使用elementUI-【表单验证】的表单，在此基础上进行修改，达到自己需要的样式

eleUI原版代码如下 自行修改需要的样式

    },
    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>
