请查看此link。将鼠标悬停在“菜单”上,将显示下拉菜单,并暂停。现在,我尝试将菜单更改为TD
元素并将图像指定给此TD
元素,并将鼠标悬停在此图像上时,它将更改图像并显示下拉列表。请参考以下代码:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<style>
li.li_class{
display: block;
}
ul.dropDown{
margin:0px;
padding:0px;
}
#clickable_div {width:166px; background-color:#9c9c9c;display:block;}
#nav_menu{width:166px; height:auto; background-color:#CCC;z-index: 99999; display: none;position: absolute;}
#wrap{ width:166px;}
</style>
</head>
<body>
<table>
<tr>
<td><img src="images/ori_12.png">
</td>
<td id='testable'>
<div id='wrap'>
<img src="images/ori_14.png">
<div id="nav_menu">
<ul class="dropDown">
<li class="li_class"><img src="images/ori_12.png"></li>
<li class="li_class"><img src="images/ori_14.png"></li>
<li class="li_class"><img src="images/ori_15.png"></li>
<li class="li_class"><img src="images/ori_16.png"></li>
</ul>
</div>
</div>
</td>
</tr>
<tr>
<td>
abc
</td>
<td>
def
</td>
</tr>
</table>
</body>
<script>
$('#testable img')
.mouseenter(function () {
this.src = this.src.replace('/ori_', '/hover_');
$('#nav_menu').stop(true, true).slideDown();
})
.mouseleave(function () {
this.src = this.src.replace('/hover_', '/ori_');
$('#nav_menu').stop(true, true).slideUp();
});
$('#nav_menu li img')
.mouseover(function () {
this.src = this.src.replace('/ori_', '/hover_');
})
.mouseout(function () {
this.src = this.src.replace('/hover_', '/ori_');
});
</script>
</html>
当我将鼠标悬停在图片上方时,图片确实会被替换,下拉菜单会向下滑动,但是,我只是无法将鼠标悬停在下拉列表项目上,因为下拉菜单会立即向上滑动。
答案 0 :(得分:1)
尝试
$('#testable #wrap').mouseenter(function (e) {
var anc = $(this).children('img').get(0);
anc.src = anc.src.replace('/ori_', '/hover_');
$('#nav_menu').stop(true, true).slideDown();
}).mouseleave(function (e) {
var anc = $(this).children('img').get(0);
anc.src = anc.src.replace('/hover_', '/ori_');
$('#nav_menu').stop(true, true).slideUp();
});

当您将鼠标悬停在图像上以悬停进入菜单时,会触发mouseout。因此,在包装器上应用悬停事件。如果这个包装器不合适,请创建一个包装器来包装菜单及其图像,并对其应用悬停效果。
