Javascript Gurus...need assistance with IE 6 and IE 7 browser

[2levelsabove]

IE 6 and IE 7 are throwing errors at me. The JS error I get is
'elements[...].value' is null or Not an object

Code:0

What could it be ? Please help me

var bform = document.forms['billing'];

var postStr = window.location.search.substring(1);

 for (var m in bform.elements) {
 if ((bform.elements[m].value != null) && (bform.elements[m].value != null))
  {postStr += "&" + bform.elements[m].name + "=" + escape(bform.elements[m].value);
                                                                     
             
                                }
     
                                req.send(postStr);

Does

var m in bform.elements

provide you with an element object, or the index of an existing element?

element object I believe.

I am so lost on this one

 

[trollacious]

Well, then test it to make sure. If it's the element object, you have an obvious error using

bform.elements[m]

You write the code, you test it to see what it's producing.

DO you have any JS frameworks in play that you've not mentioned (such as Prototype, JQuery, etc)? Some of these modify the DOM so that the "in" syntax you're using gives you much more that you think.

If so, use a regular "for" loop instead.

Hope this helps,

Yes thankyou so much for asking

The for had some issues involved


I did:
///////////////////////////////////////////////////
var postStr = window.location.search.substring(1);
for(i=0; i<document.forms["billing"].elements.length; i++)
{
//alert("The field name is: " + document.forms["billing"].elements.name + " and it’s value is: " + document.forms["billing"].elements.value + ".<br />");

postStr += "&" + document.forms["billing"].elements.name + "=" + escape(document.forms["billing"].elements.value);
}
///////////////////////////////////////////////////


and it seemed to work fine.


Thanks again
