問題描述
我想我了解小部件定義中 _create 和 _init 之間的區別(例如，請參閱 this question)，但我仍然不確定區分的目的._create() 或 _init() 中有哪些類型的設置任務?如果widget作者選錯了會出現什么問題?
I think I understand the difference between _create and _init in widget definitions (see for instance this question), but I'm still not certain about the purpose for the distinction. What sorts of setup tasks go in _create() or in _init()? What goes wrong if the widget author chooses the wrong one?

使用 _create 構建和注入標記、綁定事件等放置_init() 中的默認功能.對話框小部件，例如，提供 autoOpen 參數表示對話框是否小部件打開后應該打開初始化；一個完美的地方_init()!
Use
_createto build and inject markup, bind events, etc. Place default functionality in_init(). The dialog widget, for example, provides anautoOpenparameter denoting whether or not the dialog should be open once the widget is initialized; a perfect spot for_init()!
還有:
小部件工廠自動觸發_create() 和 _init() 方法在初始化期間，按此順序.乍一看似乎努力是重復的，但有一個兩人的視線差異.因為小部件工廠保護針對多個實例化相同的元素，_create() 將是每次最多調用一次小部件實例，而 _init() 將每次小部件被調用不帶參數調用...
The widget factory automatically fires the
_create()and_init()methods during initialization, in that order. At first glance it appears that the effort is duplicated, but there is a sight difference between the two. Because the widget factory protects against multiple instantiations on the same element,_create()will be called a maximum of one time for each widget instance, whereas_init()will be called each time the widget is called without arguments...
如果作者在 _create() 應該被編碼時使用 _init()，結果將是 _init() 將在每個小部件實例化時執行一次.
If the author uses _init() when _create() should have been coded, the result will be that the code in _init() will be executed once per widget instantiation.
