I always run into this little problem - how to check all and uncheck all checkboxes no a single page. Heres a nice easy solution.
CODE:
-
function checkAll()
-
{
-
if(document.getElementById('checkallbox').checked == true) // the element that you will check to check all boxes.
-
{
-
var checks = document.getElementsByName('CHECKBOXNAME');
-
for(var i=0;i<checks.length;i++)
-
{
-
checks[i].checked = true;
-
}
-
}
-
else
-
{
-
var checks = document.getElementsByName('CHECKBOXNAME');
-
for(var i=0;i<checks.length;i++)
-
{
-
checks[i].checked = false;
-
}
-
}
-
}
Enjoy!
