hi guys,

help me with this one..

I have a php code to loop a checkbox; 3 checkboxes.

<?php
for($id=1;$id<=3;$id++){
echo "<input type='checkbox' value='$id' id='check_$id' name='checkboxes'/>";
}
?>

Result:
<input type='checkbox' value='1' id='check_1' name='checkboxes'/>
<input type='checkbox' value='2' id='check_2' name='checkboxes'/>
<input type='checkbox' value='3' id='check_3' name='checkboxes'/>

now, i want to create a javascript or jquery codes to get whether the checkboxes are checked using onlick function.

maybe something like this.

my form name is mainform.. if i use getElementById(), then i shud also create a for loop. but i dont want to create a for loop.

i know its easy.. so help me... Beginner!

ReFreezed

With jQuery you could do something like this to see if those three checkboxes are checked:

if ($("[name=[COLOR=#333333]checkboxes[/COLOR]]:checked", document.[COLOR=#333333]mainform[/COLOR]).length == 3)

Without jQuery you'd have to make a loop.

jQuery makes it a lot easier. If you wanted to avoid "direct" loops you'd have to assign a class called, for example, "boxchecked" and do a getElementsByClassName().

Go with refreezed example, it should work perfectly.
