EXT PHP 游戏 Ajax 数据结构

控件之间相互调用

比如，有一个grid，上面有一个添加按钮。应该弹出一个window，在window进行保存工作。
点击保存之后，grid要更新。

他们之间的相互调用，难道都是使用getCmp（）作为获取控件的途径吗？

请看是否达到你的要求，且结构清晰

var win;
var addrolewin;
var copywin;
var grid;
var expander;
var ds;

//编辑角色
function actionEditEvent() {
var record = grid.getSelectionModel().getSelected();
if (record) {
win = new Ext.Window({
id:id,
title:"编辑用户组",
iconCls:'edit',

maximizable:true,

modal:true,
html : '<iframe frameborder="0" width="100%" height="100%" src="index.php?mo=groupman&do=editrole&id='+record.data['roles_id']+'"></iframe>'
});
win.on("beforedestroy",function(){
ds.reload();
});
win.show();
}
}

//添加角色

addrolewin = new Ext.Window({
