< template >

<div @click="loginFn">aaaa</div>

< / template >

< script >

export default {
  data () {
    return {
    }
  },
  methods: {
    loginFn () {
      // alert(1)
      console.log("hehe")
    }
  },
  mounted () {
    console.log("hehe-mounted")
  }
}

< / script >

there are two problems:
1. Does the event not work?
2. Mounted is not executed? It is executed in the created phase, so why doesn"t mounted execute it?
