Javascript: InnerHTML Issues

[Tanner8]

Hey, well I wrote a script to keep adding rows onto a table. That works, and all the fields work, the problem is extraction of data.

I have drop down menu's and such in each row, but they all turn out to have the same name because to add them, I am just using innerHtml and sticking in the code. The problem I have is that I can't figure out how to get the data of one of those dropdown menus in a specific row.

I tried something like this,

var x=document.getElementById('info').rows[0].cells;
var y=x[2].innerHTML.value;

and a bunch of other stuff along those lines, but none worked.

Any ideas?

Thanks.

Both innerHTML and value are properties, therefore there is no such thing as innerHTML.value, nor could there be value.innerHTML.

If you want to get child elements of a node you will have to use childNodes and nextSibling.

Can't figure this out, can you give an example or suggestion please?

Thanks

A poor solution would look something like this:

theCell = document.ge.t....rows[0].cells[2];
for (i = 0; i < theCell.childNodes.count; i++) {
  if (theCell.childNodes[i].nodeName == 'SELECT') {
    return theCell.childNodes[i].value;
  }
}

Anything I do gets me undefined. Just trying to count the childnodes is undefined for me.

var x=document.getElementById('info').rows[0].cells[2];
alert(x.childNodes.count)//Undefined

Thanks

1) What browser are you using
2) Does x have a value [alert(x)]
In fact, you might want to try this:

var x = document.getElementById('info');
alert(x);
x = x.rows[0];
alert(x);
x = x.cells[2];
alert(x);
x = x.childNodes;
alert(x);
x = x.count;
alert(x);

This is all in firefox. Here is what is returned at each one of those steps.

[object HTMLTableElement]
[object HTMLRowElement]
[object HTMLTableCellElement]
[Object NodeList]
undefined

And that'd be because I've got the wrong property. Javascript uses length rather than count.
I think the rest of it should work...

I missed that as well. Sometimes the most obvious things are the hardest to find. Anyway, works great now, thanks for your help!
