开发项目时自动更新工具。需要获取应用程序的版本。cordova-plugin-app-version可用于获取版本号。可以使用命令行：cordovapluginaddcordova-plugin-app-version，或者在配置文件config.xml和package.json中进行配置。getServerVersion:function(curVersion){vardeferred=$q.defer(),promise;如果(curVersion){promise=$http.get(CONFIG.url.version,{params:{version:curVersion}});}else{promise=$http.get(CONFIG.url.version);}promise.then(function(response){deferred.resolve(response.data.data.versions);}).catch(function(error){deferred.reject(error);});返回deferred.promise；},getLocalVersion:function(){vardeferred=$q.defer();cordova.getAppVersion.getVersionNumber().then(function(localVersion){deferred.resolve(localVersion);}).catch(function(error){deferred.reject(error);});返回deferred.promise；},checkUpdate:function(){varself=this,localVersion;this.getLocalVersion().then(function(response){本地版本n=响应；返回self.getServerVersion（响应）；}).then(function(serverVersions){varlatestVersion=_.isArray(serverVersions)?_.first(serverVersions):serverVersions,laterThanServer=commonService.laterThan(localVersion,latestVersion.number),isForceUpdate=_.some(_.initial(serverVersions),function(item){returnitem.flag===1;});commonService.setItem("latestVersion",latestVersion);returnlaterThanServer&&isForceUpdate;}).then(函数(isForce){isForce&&commonService.confirm(i18n.need_update_label,i18n.force_update_tip).then(function(res){if(res){checkUpdateEnv(isForce);}else{ionic.Platform.exitApp();}});}).catch(function(reason){console.log("versioncomparefiled:"+JSON.stringify(reason));});但是需要注意的一点是，要执行这条语句，必须等待DOM元素加载完成。简单点就是如果在传统的javaScript中使用，需要配合window.onload使用，或者ionic.Platform.ready中的ionic.Platform.ready(function(){if(window.cordova&&window.cordova.plugins&&window.cordova.plugins.Keyboard){window.cordova.plugins.Keyboard.hideKeyboardAccessoryBar(false);window.cordova.plugins.Keyboard.disableScroll(true);apiService.checkUpdate();}try{$cordovaStatusbar.style(0);checkNetworkState();checkSystemVersion();$ionicPlatform.is("Android")&&$ionicPlatform.registerBackButtonAction(registerBackButton,101);}catch(e){console.warn("应用程序出现错误发射：“+e.message);}autoLogin();});相关文章：http://www.ionic.ren/2015/11/...
