localStorage在OSX的webview不堅持頁面刷新 - Office365 Addin

Question

我在OSX（埃爾卡皮坦+優勝美地）的webview中localStorage有問題。

我正在製作一個Office365應用程序，它在mac uses a webview上。它在Windows上甚至Safari上都可以正常工作 - 這只是Mac webview的麻煩。它位於託管域中，因此this不是問題所在。

正如您從以下測試代碼中看到的，我將信息保存到localStorage，然後使用該值設置變量。這意味着它在某個時刻必須保存到localStorage，但是如果我刷新頁面，數據將丟失。注意：並非我的應用程序中的所有數據都丟失了，只是一些位。

保存時沒有得到QUOTA_EXCEEDED_ERR。

這是我的測試代碼，刷新失敗。

$scope.initTest = function() { 

    $scope.errorsRecorded += "************** Initialize **************"; 

    var notNested = localStorage.getItem('lclNotNested'); 
    if (!notNested) { 
     $scope.errorsRecorded += "*_*__NOT NESTED NOT SAVED"; 
     $scope.notNested = "NOTSET"; 
    } else { 
     $scope.errorsRecorded += "*_*__NOT NESTED ___ val=" + notNested + ';'; 
     $scope.notNested = JSON.parse(notNested); 
    } 
}; 
$scope.initTest(); 


// Button press event 

$scope.setSingle = function() { 
    // Set the value to localStorage, then get it back for the UI 
    // so we know the value was set. 
    try { 
     localStorage.setItem('lclNotNested', JSON.stringify(Date.now())); 
    } catch (e) { 
     $scope.errorsRecorded = $scope.errorsRecorded + '.....<br/>\r\n ' + e; 
    } 

    $scope.notNested = JSON.parse(localStorage.getItem('lclNotNested')); 
}; 

以下是一些正確設置值的截圖，然後無法加載。

我花了幾個小時試圖弄清楚，不能找到一個方法來調試。我無法訪問底層網頁視圖代碼，它只是微軟提供的一個Web應用程序。

有人知道發生了什麼，或者我可能會如何調試它（例如，查看Mac上webview的localStorage文件）？

Answer 1

辯論刪除的問題，但這樣勢必要抓住別人了...

後頭部的整個負載刮傷和創建此jsfiddle的應用嘗試，似乎Office 365的應用程式不要」目前在OSX上的webview中按照預期堅持localStorage。

我對部分持久性的困惑是有些信息被保存到文檔中。其他（較不重要的）信息僅被保存到localStorage，因此並未持續。

我的例子中的答案是 - 如果您想要在頁面重新加載或爲Office 365應用程序保存並重新打開時保留 - 保存到文檔。不要依賴localStorage做任何事情。

代碼的jsfiddle：

     function deletMany() { 

      var getManyNumber = parseInt(document.getElementById('setManyNumber').value); 

      for (var i = 0; i < getManyNumber; i++) { 
       try { 
        localStorage.removeItem('many' + i); 
       } catch (e) {     
       } 
      } 

      getMany(); 
     } 

     function getMany() { 
      var outputText = ''; 

      var getManyNumber = parseInt(document.getElementById('setManyNumber').value); 


      for (var i = 0; i < getManyNumber; i++) { 
       try { 
        var ot = localStorage.getItem('many' + i); 

        outputText += (ot) ? ot + '_' : i + " - no set <br/>"; 
       } catch (e) { 
        outputText += '|||' + i + '-' + e; 
       }

      var elm = document.getElementById('results'); 
      elm.innerHTML = outputText; 
     } 

     function setMany() { 

      var getManyNumber = parseInt(document.getElementById('setManyNumber').value); 

      for (var i = 0; i < getManyNumber; i++) { 
       localStorage.setItem('many' + i, "MANY" + i); 
      } 
     }

But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?" + i + '______________________________________________________________________ __________________________________________ ____________________________');
