Fade in elements as the cursor moves, without hovering over a specific element

Question

Fade in elements as the cursor moves, without hovering over a specific element

I'm working on implementing a fade-in effect for content when the mouse moves (similar to Google's homepage), but I'd like to avoid this behavior if the cursor is hovering over a specific div.

Here are the basics:

$("html").hover(function() {
    $("#navigation, #content").fadeIn("slow");
});

The above code successfully fades in the content. However, I've been struggling to detect when the cursor is positioned over a particular element. Here's what I've tried:

$("html").one("mousemove", function() {
    if (mouseover == false) {
        $("#navigation, #content").fadeIn("slow");
    }
});

var mouseover = false;
$('#hero').mouseenter(function(){
    mouseover = true;
}).mouseleave(function() {
    mouseover = false;
});

I'm wondering if there's a more efficient way to achieve this effect. Any suggestions?

Answer №1

Consider implementing jQuery's stopPropagation() method within the mousemove handler for your hero element. This will prevent the event from propagating up to the document level, where it could be intercepted by a more generic function.

While I haven't personally tried this solution, my understanding of event bubbling in javascript and the intended functionality of the stopPropagation() method suggests that it should effectively address this issue.

Instead of using $('html'), consider utilizing $(document). Since the element is hidden, you can detect the mouse's x and y coordinates when it hovers over the element. If the mouse's x falls within or equals to the element's x and width plus x, and the same applies for the y coordinate, then display it.

Don't forget to prevent the event from occurring by using unbind().

My code is functioning properly in Firefox:

var overHero = false;
$('#hero').mouseover(function() {
    overHero = true;
}).mouseleave(function(){
    overHero = false;
});

$('html').mousemove( function() {
    if (overHero == false) {
        $("#navigation, #content").fadeIn("slow");
    }
});

However, when I tested it in Chrome, the behavior was different. In Chrome, the #content element fades in immediately regardless of mouse movement. Interestingly, when the mouse is hovering over the #hero element, the fade-in effect does not occur (as expected).
