element-ui表單校驗

必須注意巨坑：el-form-item上的prop要和 v-model的值名字相同，否則會無效 

一、文本框、多選校驗

 

 

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
  <el-form-item label="活動名稱" prop="name">
    <el-input v-model="ruleForm.name"></el-input>
  </el-form-item>
  <el-form-item label="活動區域" prop="region">
    <el-select v-model="ruleForm.region" placeholder="請選擇活動區域">
      <el-option label="區域一" value="shanghai"></el-option>
      <el-option label="區域二" value="beijing"></el-option>
    </el-select>
  </el-form-item>
  <el-form-item label="活動時間" required>
    <el-col :span="11">
      <el-form-item prop="date1">
        <el-date-picker type="date" placeholder="選擇日期" v-model="ruleForm.date1" style="width: 100%;"></el-date-picker>
      </el-form-item>
    </el-col>
    <el-col class="line" :span="2">-</el-col>
    <el-col :span="11">
      <el-form-item prop="date2">
        <el-time-picker placeholder="選擇時間" v-model="ruleForm.date2" style="width: 100%;"></el-time-picker>
      </el-form-item>
    </el-col>
  </el-form-item>
  <el-form-item label="即時配送" prop="delivery">
    <el-switch v-model="ruleForm.delivery"></el-switch>
  </el-form-item>
  <el-form-item label="活動性質" prop="type">
    <el-checkbox-group v-model="ruleForm.type">
      <el-checkbox label="美食/餐廳線上活動" name="type"></el-checkbox>
      <el-checkbox label="地推活動" name="type"></el-checkbox>
      <el-checkbox label="線下主題活動" name="type"></el-checkbox>
      <el-checkbox label="單純品牌曝光" name="type"></el-checkbox>
    </el-checkbox-group>
  </el-form-item>
  <el-form-item label="特殊資源" prop="resource">
    <el-radio-group v-model="ruleForm.resource">
      <el-radio label="線上品牌商贊助"></el-radio>
      <el-radio label="線下場地免費"></el-radio>
    </el-radio-group>
  </el-form-item>
  <el-form-item label="活動形式" prop="desc">
    <el-input type="textarea" v-model="ruleForm.desc"></el-input>
  </el-form-item>
  <el-form-item>
    <el-button type="primary" @click="submitForm('ruleForm')">立即創建</el-button>
    <el-button @click="resetForm('ruleForm')">重置</el-button>
  </el-form-item>
</el-form>
<script>
  export default {
    data() {
      return {
        ruleForm: {
          name: '',
          region: '',
          date1: '',
          date2: '',
          delivery: false,
          type: [],
          resource: '',
          desc: ''
        },
        rules: {
          name: [
            { required: true, message: '請輸入活動名稱', trigger: 'blur' },
            { min: 3, max: 5, message: '長度在 3 到 5 個字符', trigger: 'blur' }
          ],
          region: [
            { required: true, message: '請選擇活動區域', trigger: 'change' }
          ],
          date1: [
            { type: 'date', required: true, message: '請選擇日期', trigger: 'change' }
          ],
          date2: [
            { type: 'date', required: true, message: '請選擇時間', trigger: 'change' }
          ],
          type: [
            { type: 'array', required: true, message: '請至少選擇一個活動性質', trigger: 'change' }
          ],
          resource: [
            { required: true, message: '請選擇活動資源', trigger: 'change' }
          ],
          desc: [
            { required: true, message: '請填寫活動形式', trigger: 'blur' }
          ]
        }
      };
    },
    methods: {
      submitForm(formName) {
        this.$refs[formName].validate((valid) => {
          if (valid) {
            alert('submit!');
          } else {
            console.log('error submit!!');
            return false;
          }
        });
      },
      resetForm(formName) {
        this.$refs[formName].resetFields();
      }
    }
  }
</script>

　　

二、圖片上傳校驗

　　

 

 

<el-form-item ref="images" label="圖片" prop="image">
<el-upload class="uploader" action="placeholder" accept="image/jpeg,image/png,image/jpg" :show-file-list="false" :http-request="upload_image">
<img v-if="image" :src="image" class="avatar">
<i v-else class="el-icon-plus avatar-uploader-icon" />
<div slot="tip" class="el-upload__tip">支持的圖片格式：jpg png，大小2M以內。</div>
</el-upload>
</el-form-item>
<script>

　　

 export default {
    data() {
      return {
　　　　　image:'',
        rules: {
          imgae: [{required:true,message:'請上傳圖片'}]
        }

      };
    },
    methods: {
      upload_image() {
　　　　　//上傳圖片成功之后，通過ref對錯誤提示進行清除
        this.$refs[images].clearValidate();
      }
    }
  }

</script>
