Sir,
Would u please help me to solve my problem?
I am a php programmer.I have set of check boxes with same name and differnt
ids. i used for loop and assigned different names as follows
<input type="Checkbox" id="delete_<?=$row+1?>" name="delete[]"
value="<?=$country_id?>">
I dont want some of them satisfying certain condition and i put in use
instead of the chek box.
I used another check box to select all the check boxes i created in this
way.
Now I want to select all the check boxes if they exist. How i can do it?
Thanks in advance.

In JavaScript, the way to reference an element using its id is this:
document.getElementById('delete_3')
So you could use a for loop like this:
for( var i = 1, j; j = document.getElementById('delete_'+i); i++ ) {
j.checked = true;
}

you cannot. and clientx/y is useless because it does not work cross browser.
you will either have to use a frameset, or abandon the idea.
