This article will introduce to you two methods of value transfer between pages in WeChat mini programs. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
1: url transfer with parameters
Like front-end languages, transfer between mini program pages You can add parameters after the routing url, and the parameters will be passed to the new page during routing.
index.wxml:
<!--index.wxml--> <view class="container"> <!-- 使用navigator组件 --> <navigator url="../demo/demo?title=参数传递">title=参数传递</navigator> </view>
demo.js
// pages/demo/demo.js Page({ data: { title:'' }, onLoad: function (options) { console.log(options) //打印options,可以看到title的值可以获取到 this.setData({ title:options.title //为页面中title赋值 }) }, })
demo.wxml
<!--pages/demo/demo.wxml--> <view class='container'> {{title}} </view>
Rendering:
Two: Will Values are stored in global variables
We can also store the required values in global variables and directly reference them where needed.
app.js
//app.js App({ globalData: {} })
index.wxml
<!--index.wxml--> <!-- 点击触发goto_demo函数 --> <view class="container" bindtap='goto_demo'> title=参数传递 </view>
index.js
//index.js //获取应用实例 const app = getApp() Page({ data: { title:'参数传递' }, goto_demo: function() { app.globalData.title = this.data.title wx.navigateTo({ url: '../demo/demo', }) } })
demo.js
// pages/demo/demo.js //获取应用实例 const app = getApp() Page({ data: { title:'' }, onLoad: function (options) { console.log(app.globalData.title) //打印options,可以看到title的值可以获取到 this.setData({ title: app.globalData.title //为页面中title赋值 }) }, })
Required When using global variables, remember to get the application instance first: const app = getApp()
The rendering is the same as above.
