Javascript get cells of a table row TR

rated 0 times [ 98] [ 3] / answers: 1 / hits: 65477 / 13 Years ago, mon, april 11, 2011, 12:00:00

I want to manipulate table cells with javascript, and so far I managed to get into tr-s, by using:

var as = document.getElementById('answers['+id+']');

var trs = as.getElementsByTagName(tr);

for (var i in trs)

{ ... }

UPDATE: The as variable contains a reference to the table.

Inside of the for cycle I wanted to go on the same login line and I have tried:

var tds = trs[i].getElementByTagName(td);

The problem is that on debugging I get the following error:

Uncaught TypeError: Object #<HTMLTableRowElement> has no method 'getElementByTagName' .

How could I get into the td-s of the tr-s?

its getElementsByTagName and not getElementByTagName

var as = document.getElementById('answers['+id+']');

for(var i=0;i<as.rows.length;i++) {

    var trs = as.getElementsByTagName(tr)[i];

    var cellVal=trs.cells[0]

}

the variable cellVal will give the reference to the first cell or <td> similarly do for all the cells by increasing the index or putting it in a loop would make it dynamic...
