event bus
bugevents.js

import Vue from "vue"

export default new Vue;

rm1.vue

<el-button type="text" @click="sendToken">
      
</el-button>
------------
import bug from "../../../../static/js/bugevents.js";
data(){
        list: {
            token:1
        }
     
},
methods:{
       sendToken(){
        var token = this.list.token;        
        bug.$emit("usertoken",token)
      }
}

rm2.vue

<el-input v-model="token"></el-input>
----------
import bug from "../../../../static/js/bugevents.js";
data(){
    token:""
},
mounted(){
      //rm1
      var self=this;
      bug.$on("usertoken",function(token){
          self.token=token;//datatoken
       })
}

a method error or a code error? I hope all the great gods will give me some advice

What's wrong with

sendToken () should be written in methods

found the problem,

mounted(){
      //rm1
      var self=this;
      bug.$on("usertoken",function(token){
          self.token=token; 
          //console.log(self.token),
       })
}

The

value has been taken, but in

bug.$on("usertoken",function(token){
     self.token=token;
 })

cannot be taken out and cannot be assigned to the form,
in data. How to solve this problem?
