源代码
Ext.onReady(function(){
var tree = new Ext.tree.TreePanel({
el: 'tree',
loader: new Ext.tree.TreeLoader({dataUrl: 'tree.txt'})
});
var root=new Ext.tree.AsyncTreeNode({
text:'我是根节点'
});
tree.setRootNode(root);
tree.render();
root.expand(true,true);
});
以下是错误提示
http://192.168.1.66/new/ext-2.2/examples/treedemo/tree.txt 405 Method not allowed 14ms
当我改成
var tree = new Ext.tree.TreePanel('tree',{
loader: new Ext.tree.TreeLoader({dataUrl: 'tree.txt'}),
}); 的时候又报以下错误:
this.root is undefined
[Break on this error] Ext.tree.TreePanel=Ext.extend(Ext.Panel,...Ext.reg("treepanel",Ext.tree.TreePanel);
我找不到原因,请高手帮忙,谢谢!!!
确定有这个文件,而且是在同级目录,开始的时候我是直接访问相对路径的.错误之后我就直接访问绝对路径了,但还是出错.路径方面绝对没问题.
