Help with SetTimeout function
I'm in the homestretch of finishing a site which is basically a souped up business advert but I'm having an issue with a set of li links that I am trying to slide left on mouseenter.
The problem is basically, the mouseenter function is way too sensitive. Ive looked into the HoverIntent plugin but I understand it doesn't support mouseenter because mouseenter wasn't a supported jQuery function when the plugin was written. So I've decided to go with SetTimeout function but I cant seem to get it to work properly.
Here's the portion of jQuery I'm trying to implement the SetTimeout function with:
$(document).ready(function() {
$('.home').mouseenter(function(){
$('.home').stop().animate({left:'55%'}, 1000)
$('#icon_home:hidden').delay(600).fadeIn(600);
}).mouseleave(function(){
$('.home').stop().animate({left:'50%'}, 1000)
$('#icon_home').hide();
$('.about').mouseenter(function(){
$('.about').stop().animate({left:'55%'}, 1000)
$('#icon_about:hidden').delay(200).fadeIn(600);
}).mouseleave(function(){
$('.about').stop().animate({left:'50%'}, 1000)
$('#icon_about').hide();
$('.contact').mouseenter(function(){
$('.contact').stop().animate({left:'55%'}, 1000)
$('#icon_contact:hidden').delay(200).fadeIn(600);
}).mouseleave(function(){
$('.contact').stop().animate({left:'50%'}, 1000)
$('#icon_contact').hide();
$('.services').mouseenter(function(){
$('.services').stop().animate({left:'55%'}, 1000)
$('#icon_services:hidden'开发者_StackOverflow社区).delay(200).fadeIn(600);
}).mouseleave(function(){
$('.services').stop().animate({left:'50%'}, 1000)
$('#icon_services').hide();
});
});
});
});
//Hidden icons
$('#icon_home').hide();
$('#icon_about').hide();
$('#icon_contact').hide();
$('#icon_services').hide();
});
html:
<div id="icon_home"><img src="Icons/home.png" width="60" height="60" /></div>
<div id="icon_about"><img src="Icons/about.png" width="60" height="60" /></div>
<div id="icon_contact"><img src="Icons/contact.png" width="60" height="60" /></div>
<div id="icon_services"><img src="Icons/services.png" width="60" height="60" /></div>
<div id="thumb">
<ul>
<li class="home"><a rel="images/gallery/thumb/home.png" src="images/gallery/home.png" a href=" http://gmdcpa.com">
<img src="images/gallery/thumb/home.png" border="0" alt="" /></a></li>
<li class="about"><a rel="images/gallery/thumb/about us.png" src="images/gallery/about us.png" a href="http://gmdcpa.com">
<img src="images/gallery/thumb/about us.png" border="0" alt="" /></a></li>
<li class="contact"><a rel="images/gallery/thumb/Contact Us.png" src="images/gallery/Contact Us.png" a href="http://gmdcpa.com">
<img src="images/gallery/thumb/Contact Us.png" border="0" alt="" /></a></li>
<li class="services"><a rel="images/gallery/thumb/Services.png" src="images/gallery/Services.png" a href="http://gmdcpa.com">
<img src="images/gallery/thumb/Services.png" border="0" alt="" /></a></li>
</ul>
</div>
My question is, should I be combining these into one function? If so, how should I go about doing so and what exactly should I do to implement SetTimeout so animations aren't called by quickly dragging mouse through the mouseenter area? Thanks in advance.
Here it is in one function
var sections = ['home','about','contact','services'];
$.each(sections, function(i,val) {
$('.' + val).mouseenter(function() {
$('.' + val).stop().animate({left:'55%'}, 1000)
$('#icon_' + val + ':hidden').delay(600).fadeIn(600);
}).mouseleave(function(){
$('.' + val).stop().animate({left:'50%'}, 1000)
$('#icon_' + val).hide();
});
And there's a plugin called hoverIntent
to help with incidental mouseenters.
To make it more efficient, you could cache the DOM selections:
$.each(sections, function(i,val) {
var main = $('.' + val);
var icon = $('#icon_' + val);
main.mouseenter(function(){
main.stop().animate({left:'55%'}, 1000)
icon.filter(':hidden').delay(600).fadeIn(600);
}).mouseleave(function(){
main.stop().animate({left:'50%'}, 1000)
icon.hide();
});
Also, if there's only one each of the .home
, .about
, etc, elements, or if there are more, but handler is only intended to affect the one that received the event, then you can replace:
$('.' + val).stop()
with:
$(this).stop()
What you need is a debounce .. take a look at this Remember this will call the handler after a particular timeout...
http://benalman.com/projects/jquery-throttle-debounce-plugin/
Now to make it into a single section, you could define a second class for all say menu
. and use $(".menu").something()
to set the handler.
$(".menu").bind({
mouseenter: $.debounce(250,function() {}),
mouseleave: function() {}
});
If you want the debounce to happen on mouseleave also, you could use
mouseleave: $.debounce(200, function(){})
Remember that you have import the debounce extension for jQuery from that site. debounce is not built in into jquery.
