Question

I have problem with this function. I will explain –
I must execute function if user closes browser. This function is write in JavaScript- saveCookieScriptPrefOnLogOut().

I have this solutions (I writed this using info from StackOverFlow):

var inFormOrLink;
$('a').live('click', function() { inFormOrLink = true; });
$('form').bind('submit', function() { inFormOrLink = true; });

$(window).bind('beforeunload', function(eventObject) {
var returnValue = undefined;
if (! inFormOrLink) {
    saveCookieScriptPrefOnLogOut();
}
saveCookieScriptPrefOnLogOut();
return true;
});

Problems with this solution is: every browser display windows with question “Do you really want to close?”

I have to hide this information/window. Second problem (less important but still) – FF and IE runs this function when I click on Link or form submit. I need to ignore a links and form submit.

solution must be crossbrowser solution (IE, Chrome, FF on windows. The most important is IE). I can use PHP and javascript.

Can you give me any answer how I solve these problems?

Answer 1

Try this:

var inFormOrLink = false;

$('a').live('click', function() { inFormOrLink = true; });
$('form').live('submit', function() { inFormOrLink = true; });

$(window).bind('beforeunload', function() {
    if( !inFormOrLink ) {
        saveCookieScriptPrefOnLogOut();
    }
});

If you return undefined from the event handler (no return statement implicitly returns undefined), the dialog will not appear.. Also, you called saveCookieScriptPrefOnLogOut regardless of inFormOrLink.
