JQuery控制DIV的选取实现方法
我们设置4个div 当鼠标移动到某一个div上面的时候 背景颜色就会发生变化
那我们应该知道要用到mouseover() 和 mouseout() 前一个是移动到某个位置 后面是移开某个位置
还有一个hover(,) 可以替代上面两个方法
1.用mouseover()和mouseout()

<script type="text/javascript" src="jQuery/jquery-1.12.1.js"></script>
<script type="text/javascript">
$(function(){
$("div[id^='div']").mouseover(function() {
$(this).css("background-color","red");
//$(this).css({"background-color":"red"});
});
$("div[id^='div']").mouseout(function() {
$(this).css("background-color","#0FC");
//$(this).css({"background-color":"#0FC"});
});
});
</script>
<style type="text/css">
div[id^="div"]
{
width:300px;
height:500px;
background-color:#0FC;
border:1px solid black;
float:left;
margin-left:2px;
}
</style>
</head>
<body>
<div id="div1"></div>
<div id="div2"></div>
<div id="div3"></div>
<div id="div4"></div>
</body>
</html>
2.hover()
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="jQuery/jquery-1.12.1.js"></script>
<script type="text/javascript">
$(function(){
$("div[id^='div']").hover(function(){
$(this).css("background-color","blue");
},
function(){
$(this).css("background-color","#0FC");
});
});
</script>
<style type="text/css">
div[id^="div"]
{
width:300px;
height:500px;
background-color:#0FC;
border:1px solid black;
float:left;
margin-left:2px;
}
</style>
</head>
<body>
<div id="div1"></div>
<div id="div2"></div>
<div id="div3"></div>
<div id="div4"></div>
</body>
</html>
也可以这么写
$(function(){
var In = function(){
$(this).css("background-color","red");
}
var Out = function(){
$(this).css("background-color","yellow");
}
$("p[id^='p']").hover(In,Out);
}); 相关推荐
