cordova - 收到错误消息 "Registering a component with a id (` form 1`) which has already been used"

Question

当我点击同一个按钮超过 1 次时，我收到此错误。这表明什么，我应该采取什么措施来防止它；

[WARN] [WARN][Ext.Component#constructor] Registering a component with a id (`form1`) which has already been used. Please ensure the existing component has been destroyed (`Ext.Component#destroy()`.
2012-05-08 21:29:56.869 ProjectSeal[870:fb03] [WARN] [WARN][Ext.Component#constructor] Registering a component with a id (`new-note-btn1`) which has already been used. Please ensure the existing component has been destroyed (`Ext.Component#destroy()`.

根据错误/警告，我如何销毁组件？

更新

Ext.define('app.view.Contact',{
           extend:'Ext.form.Panel',
           xtype:'contactform',
           id: 'form1',
....

如何让 Sencha 将 id 添加到我的代码中？

更新

[WARN] [DEPRECATE][Anonymous] itemId is deprecated as a property directly on the Component. Please put it inside the config object, and retrieve it using "this.config.itemId"

Answer 1

当用户单击按钮时，您很可能会创建一个窗口或表单对象。在创建过程中，您似乎正在将硬编码的 id 分配给该组件。

您需要确保先前使用的表单已被销毁(例如，检查 closeAction 属性)，或者不要自己分配 id 属性并让 Sencha 执行此操作。
