Firefox Document.all equivilant

Firefox Document.all equivilant....

I use getElementById when I know the id, however I need to iterate through all the elements on the page i.e.

for (i=0; i<document.all.length;i++)
{
}

However document.all is proprietry to IE...

How can I perform this same functionality in a W3C standard DOM way??

i would use something like:

var c = document.getElementsByTagName("body")[0].getElementsByTagName("*");

What exactly do you mean by all the elements on the page?

cLFlaVA's method above will expose all the elements within the body tag. If you want to expose other things like embeded styles, code tags, etc, there are other methods for those types.

With cLFlaVA's method above you can test the page elements to see if they have a name or ID attribute like this:

  var c = document.getElementsByTagName("body")[0].getElementsByTagName("*");
  var outstr="";
  for (var x=0;x<c.length;x++) {
    outstr=outstr+"tagName: "+c[x].tagName+", ";
    if (c[x].id)
      outstr=outstr+"ID: "+c[x].id+", ";
    if (c[x].name)
      outstr=outstr+"Name: "+c[x].name+", ";
    if (c[x].type)
      outstr=outstr+"Type: "+c[x].type+", ";
    outstr=outstr+'\r\n';
    }
  alert(outstr);

I just build a string to output in an alert to show all the elements and a few of their attributes. If it has an id, name or type then it is added to the string.
You can just as easily use each test to know the ID or name of the item being accessed though at this point you already have the object reference and can make changes to it directly.

BTW, here is a link to a neat DOM browser that can be useful in determining what can be accessed through the DOM and show what differences in availability there is in various different browsers.
