View Full Version : getAttribute("width") not returning correctly

I'm working on a slider script and it would be just lovely to be able to specify the slider's width in a width attribute on the input that represents it. In the code below, getAttribute("width") is returning 0 in IE, but seems to work fine in firefox. . . .

I think IE will use getAttribute on valid attributes of that element. Since width isn't valid for input its not returning anything. Maybe put it in a title or something.

you may use

getAttributeNode('width').nodeValue

you may use

getAttributeNode('width').nodeValue

I didn't have any luck with this either, I just used a custom attribute name, it'll trip up my validation, but meh. . .;)

Yea... silly IE. To keep the validation, you may set your custom attribute onload with a javascript code using JSON (as the document's elements may be treated as javascript new objects as well).

In you example, you may:

var v=[200,100,300,250,50,500]
onload=function(){
var i=0, e
while(e=document.getElementsByTagName('input')[i++]){
e.customAtt=v[i-1]
}
}


Now the custom attribute is to be found as

object.customAtt
or
object['customAtt']

I'll give that a shot, thanks.
