一、ElementUI 自定义表单验证

  1. 自定义表单验证
    页面表单 
<tempalte>
  <div>
    <el-form :model="ruleForm" status-icon :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
      <el-form-item label="银行卡密码" prop="password">
        <el-input v-model="ruleForm.password" autocomplete="off"></el-input>
      </el-form-item>
      <el-form-item>
	    <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>
	    <el-button @click="resetForm('ruleForm')">重置</el-button>
	  </el-form-item>
    </el-form>
  </div>
</tempalte>
<script>
  export default {
   
    data() {
   
      //自定义密码表单验证规则
      const checkPass = (rule, value, callback) => {
   
        // 正则表达式验证
        const regPass = /^[0-9]{
   6}$/
        if(vlaue === "") {
   
          callback(new Error('密码不能为空!'))
        }else if(!(regPass.test(value))) {
   
          callback(new Error('密码只能为6位数字组成!'))
        }
        
        return callback()
      };
      return {
   
        ruleForm: {
   
          password: '',
        },
        rules: {
   
          password: [
            {
    validator: checkPass, 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>
