Thank you for providing the code. I have a doubt, hope you would be kind enough to help me.
I am providing the tooltip in a calendar,which i have written in jsp. This calendar helps the user to select a date and input some description about the date and store in database(MySQL is my database). Once the description in entered and stored in database, i want to show the description as the tooltip.

Is it possible to use the code you have given above for my scenario.

Thanks in Advance

you could hold the description in a HTML hidden form field and that way your JavaScript could access it:

Code:

<input type="hidden" name="desc" />

and in your javascript pass

Code:

document.form.desc.value

to your tooltip function?

can i use the tooltip function that u have given?
Sir, You had provided a code. should it saved as .dhtml file. i had created a hidden texctfield for the description event as you had mentioned.

Code:

<div id="descr" style="visibility:hidden">Enter Description  : <input type="text" name="descText" value=""> </div>

where should i write the mouseover event?

yesm you can use the function i provided.

save it as a .js (javascript) file.

you also need:

Code:

<style type="text/css">
#dhtmltooltip{
position: absolute;
width: 150px;
border: 1px solid black;
padding: 2px;
background-color: blue;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size:9px;
visibility: hidden;
z-index: 100;
/*Remove below line to remove shadow. Below line should always appear last within this CSS*/
filter: progid:DXImageTransform.Microsoft.Shadow(color=gray,direction=135);
}
</style>

then when you want to SHOW the div TEST
