艹蛋的js错误 头大 prototype的

Question

NewsView.js里有这一段代码
[code="java"]
NewsView.prototype.gridLand = function() {
var sm = new Ext.grid.CheckboxSelectionModel();
var cm = new Ext.grid.ColumnModel({.........
};
[/code]

[code="java"]
Ext.getCmp('NewsView').remove('NewsGrid');
var nv=new NewsView();
var grid=nv.gridLand();
[/code]
在这里调用的时候跑到nv.gridLand时console报错
[color=red][b]Uncaught TypeError: Object [object Object] has no method 'gridLand'[/b][/color]

不解，不解，明明定义了 快来为我解开迷雾吧

Answer 1

[code="java"]
var grid=nv.gridLand();

[/code]

改为

[code="java"]
var grid=nv.gridLand;
[/code]

试试呢，即去掉 ( )
