Javascript 与jquery 互转
jquery 为<script src="jquery-1.8.3.js"></script>
<script type="text/javascript">
$(function () {
$("input").click(function () {
var a= $("#shang ul li span");
var b = a.get(0); //jq 对象转 js 对象
b.innerHTML = "张三";
var c = $(b); //js 对象转 jq对象
c.css("background-color", "green");
});
});
</script>
</head>
<body>
<input type="button" value="dianji"/>
<div id="shang">dddds
<ul>
<li>fasl</li>
<li> sssss<span> span hong</span></li>
</ul>
</div>
</body>
