The detailed explanation of the binding click event instance of the WeChat applet

WeChat Mini Program has been out for so long, so I will study it myself while I have time. I looked at it in the previous stage, but individual registration is not allowed. Now it is open to individuals, so enthusiasts can study it on their own.

First, let’s take a look at how to add the bottom tab bar: operate

{ "pages":[ //在这里添加页面的路径 "pages/index/index", "pages/logs/logs", "pages/home/home" ], "window":{ "backgroundTextStyle":"light", "navigationBarBackgroundColor": "#fff", "navigationBarTitleText": "乐动健身馆", "navigationBarTextStyle":"black", "enablePullDownRefresh": true }, //添加标题栏 "tabBar": { "list": [{ "pagePath": "pages/index/index", "text": "首页" }, { "pagePath": "pages/logs/logs", "text": "日志" },{ "pagePath": "pages/home/home", "text": "我的" } ] } }

in app.json and then look at how we modify the data binding through buttons:

Very simple operation, first do the settings in home.wxml:

 //这里{{name}}!来修改所需要绑定的字符串 Hello {{name}}! // bindtap 点击事件 点击我，换名字 

Then do the configuration in home.js:

var helloData ={ name: 'wechat' } Page({ data:helloData, changeName:function(e){ this.setData({ name:'杨磊' }) } })

At this point, we have finished transmitting data to the bound WeChat button
