Javascript to check whether a checkbox is being checked or unchecked

Question

I have a javascript routine that is performing actions on a group of checkboxes, but the final action I want to set the clicked checkbox to checked or unchecked based on if

Answer 1

The value attribute of a checkbox is what you set by:

So when someone checks that box, the server receives a variable named test with a value of 1 - what you want to check for is not the value of it (which will never change, whether it is checked or not) but the checked status of the checkbox.

So, if you replace this code:

if (arrChecks[i].value == "on") 
{
    arrChecks[i].checked = 1;
} else {
    arrChecks[i].checked = 0;
}

With this:

arrChecks[i].checked = !arrChecks[i].checked;

It should work. You should use true and false instead of 0 and 1 for this.
