Hi am using a button to change the size of a table and I had a few questions about it.

I can change the table width, but then I'm not sure how to chnage it back again to the original state. Is that done with return true/false?

Also, this script is on a page where there is a form, so it in a constant state of refresh, can I use the onload function to keep it's state on reload? I have other reload functions at the bottom of the page too (CngColor & drg), so I'm not sure how to get those to play nice together.

Below is my script:

Thanks.

HTML Code:

<html>
<head>
<script>
function switchheight()
{
document.getElementById('width').width = '200px';
}
</script>
</head>

<body>
<table width="500" id="width">
<tr>
<td bgcolor="green">demo table</td>
</tr>
</table>

<input type="button" value="width" onclick="switchheight()">


<script type="text/javascript">

window.onload=
function 1() {
    var sels = document.getElementsByTagName('select');
    CngColor(sels[0]);
    CngColor2(sels[1]);
    CngColor3(sels[2]);
    CngColor4(sels[3]);
         }

function 2() {
    var wid = document.getElementsById('width');
    switchheight(wid[0]);


    var drg = document.getElementsByTagName('div');
    if(readCookie('wd')) {
        drg[0].style.visibility=readCookie('wd');
        }
};

</script>

</body>
</html>

Hi,usually I use the property “offsetWidth” to get the current width of the table before changing it .and save it to a variable.like this: var theOldWidth=document.getElementById('width').offse tWidth;
