如何从面板中删除项目 [英] How to remove item from Panel

问题描述

我有容器，其中有框， textfield 和按钮。我在一个面板中添加该容器。当我点击按钮我想删除该容器。问题是，容器已被删除，但没有在UI上显示。

I have container, which have box,textfield and button. I am adding that container in one panel. When I am clicking on button I want to remove that container. Problem is, Container is removed but it not showing on UI.

我的代码是从面板中删除容器。

 var panel = Ext.getCmp("ABC");
 var record = panel.items.items;
 var recordlength = record.length;

 for (var j = 0; j < recordlength - 1; j++) {
    if (record[j].Label == me.Label) {
      record.remove(me);
      panel.remove();
   }
}

推荐答案

你说你可以删除容器，然后尝试这样来更新你的面板。

As you say you are able to remove container then try this to update your panel.

panel.update();
panel.doLayout();

从中删除项目后，将更新您的面板。

It will update your panel after removing item from that.
