childNodes in Mozilla 1

[EwS]

I need to get the number of rows in my table

allTR = document.getElementById("table").childNodes[0].childNodes;
totalRows = allTR.length;

and, for each row, retrieve

allTR[x].childNodes[col].innerText

totalRows returns the correct number in IE, but in Mozilla, Opera, Netscape, Firefox, and Safari it returns 0. How can I fix it? Thank you!

allTr looks like it returns all of the cells in row 0:

allTR = document.getElementById("table").childNodes[0].childNodes;

Maybe it looks like it, but in IE allTR holds all the rows in the table. How can I do the same in other browsers?

Why that happens... some browsers put textNode objects (node type 3) for every whitespace inside a table, so childNodes[0] returns this node instead of TBODY. IE ignores these nodes, Mozilla doesn't. Because of that it is recommended to use collections tBodies, rows and cols instead of childNodes. For example:

oTab.tBodies[0].rows.length;

This is how I retrieve the value of a particular cell:

oTab.tBodies.rows[0].cells[0].firstChild.nodeValue

How to retrieve the value of the whole row? - Thanks.

This returns value of first element in particular cell.

What is the value of entire row? HTML code? If true, then try .rows[0].innerHTML.

Thank you again.
