uniapp APP版本更新

var dtask = plus.downloader.createDownload(userl.value, {}, function(d, status) {

进度
onProgress(task) { //  获取下载进度

p判断版本号是否小于当前线上版本

plus.runtime.getProperty(plus.runtime.appid, function (inf) {
				console.log('当前应用版本号:',  parseInt(inf.versionCode), parseInt(res.data.apkVersion),parseInt(inf.versionCode) < parseInt(res.data.apkVersion))
				if (parseInt(inf.versionCode) < parseInt(res.data.apkVersion)) {
					uModal.value.open()
					console.log(res,"参数--")
					userl.value=res.data.path
				}
