我遇到了一个 ext js 网格的多个实例都显示相同数据的问题。我正在使用 Ext js 4.1.1。
我有一个主标签面板。在该面板中,有多个人员选项卡。每个人选项卡内都有一个详细信息选项卡和一个家庭选项卡。
详细信息选项卡是一个带有文本框、组合框等的简单表单。家庭选项卡具有数据视图和网格。
如果一次只打开一个人选项卡,则一切正常。一旦打开第二个人,家庭选项卡看起来相同(数据视图和网格)。在我看来,这个问题与模型有关。也许他们共享模型的同一个实例,这导致一次刷新就改变了所有数据。数据视图和网格都有相同的问题,但我认为如果我可以解决网格的问题,那么我可以应用相同的逻辑来修复数据视图。除非它变得相关,否则我将把数据视图的代码排除在这个问题之外。
