组件-Element—Transfer（穿梭框）

组件-Element—Transfer（穿梭框）

组件—穿梭框

1. 基础用法
   

   <template>
     <el-transfer v-model="value" :data="data"></el-transfer>
   </template>
   
   <script>
     export default {
       data() {
         const generateData = _ => {
           const data = [];
           for (let i = 1; i <= 15; i++) {
             data.push({
               key: i,
               label: `备选项 ${ i }`,
               disabled: i % 4 === 0
             });
           }
           return data;
         };
         return {
           data: generateData(),
           value: [1, 4]
         };
       }
     };
   </script>
   

2. 可搜索
   

   <template>
     <el-transfer
       filterable
       :filter-method="filterMethod"
       filter-placeholder="请输入城市拼音"
       v-model="value"
       :data="data">
     </el-transfer>
   </template>
   
   <script>
     export default {
       data() {
         const generateData = _ => {
           const data = [];
           const cities = ['上海', '北京', '广州', '深圳', '南京', '西安', '成都'];
           const pinyin = ['shanghai', 'beijing', 'guangzhou', 'shenzhen', 'nanjing', 'xian', 'chengdu'];
           cities.forEach((city, index) => {
             data.push({
               label: city,
               key: index,
               pinyin: pinyin[index]
             });
           });
           return data;
         };
         return {
           data: generateData(),
           value: [],
           filterMethod(query, item) {
             return item.pinyin.indexOf(query) > -1;
           }
         };
       }
     };
   </script>
   

3. 可自定义
   
   

   <template>
     <p style="text-align: center; margin: 0 0 20px">使用 render-content 自定义数据项</p>
     <div style="text-align: center">
       <el-transfer
         style="text-align: left; display: inline-block"
         v-model="value"
         filterable
         :left-default-checked="[2, 3]"
         :right-default-checked="[1]"
         :render-content="renderFunc"
         :titles="['Source', 'Target']"
         :button-texts="['到左边', '到右边']"
         :format="{
           noChecked: '${total}',
           hasChecked: '${checked}/${total}'
         }"
         @change="handleChange"
         :data="data">
         <el-button class="transfer-footer" slot="left-footer" size="small">操作</el-button>
         <el-button class="transfer-footer" slot="right-footer" size="small">操作</el-button>
       </el-transfer>
     </div>
     <p style="text-align: center; margin: 50px 0 20px">使用 scoped-slot 自定义数据项</p>
     <div style="text-align: center">
       <el-transfer
         style="text-align: left; display: inline-block"
         v-model="value4"
         filterable
         :left-default-checked="[2, 3]"
         :right-default-checked="[1]"
         :titles="['Source', 'Target']"
         :button-texts="['到左边', '到右边']"
         :format="{
           noChecked: '${total}',
           hasChecked: '${checked}/${total}'
         }"
         @change="handleChange"
         :data="data">
         <span slot-scope="{ option }">{{ option.key }} - {{ option.label }}</span>
         <el-button class="transfer-footer" slot="left-footer" size="small">操作</el-button>
         <el-button class="transfer-footer" slot="right-footer" size="small">操作</el-button>
       </el-transfer>
     </div>
   </template>
   
   <style>
     .transfer-footer {
       margin-left: 20px;
       padding: 6px 5px;
     }
   </style>
   
   <script>
     export default {
       data() {
         const generateData = _ => {
           const data = [];
           for (let i = 1; i <= 15; i++) {
             data.push({
               key: i,
               label: `备选项 ${ i }`,
               disabled: i % 4 === 0
             });
           }
           return data;
         };
         return {
           data: generateData(),
           value: [1],
           value4: [1],
           renderFunc(h, option) {
             return <span>{ option.key } - { option.label }</span>;
           }
         };
       },
   
       methods: {
         handleChange(value, direction, movedKeys) {
           console.log(value, direction, movedKeys);
         }
       }
     };
   </script>
   

4. 数据项属性别名
   

   <template>
     <el-transfer
       v-model="value"
       :props="{
         key: 'value',
         label: 'desc'
       }"
       :data="data">
     </el-transfer>
   </template>
   
   <script>
     export default {
       data() {
         const generateData = _ => {
           const data = [];
           for (let i = 1; i <= 15; i++) {
             data.push({
               value: i,
               desc: `备选项 ${ i }`,
               disabled: i % 4 === 0
             });
           }
           return data;
         };
         return {
           data: generateData(),
           value: []
         };
       }
     };
   </script>
