Using Jquery to test checkboxes inside if statement not working

[tshad]

I ran into an issue where I couldn't get my test of a checkbox wouldn't work. Using JQuery inside of an "if" statement seemed to not work but when I took it out of the if statement and put the result into a variable it worked fine.

For example, if I do it the following ways:

if($("input:checkbox").is(":checked") == false)
{
    // Do something if not checked
}

OR

if(!$("input:checkbox").is(":checked"))
{
    // Do something if not checked
}

They don't seem to work. It will always treat it as "true" regardless of whether the checkbox is checked.

But if I do this:

allFilled = $("input:checkbox").is(":checked");

if(!allFilled)
{
    // Do something if not checked
}

It works fine.

Why can't you put the JQuery inside the "if" statement?

Thanks,

Tom

Found it.

IN my code, I had a semicolon right after the if statement and that caused it to always go to the next statement.
