JavaScript和JQuery获取DIV的值

1、设计源代码

<!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" />
<title>JavaScript和JQuery获取DIV的值</title>
<script type="text/javascript" src="jquery-1.11.2.js"></script>
<script type="text/javascript">
     $(function(){
		 $("#jqueryInput").click(function(){
			  var divValue = $("#div_val").text();
			  var divVal = $("#div_val").html();
			  alert("JQuery获取DIV的值:"+divValue+"\n"+divVal);
		 });
	 });
	 
     function javaScriptDiv()
	 {
		 var divVal = document.getElementById("div_val").innerHTML;
		 alert("JavaScript获取DIV的值:"+divVal);
	 }
</script>
</head>

<body>
   <div id="div_val">youhaidong</div>
   <input type="button" value="JavaScript获取DIV的值" onclick="javaScriptDiv()"/>
   <input type="button" value="JQuery获取DIV的值" id="jqueryInput"/>
</body>
</html>

2、执行结果

(1)初始化



(2)点击”JavaScript获取DIV的值“button



(3)点击”JQuery获取DIV的值“button



3、分析说明

(1)JavaScript获取DIV的值

       document.getElementById("div_val").innerHTML;


(2)JQuery获取DIV的值

        a $("#div_val").text();

        b $("#div_val").html();
