<!--index.wxml-->
<view class="container">

 <navigator url="../demo/demo?title=參數(shù)傳遞">title=參數(shù)傳遞</navigator>
</view>

// pages/demo/demo.js
Page({

 data: {
 title:''
 },

 onLoad: function (options) {
 console.log(options) //打印options,可以看到title的值可以獲取到
 this.setData({
 title:options.title //為頁(yè)面中title賦值
 })
 },
})

<!--pages/demo/demo.wxml-->
<view class='container'>
 {{title}}
</view>

//app.js
App({
 globalData: {}

<view class="container" bindtap='goto_demo'>
