As Mitch suggests in his comment, you can use Ext.form.Combobox, properly configured, to do this. You won't need to bind anything to the keyup event, as Combobox will handle this for you.
正如米奇在他的评论中所建议的那样，您可以使用正确配置的 Ext.form.Combobox 来执行此操作。您不需要将任何内容绑定到 keyup 事件，因为 Combobox 会为您处理。
Here's the beginning of a config that should work. You'll need to provide an appropariate Ext.data.Store (or subclass thereof), along with a few other config values (displayField,valueField,queryParam, etc). All the necessary stuff is pretty well documented in the API docs)
这是应该可以工作的配置的开始。您需要提供适当的 Ext.data.Store（或其子类），以及一些其他配置值（displayField、valueField、queryParam 等）。所有必要的东西都在 API 文档中得到了很好的记录）
MyTypeahead = new Ext.form.ComboBox({
triggerAction:'all',
typeAhead:true,
mode:'remote',
minChars:2,
forceSelection:true,
hideTrigger:true
});
