app.js
// app.js
App({
onLaunch(e) {
// 判断屏幕大小
var judgeBigScreen = () => {
let result = false;
const res = wx.getSystemInfoSync();
const rate = res.windowHeight / res.windowWidth;
let limit = res.windowHeight == res.screenHeight ? 1.8 : 1.65; // 临界判断值
if (rate > limit) result = true;
return result;
}
this.globalData.judgeBigScreen = judgeBigScreen();
},
globalData: {
judgeBigScreen:false,
}
})定义好之后在需要判断的页面使用即可
var app = getApp()
Page({
data: {
},
onLoad(options) {
console.log('是否为长屏', app.globalData.judgeBigScreen);
},
})
