vue实现全选组件封装实例详解

效果

封装的组件

<template>
  <el-form-item :label="label">
    <el-checkbox :indeterminate="isIndeterminateBool" v-model="checkAll"
                 @change="handleCheckAllChange">全选
    </el-checkbox>
    <el-checkbox-group v-model="checkList" @change="handleCheckedCitiesChange">

      <el-checkbox :label="key" v-for="(item,key) in this.channelList"
                   :key="key">{{ item }}
      </el-checkbox>
    </el-checkbox-group>
  </el-form-item>
</template>
<script>
import {channelList} from "@/utils/app-channel";
export default {
  name: "Index",
  data() {
    return {
      //渠道列表 全部渠道
      channelList: channelList,
      //  checkbox 的不确定状态，一般用于实现全选的效果
      isIndeterminateBool: true,
      //全选默认不勾选
      checkAll: false,
      data: this.checkList,
    }
  },
  computed: {
    checkList: {
      get: function () {
        return (this.item[this.formDBName] || '').split("|").filter(str => (!!str));
      },
      set: function (newValue) {
        this.item[this.formDBName] = newValue.join("|");
      }
  props: {
    //表单名称
    label: {
      type: String,
      required: true
    },
    //当前选中项
    item: {
      type: Object,
    formDBName: {
  methods: {
    getArrayCheckList() {
      return (this.item[this.formDBName] || '').split("|").filter(str => (!!str));
    //将数据返回给父组件
    setChooseData(data) {
      this.$emit("choose-data", this.formDBName, data)
    //value 代表选中还是未选中 ture false两个取值
    handleCheckAllChange(value) {
      const chooseChannel = Object.keys(this.channelList)
      this.checkList = value ? chooseChannel : [];
      this.isIndeterminateBool = false;
      this.checkAll = value;
      const formData = this.checkList.join("|");
      this.setChooseData(formData)
    //选中后计算全选
    handleCheckedCitiesChange(value) {
      const chooseChannel = Object.keys(this.channelList);
      let checkedCount = value.length;
      this.checkAll = checkedCount === chooseChannel.length;
      this.isIndeterminateBool = checkedCount > 0 && checkedCount < chooseChannel.length;
      const formData = value.join("|");
  mounted() {
    // .split("|").filter(str => (!!str && typeof (str) == 'string'))
  }
}
</script>
<style scoped>
</style>

渠道列表

//

export const channelList = {
    "anguo": "安果",
    "baidu": "百度",
    "huawei": "华为",
    "samsung": "三星",
    "oppo": "OPPO",
    "sanliuling": "360",
    "meizu": "魅族",
    "vivo": "VIVO",
    "wandoujia": "豌豆荚",
    "xiaomi": "小米",
    "yyb": "应用宝",
    "yyh": "应用汇",
};

父组件使用

 <el-card shadow="hover">

            <multiple-choice :item="item" label="渠道/广告开关"
                             form-d-b-name="channel" @choose-data="onCheckResult"></multiple-choice>
          </el-card>

item[channle] 是存入字符串的以|分割的数据

比如

baidu|anguo|yyb

这样

onCheckResult

onCheckResult(dbName, res) {
      this.item[dbName] = res;
    }
