This article mainly introduces "how WeChat Mini Programs realizes sharing data between pictures". In daily operation, I believe that many people have doubts about how WeChat Mini Programs can share data between screens. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how WeChat Mini Programs can achieve data sharing between pictures". Next, please follow the editor to study!

Sequence diagram

In order to straighten out the user's operation logic, we divide the setting of the monitoring point into two screens: selecting the monitoring point and editing the monitoring condition.

In order to generalize the process of creating a new monitoring point and editing a monitoring point, the task of creating a monitoring point object is assigned to the main screen.

The sequence diagram is as follows:

Index.js

NewButtonTaped: function () {

Console.log ("index.js::newButtonTaped")

This.mapCtx.getCenterLocation ({

Success: function (res) {

App.globalData.currentAlarm = {

Longitude: res.longitude

Latitude: res.latitude

}

Wx.navigateTo ({

Url:'.. / setpoint/setpoint'

})

}

})

}

While creating the monitoring point screen, set the initial value of the coordinates.

Setpoint.js

GetPoisInformation:function () {

Var that = this

Var mapCtx = wx.createMapContext ('alarmMap')

MapCtx.getCenterLocation ({

Success: function (res) {

Util.getPoisByLocation (res.longitude, res.latitude, function (data) {

Console.log (data)

That.setData ({

Pois: data.pois

Location: res.latitude.toFixed (4) +','+ res.longitude.toFixed (4)

});

App.globalData.currentAlarm = {

Longitude: res.longitude

Latitude: res.latitude

Title: data.pois [0] .title

}

})

}

})

}

Set the coordinates and the monitoring point title. The picture is as follows:

Dalian Convention Center is selected on the screen. Above is the famous Music Fountain Square.

Editaction.js

The function of editing the monitoring condition screen is under preparation. Let's show you the picture first.

The screen is only a prototype, and the location and ringtone specified by the selected monitoring point can be displayed at present. After you select a different ringtone, you can play it.

At this point, the study on "how WeChat Mini Programs can share data between pictures" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
