GetAttribute not working

[joelwenzel]

I have this code and it is not working. Anyone know why? I'm using ASP.NET and it shows getAttribute as having the following arguments...getAttribute(strAttributeName, [lFlags], AttributeValue) which doesn't make any sense to me. Anyway, here is the code I was trying to use.


<script type="text/javascript" language="JavaScript">
alert( document.getElementById('bgImage1').getAttribute('id'));
</script>

...

<div id="bgImage1" style="position: absolute;width:1000px;height:432px;left:0px;top:50px;">
<img src="Images/bliss top.bmp" alt="" width="100%" height="100%" />
</div>

getAttribute might be an ASP function, but I don't think it's JavaScript.

To get the id (once you have the element), just ask for it by name!

document.getElementById('bgImage1').[red]id[/red]

P.S., if you're using the ID to get the element, though, you probably don't need to get it again!

I realize that about the id. i was doing an example to demonstrat that I can achieve some element. In the example, it should display 'bgImage1'.

Anyway, I think getAttribute is a javascript function. The msdn list it as part of DOM

Maybe it is only in internet explorer though?

What I really need is a way to change the entire style string. I can't do document.GetElementByID('idname').style.[property] = value; because I need to adjust the filter property which isn't listed.

Problem solved. I made the stupid mistakeof using the id of a server element rather then the client id. 'bgImage1' was run at the server.

'glad you figured it out.

Thanks for pointing out the getAttribute function. I've never used it before. I probably won't, still, but it's good to know it's an option!
