Question

I have this function:

function block_scroll(key){
    if (key) {
        $(window).bind("scroll", function(){
            $('html, body').animate({scrollTop:0}, 'fast');
        });
    } else {
        $(window).unbind();
    }
}

The first part works as it should, but when I later call block_scroll(false) – it’s still blocking. Wat do?

RE-EDIT
So as suggested I tried…

$(window).unbind("scroll");

…with some confusion. At first it didn’t work – then it worked.

Now I think it failed because I was scrolling the moment block_scroll(false) was called. I’ve tested this several times now. And yes, if I do nothing while the script runs and block_scroll(false) is called – it does work. But it doesn’t if I’m scrolling when it’s called.

Answer 1

$(window).unbind('scroll');

Even though the documentation says it will remove all event handlers if called with no arguments, it is worth giving a try explicitly unbinding it.

Update

It worked if you used single quotes? That doesn’t sound right – as far as I know, JavaScript treats single and double quotes the same (unlike some other languages like PHP and C).
