Hi,
Is there a way to reference a table cell in a table that will have X amount of rows?
I want to use javascript preferably... The only methods I know of are "getElementById" and "getElementByName" - Problem is, since the cells are only known once the page is run, it is impossible to hardcode an Id OR a name before hand.
Any suggestions?
Thanks,
Ash
Jump to PostHi,
here' a simple document that uses HTML DOM manipulation procedure:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="Content-Style-Type" content="text/css"> …
Nevermind, I found the solution:
<html>
<head><title></title></head>
<body>
<script type="text/javascript">
function getRow(t) {
var col=t.cellIndex;
var row=t.parentNode.rowIndex;
var testTable = document.getElementById("testTable");
alert(testTable.rows[row].cells[col].innerHTML);
}
</script>
<table id="testTable" border='1' style="background-color:black; color:white">
<tr>
<td width='150px' onclick="getRow(this)">
test 1
</td>
<td onclick="getRow(this)">
<b>Test B</b>
</td>
</tr>
<tr>
<td width='150px' onclick="getRow(this)">
test 2
</td>
<td onclick="getRow(this)">
<b>Test B</b>
</td>
</tr>
</table>
</body>
</html>My only question now is:
Is there a better way to retrieve cell data than innerHTML ? I tried "data" but it returns "[object]"... When I use innerHTML it returns the html tags, along with the text, and I only want the text...
Thanks.
