vue基于element-ui的三级CheckBox复选框功能的实现代码


Posted in Javascript onOctober 15, 2018

最近vue项目需要用到三级CheckBox复选框,需要实现全选反选不确定三种状态。但是element-ui table只支持多选行,并不能支持三级及以上的多选,下面通过本文给大家讲解实现方法。

效果图预览:

vue基于element-ui的三级CheckBox复选框功能的实现代码

首先是页面布局,当然也可已使用table,但是自己用flex布局后面更容易增删改查其他功能

<div class="deliverySetting-table">
      <div class="table-head">
        <div class="selection">
          <el-checkbox :indeterminate="indeterminate" v-model="ischeckAll" @change="handleCheckAllChange"></el-checkbox>
        </div>
        <div class="width185">分区名称</div>
        <div class="width265">国家</div>
        <div>派送商</div>
      </div>
      <div class="table-body" v-for="(partition,partitionIndex) in distributorsInfo" :key="partitionIndex">
        <div class="selection">
          <p><el-checkbox :indeterminate="partition.indeterminate" v-model="partition.selected" @change="handleCheckedCountryAllChange(partitionIndex,partition.partitionId,$event)" :key="partitionIndex"></el-checkbox></p>
        </div>
        <div class="width185"><p>{{ partition.partitionName }}</p></div>
        <div class="width265">
          <el-checkbox v-for="country in partition.country" v-model="country.selected" @change="handleCheckedCountryChange(partitionIndex,country.id,partition.partitionId,$event)" :label="country" :key="country.id">{{country.fieldName}}</el-checkbox>
        </div>
        <div>
          <p v-for="(item,index) in partition.country" :key="index">
            {{ item.distributors }}
          </p>
        </div>
      </div>
    </div>

接下来是数据结构,自定义的,可以更后台商议,但是字段indeterminate(显示不确定状态~符号),selected(CheckBox选中状态)一定要让后台加入到data中,其他可以按照后台数据来。

distributorsInfo:[
          { partitionName:'1区',selected:false,partitionId:1,isIndeterminate:false,
            country:[
            {  id: "1",fieldName: "奥地利",fieldTableName: "奥地利",distributors:'UPS',selected: false},
            {  id: "2",fieldName: "芬兰",fieldTableName: "芬兰",distributors:'UPS',selected: false},
            {  id: "3",fieldName: "意大利",fieldTableName: "意大利",distributors:'UPS',selected: false},
            {  id: "4",fieldName: "葡萄牙",fieldTableName: "葡萄牙",distributors:'UPS',selected: false},
            {  id: "9",fieldName: "西班牙",fieldTableName: "西班牙",distributors:'UPS',selected: false},
            {  id: "10",fieldName: "瑞典",fieldTableName: "瑞典",distributors:'UPS',selected: false},]
          },
          { partitionName:'2区',selected:false,partitionId:2,isIndeterminate:false,
            country:[
            {  id: "5",fieldName: "丹麦",fieldTableName: "单买",distributors:'',selected: false},
            {  id: "6",fieldName: "法国",fieldTableName: "法国",distributors:'',selected: false},]
          },
          { partitionName:'3区',selected:false,partitionId:3,isIndeterminate:false,
            country:[
            {  id: "7",fieldName: "德国",fieldTableName: "德国",distributors:'YODEL',selected: false},
            {  id: "8",fieldName: "瑞士",fieldTableName: "瑞士",distributors:'DPD',selected: false}]
          }
        ],
        ischeckAll:false,//一级全选状态

因为此处是三级复选,所以函数为三个change,具体有详细注释可以查看

handleCheckAllChange(e){//一级change事件
        this.ischeckAll = e
        if(e == true){
          this.indeterminate = false
          for(var i=0,len=this.distributorsInfo.length; i<len; i++){ //二级全选反选不确定
            this.distributorsInfo[i].selected = e
            for(var j=0,len1=this.distributorsInfo[i].country.length; j<len1; j++){
              this.distributorsInfo[i].country[j].selected = e
            }
          }
        }else{
          this.indeterminate = false
          for(var i=0,len=this.distributorsInfo.length; i<len; i++){ //三级全选反选不确定
            this.distributorsInfo[i].selected = e
            for(var j=0,len1=this.distributorsInfo[i].country.length; j<len1; j++){
              this.distributorsInfo[i].country[j].selected = e
            }
          }
        }
      },
      handleCheckedCountryAllChange(index, topId, e){//二级change事件
        this.distributorsInfo[index].selected = e//二级勾选后,子级全部勾选或者取消
        if(e == false) this.distributorsInfo[index].indeterminate = false //去掉二级不确定状态
        var childrenArray = this.distributorsInfo[index].country
        if(childrenArray)
          for(var i=0,len=childrenArray.length; i<len; i++)
            childrenArray[i].selected = e

        this.getIsCheckAll()
      },
      handleCheckedCountryChange(topIndex, sonId, topId, e){//三级change事件
        var childrenArray = this.distributorsInfo[topIndex].country
        var tickCount = 0, unTickCount = 0, len = childrenArray.length
        for(var i = 0; i < len; i++){
          if(sonId == childrenArray[i].id) childrenArray[i].selected = e
          if(childrenArray[i].selected == true) tickCount++
          if(childrenArray[i].selected == false) unTickCount++
        }
        if(tickCount == len) {//三级级全勾选
          this.distributorsInfo[topIndex].selected = true 
          this.distributorsInfo[topIndex].indeterminate = false
        } else if(unTickCount == len) {//三级级全不勾选
          this.distributorsInfo[topIndex].selected = false 
          this.distributorsInfo[topIndex].indeterminate = false
        } else {
          this.distributorsInfo[topIndex].selected = false
          this.distributorsInfo[topIndex].indeterminate = true //添加二级不确定状态
        }

        this.getIsCheckAll()
      },
      getIsCheckAll(){
        var tickCount = 0, unTickCount = 0, ArrLength = this.distributorsInfo.length
        for(var j=0; j<ArrLength; j++){//全选checkbox状态
          if(this.distributorsInfo[j].selected == true) tickCount++
          if(this.distributorsInfo[j].selected == false) unTickCount++
        }
        if(tickCount == ArrLength) {//二级全勾选
          this.ischeckAll = true
          this.indeterminate = false
        } else if(unTickCount == ArrLength) {//二级全不勾选
          this.ischeckAll = false
          this.indeterminate = false
        } else {
          this.ischeckAll = false
          this.indeterminate = true //添加一级不确定状态
        }
      },

  .setDistributorDailog{
    .el-input{
      width: 270px;
    }
  }
}
</style>

好了,以后使用三级甚至多级复选都可以使用此方法添加change代码即可。

总结

以上所述是小编给大家介绍的vue基于element-ui的三级CheckBox复选框功能的实现代码,希望对大家有所帮助,如果大家有任何疑问请给我留言,小编会及时回复大家的。在此也非常感谢大家对三水点靠木网站的支持!
