getElementById not working with Netscape Navigator, HELP!

gchen · Mar 14, 2003

Hi,

I had a problem on below script which works perfect with MSIE but got error on NN saying -- document.getElementById is not a function.

Here is the script, TIA!

<html>
<head>
<title>Resizing</title>
<script language=javascript>

image_now = document.getElementById("image_now&quot

function Larger() {
if (document.getElementById("image_now&quot

.width <=300) {
document.getElementById("image_now&quot

.height *= 1.10;
document.getElementById("image_now&quot

.width *= 1.10;
}
}

function Smaller() {
if (document.getElementById("image_now&quot

.width >=100) {
document.getElementById("image_now&quot

.height *= 0.90;
document.getElementById("image_now&quot

.width *= 0.90;
}
}

</script>
</head>

<body bgcolor="ffffff">
<center>
<form method ="post">
<input type="button" value=" Larger" onclick="javascript:Larger();">
<input type="button" value="Smaller" onclick="javascript:Smaller();">
</form>

<script language=javascript>
document.write("<img src=

id=image_now width=160"+">&quot

;
</script>


</center>
</body>
</html>

gchen:

What version of NN are you using? This works fine on Netscape 6.1..

I guess, you mean Netscape 4.* (Netscape 6.* and 7.* should support it).
Netscape 4.* is too old to know about getElementById. To get a reference to image you do not need to use getElementById at all.
For example, you can use:
document["image_now"].width
instead of:
document.getElementById("image_now&quot.width

However, You will meet another problem. Netscape 4.* does not allow to resize already loaded image.
