EXTJS 4.1 我的面板中有两个锁定网格。 如何在EXTJS 4.1中创建侧面导航栏。有两个选项,一旦点击第一个选项,就会显示第一个锁定网格,单击其他选项时,会创建第二个锁定网格。

我目前的代码是这样的:

    <html>

<script type="text/javascript">

我猜Ext.tab.Panel就是你要找的东西,你的两个网格就是它的项目。您可以使用headerPosition以任意方式对齐选项卡面板标题,或隐藏它并添加自定义工具栏。

作为替代解决方案,您可以使用按钮添加Ext.toolbar.Toolbar并自行添加逻辑。

Simple fiddle说明如何做到这一点,将其作为基础。
