Ext下tree组件节点名无法显示
<script type="text/javascript">Ext.onReady(function(){var root=new Ext.tree.TreeNode({id:"root",text:"树的根"});var c1=new Ext.tree.TreeNode({text:"子节点1"});var c2=new Ext.tree.AsyncTreeNode({text:"子节点2"});root.appendChild(c1);root.appendChild(c2);var tree=new Ext.tree.TreePanel({renderTo:"hello",root:root,width:300,loader:new Ext.tree.TreeLoader({applyLoader:false,url:"js/treedata.js"})});});</script>treedata.js:[{id:1, text:"子节点"}]
原因：两文件编码不一致
