vue循環綁定v-model

直接上代碼

結構：

<repayInput v-if="formData" v-for="(item, index) in formData"
          :isPwd="item.parameter_code==='password'"
          :text="item.parameter_name.replace('社保網站','')"
          :textAlign="'right'"
          :errText="arrForm[index][`arr${item.parameter_code}`]"
          @changeErrText="_changeErrText2($event,index,'arr'+item.parameter_code)"
          :type="item.parameter_code"
          :maxlength="item.parameter_code==='name'?'15':'50'"
          :placeholder="item.parameter_message"
          v-model="arrForm[index][item.parameter_code]" :key="index">
        </repayInput>

組織arrForm數據

_this.arrForm.length = 0;
          // debugger
          let obj = _this.formInfo[_this.socialType.value].tabs[selectedVal[selectedVal.length-1]].field;
          for(var j=0; j<obj.length; j++) {
            var strObj = `{"${obj[j].parameter_code}":"","arr${obj[j].parameter_code}":"","type":"${obj[j].parameter_code}","name${obj[j].parameter_code}":"${obj[j].parameter_name}"}`;
            // Vue.set(_this.arrForm, obj[j].parameter_code, '');
            // Vue.set(_this.arrForm, `arr${obj[j].parameter_code}`,'');
            _this.arrForm.push(JSON.parse(strObj))
          }

表單驗證：

//驗證動態表單 this.arrForm
      let _this = this;
      for(var i=0; i< _this.arrForm.length; i++) {
        var cur = _this.arrForm[i];
        if( !rValidate.isEmpty(cur[cur.type],() => {
          cur['arr'+cur.type] = cur['name'+cur.type] + '不能為空';
        }) ){
          dyPro = false;
        }
        if( cur.type === 'id_card_num' ){
          if( cur[cur.type]!==_this.query.cardNo ) {//驗證是否與借款人是同一人
            cur['arr'+cur.type] = '請輸入身份認證時身份證賬號';
            dyPro = false;
          }
        }
        if( cur.type === 'cell_phone_num' ){
          if( !rValidate.mobile(cur[cur.type],() => {
            cur['arr'+cur.type] = '手機號碼格式錯誤';
          }) ) {
            dyPro = false;
          }
        }
      }

組織需要提交的數據：

//組織表單參數  applyInfo  _this.arrForm
        let applyInfo = {};
        for(var i=0; i< _this.arrForm.length; i++) {
          var cur = _this.arrForm[i];
          applyInfo[cur.type] = cur[cur.type];
        }
        query_.applyInfo = applyInfo;
