回复 1***@qq.com: 哦，你用错了，不是这么用的，你看文档，设置focus属性

回复 深海智行:直接设置属性就会 报这个错Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "focus"所以没用

回复 1***@qq.com: 哦，你还是用错了，这样： : focus="focus"
