假条建好,分享id,

Page({
  data: {
    // 假条表单数据
    leaveReason: '',
    leaveTime: '',
    //... 其他假条相关字段
  },
  formSubmit: function (e) {
    const formData = e.detail.value;
    // 向服务器提交假条数据
    wx.request({
      url: 'your_server_api',
      method: 'POST',
      data: formData,
      success: (res) => {
        if (res.statusCode === 200) {
          const leaveId = res.data.leaveId;  // 假设服务器返回假条 ID
          // 进行分享
          this.shareLeave(leaveId);
        }
      }
    });
  },
  shareLeave: function (leaveId) {
    wx.showShareMenu({
      withShareTicket: true
    });
    wx.onShareAppMessage(() => {
      return {
        title: '分享假条',
        path: `/pages/shareLeavePage?leaveId=${leaveId}`
      };
    });
  }
});

分享页接收id查询假条信息显示

Page({
  onLoad: function (options) {
    const leaveId = options.leaveId;
    // 根据假条 ID 从服务器获取假条信息
    wx.request({
      url: `your_server_api/${leaveId}`,
      success: (res) => {
        if (res.statusCode === 200) {
          this.setData({
            leaveInfo: res.data  // 设置假条信息到页面数据
          });
        }
      }
    });
  }
});
