localStorage cleared on app restart with Cordova 1.7 and iOS 5.1.1

问题

From my extensive reading, the iOS 5.1 localStorage/WebSQL behavior change that Apple instituted has been fully rolled into Cordova 1.6.0. However, while running on my (new) application on Cordova 1.7.0 and iOS 5.1.1, I am still seeing ugly, incorrect behavior.

I use window.localStorage to store and retrieve data. E.g. window.localStorage.getItem("activeFormId") window.localStorage.setItem("activeFormId", formId); These work flawlessly during the same session of the Cordova-based app. If I background the app with the main iOS button then resume, that usually works as well.

However, the moment I kill the application (double-tap, long-press, tap the red circle) and relaunch, all localStorage data is lost. I have verified this with jsconsole.com as well.

Are there additional steps I need to take to ensure the persistence bug fixes are working? Any help is greatly appreciated.

回答1:

Try using 1.7 - I had a similar issue and once I upgraded to 1.7 everything worked like it used to.

Try using localStorage vs window.localStorage syntax.

Also set what ever you're trying to call as a global variable...

var globalVar;

function onDeviceReady(){
  globalVar = localStorage.getItem('something');
}
