localStorage在使用Cordova 1.7和iOS 5.1.1重新启动应用程序时清除

问题描述

从我广泛的阅读，iOS 5.1 localStorage / WebSQL行为更改，苹果已经完全推广到Cordova 1.6.0。
然而，当我在Cordova 1.7.0和iOS 5.1.1的我的（新）应用程序上运行时，我仍然看到丑陋，不正确的行为。

使用window.localStorage存储和检索数据。例如。
window.localStorage.getItem（activeFormId）
window.localStorage.setItem（activeFormId，formId）;
这些工作在基于Cordova的应用程序的同一会话期间完美无缺。如果我使用主要的iOS按钮背景的应用程序，然后恢复，这通常也很好。

然而，一旦我杀了应用程序（双击，长按，点击红色圆圈）并重新启动，所有localStorage数据都丢失。我已经验证了这个与jsconsole.com以及。

我需要采取额外的步骤，以确保持久性错误修复工作？非常感谢任何帮助。

解决方案

尝试使用1.7 - 我有一个类似的问题，一旦我升级到1.7一切都像

尝试使用localStorage与window.localStorage语法。

还要设置您尝试的内容作为全局变量调用...

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

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.

解决方案

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');
}
