vue.javascript如何实现的全选与全不选功能示例【基于elementui】

本文实例讲述了vue.js实现的全选与全不选功能。分享给大家供大家参考，具体如下：

elementui是有checkbox组件，不过问题在于checkbox组件内只能嵌套简单的字符串，如果要嵌入标签怎么办?

首先渲染页面：

<el-checkbox v-model="checkAll" @change="handleCheckAllChange">全选</el-checkbox>
<tbody v-for="item in orderData">
 <tr>
  <td class="order-num" colspan="7">
   <el-checkbox v-model="item.checkModel" @change="handleCheckItemChange" style="vertical-align:top;margin-top:20px;"></el-checkbox>
   <div class="num">
    <a rel="nofollow noopener noreferrer" href="javascript：;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >订单号：{{item.orderNumber}}</a>
    <p>商户单号：{{item.shopNumber}}</p>
   </div>
  </td>
  <td class="order-action" colspan="2">
   <a rel="nofollow noopener noreferrer" href="javascript：;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >查看详情</a>-<a rel="nofollow noopener noreferrer" href="javascript：;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >备注</a>-<a rel="nofollow noopener noreferrer" href="javascript：;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >加星</a>
  </td>
 </tr>
 <tr>
  <td>
   <div class="pic">
    <img :src=item.orderPic alt="">
   </div>
   <div class="info">
    <a rel="nofollow noopener noreferrer" href="javascript：;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{{item.name}}</a>
    <p>{{item.size}}</p>
    <p>商品来源：{{item.from}}</p>
   </div>
  </td>
  <td>{{item.number}}</td>
  <td>{{item.price}}</td>
  <td>-</td>
  <td>{{item.company}}</td>
  <td>
   <p>{{item.address}}</p>
   <p>({{item.phone}})</p>
  </td>
  <td>{{item.date}}<br />{{item.time}}</td>
  <td>{{item.state}}</td>
  <td>{{item.pay}}<br /><span v-if="item.postCost">(运费：{{item.postCost}})</span></td>
 </tr>
</tbody>

初始化data数据：

checkAll:false,
checkedAllShops:[],
checkItemData:[],
orderData:[
 {
  checkModel:false,
  orderNumber:'2017081618322542542',
  shopNumber:'2017081618322542542',
  orderPic:'../../../../static/images/realtimeprofile01.png',
  name:'【商城】贴轻松穴位艾灸贴',
  size:'5贴*盒',
  from:'本店商品',
  number:'10',
  price:'200.00',
  company:'蒂花之秀',
  address:'童话镇',
  phone:'12345678910',
  date:'2018-1-12',
  time:'09:30:00',
  state:'订单关闭',
  pay:'400.00',
  postCost:'10'
 },{
  checkModel:false,
  orderNumber:'2017081618322542542',
  shopNumber:'2017081618322542542',
  orderPic:'../../../../static/images/realtimeprofile01.png',
  name:'【商城】贴轻松穴位艾灸贴',
  size:'5贴*盒',
  from:'本店商品',
  number:'10',
  price:'200.00',
  company:'蒂花之秀',
  address:'童话镇',
  phone:'12345678910',
  date:'2018-1-12',
  time:'09:30:00',
  state:'订单关闭',
  pay:'400.00',
  postCost:'10.00'
 }
]

相关方法：

handleCheckAllChange(val){
 this.orderData.map((item,i)=>{
  item.checkModel = val;
 })
},
handleCheckItemChange(val){
 for(let i = 0,l = this.orderData.length;i < l;i ++){
  if(this.orderData[i].checkModel !== val){
   this.checkAll = false;
   return;
  }
 }
 this.checkAll = val;
}

css代码就不贴出来了，不好看，哈哈
