jquery hover事件如何不冒泡
每个div鼠标经过时div背景颜色变化，但不想让镶嵌的div的父div变色，如何做？
听说是什么冒泡事件，不懂。
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
function div_hover(){
$("div").hover(
function(){
$(this).addClass("hover");
},
function(){
$(this).removeClass("hover");
}
);
}
$(function(){
div_hover();
});
</script>
<style type="text/css">
.box1{background:green;width:400px;height:400px;}
.box2{background:yellow;width:300px;height:300px;}
.box3{background:#cc3333;width:200px;height:200px;}
.hover{background:#33cc33}
</style>
<div class="box1">
<div class="box2">
<div class="box3"></div>
</div>
</div>$("div").hover(
function(e){
$(this).addClass("hover");
e.stopPropagation(); //这里
},
function(e){
$(this).removeClass("hover");
e.stopPropagation(); //这里
}
);
e.stopPropagation(); 直接放进去没效果嘛？忘2楼给个运行版看看
结果出来了，很复杂
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
function div_hover(){
var levels = {};
var min = 100, max = 0;
var change = function() {
var q = 0;
for (var p in levels) {
$(levels[p]).removeClass("hover");
q = Math.max(q, p);
}
$(levels[q]).addClass("hover");
};
var getLevel = function(element) {
var level = 0;
for (var parent = element; parent.parentNode; parent = parent.parentNode) level++;
return level;
};
$("div").hover(
function(){
levels[getLevel(this)] = this;
change();
},
function(){
delete levels[getLevel(this)];
$(this).removeClass("hover");
change();
}
);
}
$(function(){
div_hover();
});
</script>
<style type="text/css">
.box1{background:green;width:400px;height:400px;}
.box2{background:yellow;width:300px;height:300px;}
.box3{background:#cc3333;width:200px;height:200px;}
.hover{background:#33cc33}
</style>
<div class="box1">
<div class="box2">
<div class="box3"></div>
</div>
</div>没有使用hover事件，但是效果一样，可以参考

<div class="box1">
<div class="box2">
<div class="box3"></div>
