如何比较result和answer并用scoer算出总分？一直提示Setting data field "score" to undefined is invalid.并且结果页面的scoer显示为零。
// pages/result/result.js
Page({
/**
* 页面的初始数据
*/
data: {
score:0,
},
anew:function(e){
wx.reLaunch({
url: '/pages/test/test',
})
},
/**
* 生命周期函数--监听页面加载
*/
onLoad(options) {
var uname = wx.getStorageSync('uname')
this.setData({
uname:uname,
score:options.score,
})
},
})
<view class="page_result">
<button class="new" bindtap="anew">重新测试button>
<view class="score">{{uname}}你的总分为：{{score}}view>
