If mouse over for over 2 seconds then show else don't?


Here is a jQuery slide function I have applied to a div on hover in order to slide a button down.

It works fine except that now everytime someone moves in and out of it, it keeps bobbing up and down.

I figured if I put a one or two second delay timer on it it would make more sense.

How would I modify the function to run the slide down only if the user is on the div for over a second or two?

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js "></script>
<script type="text/javascript">

$("#NewsStrip").hover(
function () {
    $("#SeeAllEvents").slideDown('slow');    },
function () {
    $("#SeeAllEvents").slideUp('slow');
});

</script>

Solution

  • You need to set a timer on mouseover and clear it either when the slide is activated or on mouseout, whichever occurs first:

    var timeoutId;
    $("#NewsStrip").hover(function() {
        if (!timeoutId) {
            timeoutId = window.setTimeout(function() {
                timeoutId = null; // EDIT: added this line
                $("#SeeAllEvents").slideDown('slow');
           }, 2000);
        }
    },
    function () {
        if (timeoutId) {
            window.clearTimeout(timeoutId);
            timeoutId = null;
        }
        else {
           $("#SeeAllEvents").slideUp('slow');
        }
    });
    

    See it in action.
