select验证

select 下拉框
注：　直接使用this.$refs.orderForm.clearValidate()对select不生效

 gender: [
          { required: true, message: '请选择性别', trigger: ['blur', 'change'] }
        ],

// 清除表单验证
this.$refs.orderForm.clearValidate()
// 清除自动触发的表单验证
this.$nextTick(() => {
      this.$refs['orderForm'].clearValidate()
})
