GetAttribute With "this"
Jul 2, 2002
i make function like this:
function chrCount(which){
maxChr = document.getElementById(which.name).getAttribute('maxlength');
if (which.value.length > maxChr)
which.value = which.value.substring( 0 , maxChr )
else
document.getElementById('chrLeft').innerHTML = maxChr-which.value.length + " chr(s)Left" ;
}
html code:
<input name="name" type="text" maxlength="8" onKeyDown="chrCount(this)" onKeyUp="chrCount(this)">
<div id="chrLeft" ></div>
above code work in IE6, not in Mozilla, can anybody tell the right code ? running in IE6 and DOM browser only is find.

I have the following code which is working in Firefox:
function showOptions() {
if(!document.getElementById) return false;
if(!document.getElementsByTagName) return false;
var lnks = document.getElementsByTagName("a");
for(var i=0; i<lnks.length; i++) {
alert(lnks[i].getAttribute("class"));
if(lnks[i].getAttribute("class") == "toggle") {
lnks[i].onclick = function() {
var options = document.getElementById("multiretailers");
options.style.display="block";
}}}}
I understand that IE doesn't like he getAttribute() method and is
returning null for the class name.
What are the work arounds for this?

I'm trying to get the value of an object's property. getAttribute returns "null" even though I'm sure the property is set. I can easily set the property, and in my actual script I do so dynamically. I just want to read the property and can't.
To help explain my problem, I've attached an example .html file as a .txt file.
The critical part of the code is this section that is based on "textbook" examples of how to get an attribute:
<script type="text/javascript">
function
showcolor() {
var myobject = document.getElementById("lab");
var myproperty = myobject.getAttribute("color");
alert(myproperty);
}
</script>
This is called via a button on the bottom of the page. The DIV object with the ID "lab" exists and has a color attribute defined in CSS, but I cannot read it, nor any other attribute, with a script. The alert displays "null".

I'm 2 for 2 on stupid questions this works in FireFox but not in IE it's not returning the value of the style element and I'm getting [object] error??
document.getElementById('test').innerHTML = document.getElementById('id_CompanyName').getAttri bute('style');
<div class="dR4C2">
<p id="id_CompanyName" style="font-size:<%=aspNameFontSize%>px;">
<%=aspCompanyName%>
</p>
</div>
It seems to be a problem with the getAttribute('style') portion of the code because if I change the request to getAttribute('id') it executes properly....

During development of Bing Maps, I've come across a problem when reading in an XML file and plotting a ploygon. The code works fine on IE, but FireFox is giving me the following error message: Error: xNodes[i].getAttribute is not a function
The function in its entirety is copied below and the problem line is marked in red. Hoping that someone may have come across this problem?

I am trying to get a url attribute from an xml node:
<item>
<media url="http://blablabla.com" />
</item>
I can do this in IE with the following code:
var newDom = xmlhttp.responseXML;
var x = newDom.getElementsByTagName("item");
var urlNode = x[0].getElementsByTagName('media');
var myUrl = urlNode[0].getAttribute('url');
If I try this code in FireFox it gives me the following error:
urlNode[0] has no properties referring to this line : myUrl =
urlNode[0].getAttribute('url');
