基于vue实现的多条件联动筛选功能（类似中国移动商城），选中，反选，删除功能。
UI库用的ivew

先来张实现的效果图

展开时候的效果

收起时候的效果

代码如下：

1. html（用了iview的UI库）

 <div class="filter-more">
      <transition name="selectbox">
        <div class="box" v-show="boxshow">
          <Row v-for="(item,index) in filterBox" :key="index">
            <i-col span="2">{{item.name}}</i-col>
            <i-col span="22">
              <a href="#"
                v-for="(v,i) in item.items"
                :key="i"
                @click="clickrange(index,v,i)"
                class="text-filter"  >
                <span :class="{ isActive:v.active}">{{v.text}}</span>
              </a>
            </i-col>
          </Row>
        </div>
      </transition>
      <div>
        <a href="#" v-for="(item,index) in selectBox" class="text-select" :key="index">
          {{item.text}}
          <i @click="removeCurrentSelect(index)">&times;</i>
        </a>
      </div>
      <p class="text-toggle" @click="togglebox">{{btnTxt ?'收起选项':'更多选项'}}</p>
    </div>

2.初始化数据

data() {
    return {
      boxshow: false,
      btnTxt: false,
      selectBox: [],
      filterBox: [
        {
          name: '搜索范围:',
          items: [
            { value: '1', text: '全部', active: false },
            { value: '2', text: '诊断信息', active: false },
            { value: '3', text: '手术信息', active: false },
            { value: '4', text: '医嘱处方', active: false },
            { value: '5', text: '检验报告', active: false },
            { value: '6', text: '检查报告', active: false },
            { value: '7', text: '病历文书', active: false }
          ]
        },
        {
          name: '患者年龄:',
          items: [
            { value: 'allAge', text: '全部', active: false },
            { value: 'treeY', text: '0~3岁', active: false },
            { value: 'fourteenY', text: '4~14岁', active: false },
            { value: 'fortyY', text: '15~40岁', active: false },
            { value: 'sixtyY', text: '41~65岁', active: false },
            { value: 'enghtyY', text: '65~85岁', active: false },
            { value: 'ninetyY', text: '85岁以上', active: false }
          ]
        },
        {
          name: '患者性别:',
          items: [
            { value: 'allSex', text: '全部', active: false },
            { value: 'man', text: '男', active: false },
            { value: 'women', text: '女', active: false },
            { value: 'unknow', text: '未知', active: false }
          ]
        },
        {
          name: '就诊类别:',
          items: [
            { value: '1', text: '全部', active: false },
            { value: '2', text: '门诊', active: false },
            { value: '3', text: '急诊', active: false },
            { value: '4', text: '住院', active: false }
          ]
        },
        {
          name: '就诊时间:',
          items: [
            { value: '1', text: '全部', active: false },
            { value: '2', text: '2009年', active: false },
            { value: '3', text: '2018年', active: false },
            { value: '4', text: '2017年', active: false },
            { value: '5', text: '2016年', active: false },
            { value: '6', text: '2015年', active: false },
            { value: '7', text: '2014年', active: false },
            { value: '8', text: '更多', active: false }
          ]
        },
        {
          name: '手术病人:',
          items: [
            { value: '1', text: '全部', active: false },
            { value: '2', text: '手术病人', active: false },
            { value: '3', text: '非手术病人', active: false }
          ]
        }
      ]
    };
  },

JS逻辑代码

methods: {
    togglebox: function() {
      this.boxshow = !this.boxshow;
      this.btnTxt = !this.btnTxt;
    },
    clickrange(parentIndex, el, childIndex) {
      var item = this.filterBox[parentIndex].items;
      item.filter((v, i) => {
        if (i === childIndex) {
          v.active = !v.active; // 选中和反选
          this.selectBox.unshift(v); // 选中的数组
        } else {
          v.active = false; // 取消选中
          this.selectBox.filter((childEl, childI) => {
            if (childEl.active === false) {
              this.selectBox.splice(childI, 1); // 反选删除数组中的当前个
            }
          });
        }
      });
    },
    removeCurrentSelect(index) {
      this.filterBox.filter((el, i) => {
        el.items.filter((data, childIndex) => {
          if (data.text == this.selectBox[index].text) {
            data.active = false;
          }
        });
      });
      this.selectBox.splice(index, 1);
    }，
  },
