/*
輸入欄位啟用中文輸入法時,將不會觸發 KeyPress 事件,
而 KeyDown 事件中的 KeyCode 則固定傳回 229。
IE9, Firefox 4, Chrome 支援按鍵 Input 事件,
在 IE9 / Firefox4 上可輔助判別中文輸入的細節,
但 IE7 不支援,Chrome 的行為不同。
"input" 事件在输入框「值发生改变时」触发,
比如文本 ("text") 输入框输入或删除文字,
选择 ("select") 输入框值改变等,
但要注意 "input" 事件不能监听复选框 ("checkbox") 选项变化,
要监听复选框选项变化, 要借助 "change" 事件.
"change" 事件, 如上所述, 能够监听复选框选项变化.
此外, "change" 事件亦可监听其他类型输入框输入,
但与 "input" 事件不同, "change" 事件不监听实时输入 (针对文本输入框) ,
只有在输入框「失去焦点时才触发」,
这种行为使 "change" 事件可以实现与 "input" 事件不同的响应需求.
