這篇文章主要介紹了vue2.0 element-ui中的el-select選擇器無法顯示選中的內容,在文中小編使用的是element-ui V2.2.3。具體解決方法及示例代碼大家參考下本文

我使用的是element-ui V2.2.3。代碼如下，當我選擇值得時候，el-select選擇器無法顯示選中的內容，但是能觸發(fā)change方法，并且能輸出選擇的值。

select.vue文件

<template>
 <div>
 <div class="row" v-for="RowItem in rows">
  <div class="col" v-for="colItem in RowItem.configVos">
  <el-select v-model="formData[colItem.paramCode]" :class="getModel(colItem.paramCode)" @change="onSelectChange(colItem.paramCode,formData[colItem.paramCode])">
   <el-option v-for="option in colItem.configOptions" :label="option.optionCode" 
   :value="option.optionValue" >
   </el-option>
 </el-select>
  </div> 
 </div> 
 </div> 
</template>
<script>
 import axios from 'axios';
 export default {
 data() {
  return {
  groupItem:{},
  formData:{},
  rows:'',
  cols:''
  }
 },
 watch:{
 },
 methods:{  
  getfordata:function(){
  var _this = this;
  axios.get('../json/selectdata.json')
  .then(function(res){
   _this.groupItem = res.data;
   var row = _this.groupItem[0].rowData;
   _this.rows = row;  
   for(var i=0;i<row.length;i++){
   var col = row[i].configVos;   
   for(var j=0;j<col.length;j++){ 
    var key = col[j];    
    _this.formData[key.paramCode] = '';  
   }
   }   
  })
  },
  onSelectChange:function(key,val){
  console.log(val);
  },
  getModel(model) {
  console.log(model);
  }
 },
 created:function(){
  this.getfordata();
 }
 }
</script>
<style scoped>
 .col{
 float:left;
 }
 .row{
 width:800px;
 height:100px;
 }
</style>
