouse over part, at the bottom, defines the size ect of the tip. Its here I added the z-index.

Can you suggest anything?

<style type="text/css">

#fixedtipdiv{
position:absolute;
padding: 2px;
border:1px solid black;
font:normal 12px Verdana;
line-height:18px;
z-index:100;
}

</style>

<script type="text/javascript">

This is a well known issue which you may not be able to overcome entirely, depending on your page structure.

You could try putting your tooltip in an iframe instead of a div, and move that.

Hope this helps,
Dan
