})
const accountCollection = db.collection("data");

//引用集合
Page({
data: {
userdata:[]
},
onLoad: function (options) {
var that = this;
var username = wx.getStorageSync('username');
var userdata = this.data.userdata;
db.collection('data').where({
name:username
}).get({ success: res => {
this.setData({
userdata:res.data,
})
console.log(res.data)
console.log(res.data[0].testscorecloud)
console.log("userdata",userdata)
} });
console.log(userdata)
},
