Cordova Cross-platform app version upgrade

Use Cordova+ionic to develop a good project, followed by a package release, before that, you have to do a version of the upgrade of the small features.

。 Version, we will read the version field from this wiget tag every time we upgrade the app.

Cordova has provided the app version get plugin tool, cordova-plugin-appversion

Gets the version number of the local app via the plugin and gets the version number of the background by request. and then compare.

function Onready () {        cordova.getAppVersion.getVersionNumber (). Then (function (version) {        });        Popup.waitload (' Checking for updatable versions ');        Commonapi.getupgradeversioninfo (function (res) {          if (!res.success) {            throw new Error ("Get App version number information failed" + ( Res.retinfo? Res.retinfo: ""));          }          Popup.hideloading ();          var appversion = res.data.dataObject.serverVersion;          var upgradeinfo = Res.data.dataObject.upgradeInfo;          var url = res.data.dataObject.updateUrl;          Console.log ("Platform is iOS:" + ionic. Platform.isios ());          Gets the current app version information          if (compareversion (version,appversion)) {            showupdateconfirm (upgradeinfo, URL, appversion);          } else {            popup.promptmsg (' No new version available ', ' Update Hint ')}        }, {versionflag:versionflag});      }}    ;

comparison function

Compareversion (version,appversion), front and back conventions, version numbers use the "semantic version". such as x.y.z. The front and rear tables are separated by two points using three numbers.

/** Compare version number * @param localversion local app version number * @param newversion Server return version number * @returns {Boolean}*/    functioncompareversion (localversion, newversion) {Console.log ("New version%s-old version%s", NewVersion, localversion); if(typeofLocalversion = = = ' String ' &&typeofNewVersion = = = ' String '){          varLocalversionarray = Localversion.split ('. ')); varNewversionarray = Newversion.split ('. ')); if(Localversionarray.length = = =newversionarray.length) {               for(vari = 0; i < localversionarray.length; i++){                if(parseint (Newversionarray[i]) >parseint (Localversionarray[i])) {                  return true; }Else if(parseint (Newversionarray[i]) >parseint (Localversionarray[i])) {                  return false; }Else {                  Continue; }              }              return false; }Else{popup.loadmsg (' Version number record error ', 500,function () {                  return;          }); }      }Else{popup.loadmsg (' Version number record error ', 500,function () {            return;      }); }    }
