查看MagicSuggest示例，当您单击组件或选项卡进入组件时，组件的样式会发生变化（组件周围的蓝色边框和键盘光标位于输入字段中）。您如何以编程方式将焦点放在 MagicSuggest 组件上？
我已经尝试过$(...).focus()，但这并没有提供相同的行为。一些调试指出我需要触发_onInputFocus事件处理程序，但我不能让它以编程方式触发。Using$(...).find('input[id^="ms-input"]').focus()将焦点放在内部输入字段上，但与用户交互的方式不同（组件没有蓝色边框，键盘光标位于Type or click here“空文本”之后）。
下面的示例演示了尝试以编程方式将焦点放在 MagicSuggest 组件上。单击该OK按钮将清除 MagicSuggest 选择，并将焦点放在 MagicSuggest 组件上。
我做错了什么还是MagicSuggest的限制？如果是后者，纠正它的最佳方法是什么？
