往WINDOWS里面添加表格。只有第一次打开的时侯能显示。

var xxx=new com.wutai.gridpanel
items:[
{
layout : "column",
items : [{ columnWidth:.50,
layout:"form",
items:[getgoodsgrid,notloadgrid]
},{ columnWidth:.50,
layout:"form",
items:[loadinggrid,goodslist]
}
]
}
]
});

xxx.show();
xxx.items.items[0].items.items[0].remove(xxx.items.items[0].items.items[0].items.items[1]);
xxx.items.items[0].items.items[0].add(shortnotloadgrid);
xxx.items.items[0].items.items[0].doLayout();
为什么只能显示一次。关掉一掉。再打开添加的这个表格就不显示了。
[b]问题补充：[/b]
closeaction是HIDE
REMOVE是把那个表格去掉换上新的表格。
[b]问题补充：[/b]
第一次显示。关了以后再开就不显示了。

第一那个EXT。GETCMP（“SHOWWIN”）是从哪来的。。。
第一个变量WIND的作用是什么。您的代码好像运行不了。

修改了一下.忘记你说的窗口关闭后再打开的问题了
[code="js"]

Ext.onReady(function() {
var wind;
Ext.get('showWin').on('click',function(){
if(!wind){
var myData = [

store.loadData(myData);

wind.show();

});[/code]

xxx.items.items[0].items.items[0].remove(xxx.items.items[0].items.items[0].items.items[1]);
xxx.items.items[0].items.items[0].add(shortnotloadgrid);
xxx.items.items[0].items.items[0].doLayout();

你这个是在做什么/
你说的windows关闭后是destory了还是hide了.你可以设定widows的配置选项closeAction:'hide',这样当你关闭window的时候,他只是隐藏了.而不会去销毁对象.这样你再显示就不会有问题.你最好不要去remove什么的.

你的意思是新添加进去的grid不显示咯?

[code="js"]
xxx.items.items[0].items.items[0].remove(xxx.items.items[0].items.items[0].items.items[1]);
//你这里就是想把items.items[0].items.items[0]里面的去掉,如果里面只有一个对象的话,你可以用removeAt(0);就可以了
xxx.items.items[0].items.items[0].add(shortnotloadgrid);
xxx.items.items[0].items.items[0].doLayout();
[/code]
我待会做一个示例看看,给你
