Question

I’m currently trying to do a menu with submenu.
Here is what i want to do.

On hover a link (#mylink) i want to display a div (lets call it “#submenu”) right under it.
On mouse leave this link a want to execute a function after 5 second.

In this interval of 5 seconds, if i hover my div (#submenu) i want to clearTimeout.
So this div won’t desapear after 5 seconds.

Here is my code :

$(document).ready(function()
{
    $("#mylink").hover(
        function ()
        {
            $('#submenu').show();
        },
        function()
        {
            var timer = setTimeout(function(){$('#submenu').hide();}, 5000);
        }
    );

    $("#submenu").hover(
        function ()
        {
            clearTimeout(timer);
        },
        function()
        {
            $('#submenu').show();
        }
    );
}

SLaks has the right answer, but to elaborate on it, you would put var timer outside the function handler. Note that this example doesn’t make timer a global variable – it just widens its scope so all handlers can use it.

$(document).ready(function(){
    var timer;
    $("#mylink").hover(
        function(){
            $('#submenu').show();
        }, function(){
            timer = setTimeout(function(){$('#submenu').hide();}, 5000);
        }
    );

    $("#submenu").hover(
        function(){
            clearTimeout(timer);
        }, function(){
            $('#submenu').show();
        }
    );
}
