Check all checkboxes (javascript)
Here is the javascript code for checking all the checkboxes inside an html document.
<script>
function checkAll()
{var inputs = document.getElementsByTagName(’input’);
var checkboxes = [];
for (var i = 0; i < inputs.length; i++) {if (inputs[i].type == ‘checkbox’) {
inputs[i].checked =true;}
}
}</script>

Hi, the code was really helpul. I would like to know something more about this. I am trying to put in code where if I select all the checkboxes the selectall checkbox should automatically get selected.
For eg: I have five rows in a table with check option. I click select all and the above code works. Now can u help me such that when I click each of the checkboxes for these 5 rows the above select all checkbox gets selected. The reverse of what happened with the query. Plz help me out..
