Question

I have some toy code for a tooltip. It works okay, except that when you mouse into the tooltip it gets hidden with this logic.

I’m banging my head trying to figure out a clean way to get the tooltip to stay visible when you mouse into it, and disappear when you mouse out of both areas. Anyone have a suggestion?

See the example.

HTML

<div id="container">
    <div id="div1"></div>
    <div id="div2"></div>
</div>

Javascript

var div1 = $("#div1");
var div2 = $("#div2").hide();

var hoverTimer;
div1.mouseenter(function(e) {
    var x = e.pageX;
    var y = e.pageY;
    div1.mousemove(function(e) {
        x = e.pageX;
        y = e.pageY;
    });
    hoverTimer = window.setTimeout(function() {
        div2.css("left", x);
        div2.css("top", y);
        div2.show();
    }, 400);
});

div1.mouseleave(function(e) {
    window.clearTimeout(hoverTimer);
    div2.hide();
});

CSS

#container {
    position: relative;
}
#div1 {
    float: left;
    clear: none;
    width: 200px;
    height: 200px;
    background-color: green;
}
#div2 {
    position: absolute;
    width: 100px;
    height: 100px;
    background-color: blue;
}

You create the mousemove event, but aside from setting two variables you never actually move the tooltip. Try this instead. Note I added a 16-pixel “margin” on the mouse position – this is to make it more inline with actual tooltips, and prevents the flickering effect.
