Get the number of rows in a HTML table [duplicate]

Question

I've browsed the Internet looking for an answer on this but I can't find a solution. I want to count the amount of rows my HTML table has in when a link button is pressed. Can someone help me out please?

This is what I have so far:

 $('#HypSelectAll').click(function () {      var count = $('#gvPerformanceResult').children().length;      for (i = 0; i < count; i++) {         alert(i);      }  }); 

But some reason it returns 0 even though I have about 12 rows in my table? I've checked my ID name and it's correct.

Answer 1

var x = document.getElementById("myTable").rows.length;
