注意，不應該使用箭頭函數來定義 method 函數 (例如 plus: () => this.a++)。理由是箭頭函數綁定了父級作用域的上下文，所以 this 將不會按照期望指向 Vue 實例，this.a 將是 undefined。

Sorry，我找到問題了，將以下代碼替換
handleClick:??()?=>?{ ????????????????this.content?=?"Suremotoo"; ???}handleClick:?function()?{ ????????????????this.content?=?"Suremotoo"; ????????????}看來不會es6的不要隨便用。
