<template>
  <div>
     <div @click="set()">点击</div>
  </div>
</template>
<script>
window["submitFile"] = val => {
  Platform.selectFile(0)
};
export default {
created(){
  this.set();
},
  methods:{
    set() {
      submitFile()
    },
    getData (){
      Platform.submitFile()
    }
  },
  mounted(){
    window["showContent"] = val => {
      this.getData(val);
    };
  }
};
</script>

第一步：安卓丢一个方法过来，比如说：submitFile，前端就可以这样全局调了window["submitFile"] = val => {
Platform.selectFile(0)
};这个是Platform.selectFile(0)前缀

getdata(){
alter(“调用一个")
}

window["showContent"] = val => {
this.getData(val);
};
