退出弹出式重定向，但仅在退出时执行，而不是单击页面上的任何其他html重定向按钮

Question

l am using this code

var exitPop = false;
var nonFire = false;
window.onbeforeunload = function () {
    if(!exitPop){
        exitPop=true;
        return 'Wait! YOU ARE TODAYS WINNER!';
    }
};

setInterval(function(){
    if(exitPop && !nonFire){
        nonFire = true;
        window.location.href = 'http://google.com';
    }
}, 200);

but its also execute on clicking any html redirect button on page.. i want it execute only if someone close browser and it should support all browsers.

i need to add this at only one link in my site how can id do? i mean i am using this code for redirect

<script type="text/javascript"> 

window.fbAsyncInit = function() {
    FB.Event.subscribe('comment.create',
    function (response) {
        window.location = "http://domain.com";
    });
    FB.Event.subscribe('comments.remove',
    function (response) {
        window.location = "http://domain.com";
    });   
};

(function() {
    var e = document.createElement('script');
    e.async = true;
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    document.getElementById('fb-root').appendChild(e);
}());
//]]>
</script>

so i want exit function do not execute for this.. so how do integrate this

Answer 1

I haven't tested it but you should be able to attach a 'click' event to every link on the page, which should set a global variable such as

linkClicked = true;

You can then check that variable in the unload event

if (!linkClicked) // variable is false so they must not have clicked on a link
{
    // Some annoying message here
}

Disclaimer: this is pretty much pseudo code, it's not a copy+paste solution.

Answer 2

window.onbeforeunload does not distinguish between links, back/forward buttons, exit buttons or anything else. If fires when you leave the page, regardless of how you leave the page.
