做网站和做软件哪个难阿里指数查询

参考文档：HTML5+ API Reference

项目中需要判断是否安装了uber，这里拿uber举例 ，判断是否安装uber

if (plus.runtime.isApplicationExist({pname: 'com.ubercab.eats', //Android平台通过pname属性（包名）查询action: 'ubereats://store/browse' //  iOS平台通过action属性（Scheme）进行查询})) {plus.runtime.launchApplication({pname: "com.ubercab.eats",extra: {test: "ceshi"}}, function(e) {console.log("Open system default browser failed: " + e.message);});
} else {uni.showModal({title: 'Tip',content: 'Application not installed',cancelText: 'Cancel',confirmText: "Install",success: (res) => {if (res.confirm) {if(plus.os.name == "Android"){//谷歌商店的uber下载地址plus.runtime.openURL('https://play.google.com/store/apps/details?id=com.ubercab.eats',(err) => {console.log('err', err)}, '');}else if(plus.os.name == "iOS"){//App Store下载地址plus.runtime.openURL('https://apps.apple.com/us/app/uber-eats-food-delivery/id1058959277', (err) => {console.log('err', err)}, '');}}})
}
