本文實例講述了vue.js實現的全選與全不選功能。分享給大家供大家參考，具體如下：
elementui是有checkbox組件，不過問題在于checkbox組件內只能嵌套簡單的字符串，如果要嵌入標簽怎么辦?
首先渲染頁面：
<el-checkbox v-model="checkAll" @change="handleCheckAllChange">全選</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 href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >訂單號：{{item.orderNumber}}</a> <p>商戶單號：{{item.shopNumber}}</p> </div> </td> <td class="order-action" colspan="2"> <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >查看詳情</a>-<a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >備注</a>-<a 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 </div> <div class="info"> <a 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>商品來源：{{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">(運費：{{item.postCost}})</span></td> </tr></tbody>初始化data數據：
checkAll:false,checkedAllShops:[],checkItemData:[],orderData:[ { checkModel:false, orderNumber:'2017081618322542542', shopNumber:'2017081618322542542', orderPic:'../../../../static/images/realtimeprofile01.png', name:'【商城】貼輕松穴位艾灸貼', size:'5貼*盒', from:'本店商品', number:'10', price:'200.00', company:'蒂花之秀', address:'童話鎮', phone:'12345678910', date:'2018-1-12', time:'09:30:00', state:'訂單關閉', pay:'400.00', postCost:'10' },{ checkModel:false, orderNumber:'2017081618322542542', shopNumber:'2017081618322542542', orderPic:'../../../../static/images/realtimeprofile01.png', name:'【商城】貼輕松穴位艾灸貼', size:'5貼*盒', from:'本店商品', number:'10', price:'200.00', company:'蒂花之秀', address:'童話鎮', phone:'12345678910', date:'2018-1-12', time:'09:30:00', state:'訂單關閉', pay:'400.00', postCost:'10.00' }]相關方法：
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代碼就不貼出來了，不好看，哈哈
希望本文所述對大家vue.js程序設計有所幫助。
