bus.$emit+bus.$on赋值成功取值失败

一、新建bus.js

import Vue from 'vue'
export default new Vue();

二、A页面传值

<script>
import bus from '../../../static/js/bus';
export default {
	data(){
		return{}
	},
	methods:{
		click(row,index){
			setTimeout(()=>{
			          bus.$emit('channel_id',this.row.id);
			  },100);
		}
	}
}
</script>

三、B页面取值

created(){
    bus.$on('channel_id',data=>{
       this.get_channel_id = data;
      console.log("传过来的值"+data);
      console.log("赋值取出"+this.get_channel_id);
     });
      console.log("asasas:"+this.get_channel_id);
},

四、重点

赋值时把bus.$emit()放在setTimeout内
