我想扩展一下TreeLoadee的ProcessResponse方法,用Ext.extend该怎么写

RT，谢谢了

嗯... 写错了.

覆盖默认的就用

[code="java"]
Ext.override(Ext.tree.TreeLoader,{
processResponse : function(response, node, callback, scope){
//do sth
}
})
[/code]

要新的就

[code="java"]
Ext.tree.MyTreeLoader = Ext.extend(Ext.tree.TreeLoader,{
processResponse : function(response, node, callback, scope){
//do sth
}
})
[/code]

[code="java"]
Ext.extend(Ext.tree.TreeLoader,{
processResponse : function(response, node, callback, scope){
//do sth
}
})

[/code]

[quote]Ext.extend(Ext.tree.TreeLoader,{

processResponse : function(response, node, callback, scope){

//do sth

}

}) [/quote]

是不是应该用

Ext.override :wink:
