JS interaction logic

It is not enough for a service to just show the interface, it also needs to interact with the user: responding to the user's click, getting the user's location, and so on. In Mini Program, we deal with users' operations by writing JS script files.

Page ({

ClickMe: function () {this.setData ({msg: "Hello World"})}})

When we click the button button, we want to display the msg on the interface as "Hello World", so we declare a property on button: bindtap, and declare the clickMe method in the JS file in response to this click:

Page ({

ClickMe: function () {

This.setData ({msg: "Hello World"})

}

})

Responding to a user's action is as simple as that. For more detailed events, please refer to the documentation WXML-event.
