[JavaScript知识库]uniapp 全局变量

1.在APP.vue中设置globalData

<script>
	export default {
		onLaunch: function() {
			console.log('App Launch')
		},
		onShow: function() {
			console.log('App Show')
		},
		onHide: function() {
			console.log('App Hide')
		},
		globalData:{
			id:"666666666666666666"
		}
	}
</script>

<style>
	/*每个页面公共css */
	@import 'graceUI/graceUI.css';
</style>

使用与赋值

console.log(getApp().globalData.id)
getApp().globalData.id = "88888888888888888888888"
console.log(getApp().globalData.id)

2.在main.js中将变量挂载到vue原型上

Vue.prototype.apiServer = 'http://192.168.0.108/index.php?token='+APITOKEN+'&c=';
Vue.prototype.hhh = 'hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh';

使用与赋值

uni.request({
			url: _this.apiServer + 'member&m = login',
			method: 'POST',
			header: {
				'content-type': "application/x-www-form-urlencoded"
			},
			data: {
			openid: openid,
			name: nickName,
			face: avatarUrl
			},
			success: res => {
				
								
			},
			fail: () => {
					console.log("请求失败")
			}
			})

 
              console.log(this.hhh)
  			  this.hhh = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
		      console.log(this.hhh)
