How do I bind to a table <tr>

Question

When someone double clicks on the entire row, I want an alert. How do I bind a double click to an entire row?

Answer 1

...

$('#table_id tr').dblclick(function(){
  alert('Hello');
});

Note: Using JQuery here, see more info about dblclick here.

Answer 2

Well, without jQuery I suppose you could do something like this:

var rows = document.getElementsByTagName('tr'); // you do mean table rows, right?
var length = rows.length;
for (var i = 0; i < length; i++) {
    rows[i].ondblclick = function(){alert('foo');};
}
