getApp()The globalData () function is used to get the current application instance, typically globalData.

1. Uni-app defines globalData in app.vue file

export default {
		globalData: {lists: [].datainfo: {}}},Copy the code

2. Other page references can be directly assigned

In other files it is called with getApp().globalData


getlevel4() {
	this.$http({
	url: ' '
	}).then(res= > {
	getApp().globalData.lists = res.data;
	}).catch(err= >{})},Copy the code

3. Then you can also upload to other pages to directly call the assignment

onLoad(){
		this.headerlist = getApp().globalData.lists; },Copy the code

$scope. GlobalData = this.$scope. GlobalData = this.$scope

To get it in another child page, use getApp().globalData
