问题描述

我知道这个问题已经被问了很多次,但是我不能让我的下拉菜单与我迄今为止所做的工作。如果我设置菜单延迟显示,没有setTimeout菜单工作正常,问题出现。任何人都可以看看并提出解决方案吗?我也试图在IE6中工作。




  • 这是setTimeout的完整示例:
    (bugged,not work correct,drop downs stuck stuck,延迟不被识别)


  • 这里是一个没有setTimeout的工作版本




并且这里是一个代码副本:

 <!DOCTYPE html> 
< html class =no-js>
< head>
< meta charset =utf-8>

< style>
body {margin:60px; font-family:sans-serif; font-size:12px;}
ul,ul ul {margin:0; padding:0;}
ul li {
position:relative;
list-style-type:none;
padding:5px 0;
margin:0 10px;
cursor:pointer;
border-bottom:1px solid #ddd;
显示:inline-block;
float:left;
}
.submenu {
background:#eee;
显示:无;
position:absolute;
width:200px;
顶部:25px;
left:0;
margin-left:-5px;
}
.hover {
display:block!important;
}
< / style>
< / head>
< body>

< nav id =navigation>
< ul>
< li class =drop>选项1
< div class =子菜单>
< ul>
< li> Lorem ipsum dolor sit amet,consectetuer adipiscing elit。< / li>
< li> Aliquam tincidunt mauris eu risus。< / li>
< li> Vestibulum auctor dapibus neque。< / li>
< li> Lorem ipsum dolor sit amet,consectetuer adipiscing elit。< / li>
< / ul>
< / div>
< / li>
< li class =drop>选项2
< div class =子菜单>
< ul>
< li> Lorem ipsum dolor sit amet,consectetuer adipiscing elit。< / li>
< li> Aliquam tincidunt mauris eu risus。< / li>
< li> Vestibulum auctor dapibus neque。< / li>
< li> Lorem ipsum dolor sit amet,consectetuer adipiscing elit。< / li>
< / ul>
< / div>
< / li>
< / ul>
< / nav>

< script src =http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js>< / script>

< script>

$(document).ready(function(){

(function(){

var topNav = $('#navigation') ,
drop = topNav.find('。drop'),
myTimer;

drop.hover(function(){
obj = $(this);
subMenu = obj.find('。submenu');
subMenu.addClass('hover');
clearTimeout(myTimer);
},function(){
myTimer = setTimeout(function(){
subMenu.removeClass('hover');
},300);
});

}) );

});



< / script>

< / body>
< / html>


解决方案

我能够解决这个问题。演示此处

  var topNav = $('#navigation'),
drop = topNav.find('。drop'),
myTimer ;

drop.hover(function(){
var obj = $(this);
var subMenu = obj.find('。submenu');
clearTimeout (myTimer);
if(subMenu.hasClass('hover')){
// do nothing
} else {
drop.find('。submenu')。removeClass ('hover');
subMenu.addClass('hover');
}
},function(){
myTimer = setTimeout(function(){
drop.find('。submenu')。removeClass('hover');
},300);
});


I know this questions being asked many times already but I can not make my drop down menu work with what I have so far. The problem appears if I set delay for menu to show, without setTimeout the menu works just fine. Could anyone take a look and suggest the solution please? I am also trying that it works in IE6.

and here is a code copy:

<!DOCTYPE html>
<html class="no-js">
<head>
<meta charset="utf-8">

<style>
    body {margin:60px; font-family: sans-serif; font-size:12px;}
    ul,ul ul {margin:0;padding:0;}
    ul li {
        position:relative;
        list-style-type: none;
        padding:5px 0;
        margin:0 10px;
        cursor:pointer;
        border-bottom:1px solid #ddd;
        display:inline-block;
        float:left;
    }
    .submenu {
        background:#eee;
        display:none;
        position:absolute;
        width:200px;
        top:25px;
        left:0;
        margin-left:-5px;
    }
    .hover {
        display:block !important;
    }
</style>
</head>
<body>

<nav id="navigation">
<ul>
    <li class="drop">Option 1
        <div class="submenu">
            <ul>
                <li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
                <li>Aliquam tincidunt mauris eu risus.</li>
                <li>Vestibulum auctor dapibus neque.</li>
                <li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
            </ul>
        </div>
    </li>
    <li class="drop">Option 2
    <div class="submenu">
            <ul>
                <li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
                <li>Aliquam tincidunt mauris eu risus.</li>
                <li>Vestibulum auctor dapibus neque.</li>
                <li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
            </ul>
        </div>
    </li>
</ul>
</nav>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

<script>

$(document).ready(function(){

    (function(){

        var topNav = $('#navigation'),
            drop = topNav.find('.drop'),
            myTimer;

        drop.hover(function(){
            obj = $(this);
            subMenu = obj.find('.submenu');
            subMenu.addClass('hover');
            clearTimeout(myTimer);
        },function(){
            myTimer = setTimeout(function(){
                subMenu.removeClass('hover');
            },300);
        });

    })();

});



</script>

</body>
</html>
解决方案

I was able to work it out. Demo here http://jsbin.com/owoyon/3/edit

var topNav = $('#navigation'),
    drop = topNav.find('.drop'),
    myTimer;

drop.hover(function () {
    var obj = $(this);
    var subMenu = obj.find('.submenu');
    clearTimeout(myTimer);
    if (subMenu.hasClass('hover')) {
        //do nothing
    } else {
        drop.find('.submenu').removeClass('hover');
        subMenu.addClass('hover');
    }
}, function () {
    myTimer = setTimeout(function () {
        drop.find('.submenu').removeClass('hover');
    }, 300);
});
