[图片][图片] 想要实现的效果是在recharge下第一行数据0：中的"type" 设置为null， 而不是新增一行新的数据。应该怎么操作呢？

[图片][图片] 上图分别为在云函数中 定义的函数 以及 调用该函数生成的参数。请问怎么把这个参数传到普通页面中去呢？

const _ = db.command   // 2 查询当前openid是否 不在数据库中         db.collection('todos').where({           _openid: _.neq(res.result.openid) // 不等于打印出来的当前用户openid         }) .add({  // 3.1  不在：添加数据(点数)               data: {                 point: point                }             }) 报错db.collection('todos').where.add不是函数，求解决方法！ 已解决：  const _ = DB.command   // 2 查询当前openid是否在数据库中         DB.collection('todos').where({           _openid: res.result.openid //数据库中_openid等于当前用户openid的数据         })         .get({           success: function(res) {             console.log(res.data)             if(res.data.length === 0){ // 为空 即 数据库中没有该用户 _openid               DB.collection('todos').add({  // 增加数据(点数)                 data: {                   point: point                  }               })               }                        }         })
