楼上能不能说的详细些
我把动态生成的代码去了,直接写个函数,这样也不行
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>
<head>
<title> Tree </title> <link rel="StyleSheet" href="js/dtree.css" type="text/css" />
<script type="text/javascript" src="js/dtree.js"> </script>
<script type="text/javascript">
function getnodesmess(){
d1 = new dTree('d1');
d1.add(0,-1,'My example tree');
d1.add(1,0,'Node 1','example01.html');
d1.add(2,0,'Node 2','example01.html');
document.getElementById( "myTree" ).innerHTML =d1;
} </script>
</head>
<body >
<h2>Example </h2>
        <div class="dtree" id="myTree" >
  <script type="text/javascript">getnodesmess(); </script>
</div>
</body>
</html>
看了一下，似乎是dtree有问题，再检查一下
dtree应该没有问题,把生成DTREE的代码直接放入却可以
<div class="dtree" id="myTree" >
<script type="text/javascript">
d1 = new dTree('d1');
d1.add(0,-1,'My example tree');
d1.add(1,0,'Node 1','example01.html');
d1.add(2,0,'Node 2','example01.html');
document.getElementById( "myTree" ).innerHTML =d1;
</script>
</div>
