子组件里面要用到的两个删除按钮图片

父组件调用方法

<template>
  <el-button type="primary" icon="el-icon-search" onclick="open" size="mini" >打开选人组件</el-button>
    <PeopleSelect ref="peopleSelect" :type="'multiple'" :isCheck="true" :open="peopleOpen" @cancel="peopleOpen=false"   @submit="submitPeople"></PeopleSelect>
</template>

 <script>
 /** 导入选人组件 */
  import PeopleSelect from "@/components/Tools/PeopleSelect/index.vue";


  export default {
    name: "formSetting",
    dicts: ['sys_normal_disable'],
    components:{
     PeopleSelect
    },
    data() {
      return {
       //是否打开选人组件，默认不打开
       peopleOpen:false,
      };
    },
    created() {
     
    },
 
    methods: {
    //打开选人弹窗
       open(){
        this.peopleOpen=true;
       },
      //选择人的确定按钮事件 submitPeople(nikeNamelist)方法传参一个默认接收用户昵称数组   submitPeople(peopleList,nikeNamelist)方法传参两个则是接收用户昵称数组和用户账号数组
      submitPeople(peopleList){
      console.log(peopleList);
        this.peopleOpen=false;
      },
   

  
     
    }
  };
  </script>
  

最终效果如下：
