微信小程序消息推送，前端操做

<form bindsubmit="getFormId" report-submit="true">
    <button form-type="submit">
      当即预定
    </button>
  </form>

form_submit: function (e) {
    console.log(e)
    if (e.detail.formId === 'the formId is a mock one') {
      return
    } else {
      let data = { formId: e.detail.formId }
      调用后台接口
    }
  }
