Question

I have a javascript function for confirmation :

function confirm() {
    var answer = confirm("Are you sure you want to log out?")
    if (answer) {
        return true;
    }

    return false;
} 

and on my link I call this function :

<div class="header">
                <a href="" class="logo"></a>
                <div class="topToolbar">
                    <span><a href="/Logout.aspx" onclick="return confirm();">Log Out</a></span>
                </div>
            </div>

The issue is that it never calls the javascript function, tried to put alerts and didnt get anything.

I even tried to do it with jquery bt still same thing the only difference was that I could get alert on document ready function.

Answer 1

You should rename your function. confirm is reserved for, well, the confirm function:

function shouldContinue() {
    return confirm("Are you sure you want to log out?");
}

and then:

<a href="/Logout.aspx" onclick="return shouldContinue();">Log Out</a>

Actually to be more precise confirm is not a reserved keyword. You could override the confirm function. And that’s what you did. Except that inside this overridden function you called it once again and thus ending in a recursive endless loop.

Here’s an example how you could override it:

window.confirm = function(msg) {
    alert('this is the overriden confirm function');
    return true;
};
