el-form 表單檢驗，提交的時候只校驗部分

<template>
  <div>
    <el-form ref="dataFrom" :model="dataFrom" :rules="rules">
      <el-form-item label="用戶名">
        <el-input v-model="dataFrom.userName"></el-input>
      </el-form-item>
    </el-form>
    <el-button @click="submitData()">&nbsp;&nbsp;提交</el-button>
  </div>
</template>

<script>
  export default {
    name: "settlementSignReport",
    data() {
      return {
        dataFrom: {
          userName: ''
        },
        rules: {
          userName: [
            {required: true, message: '請輸入用戶名', trigger: 'blur'},
          ]
        }
      }
    },
    methods: {
      submitData() {
        this.$refs['dataFrom'].validateField('userName', valid => {
          if (!valid) {
            alert(123)
          } else {
            alert(321)
          }
        })
      }
    }
  }
</script>

重點是：用form 表單驗證 validate 的 validateField  去驗證指定的

 

如果要驗證整個表單：

 this.$refs['dataFrom'].validate((valid)=>{
    if(valid){
        //驗證通過
    }
 })
