無法將長json保存到Internet Explorer中的文件11

我正在嘗試將js應用程序的狀態（一個js對象）保存爲json字符串，以便稍後能夠加載該文件。無法將長json保存到Internet Explorer中的文件11

我使用此代碼

function SaveAsFile(t,f,m) { 
    try { 
    var b = new Blob([t],{type:m}); 
    saveAs(b, f); 
    } catch (e) { 
    window.open("data:"+m+"," + encodeURIComponent(t), '_blank',''); 
    } 
} 

function download(text) { 
    SaveAsFile(text,"filename.txt","application/json;charset=utf-8"); 
} 

$('#saveButton').on('click', function(e) { 
    download(JSON.stringify(appData)); 
});

現在奇怪的一部分：如果保存很短的JSON，如：

{ 
    "treeData": { 
    "id": "root", 
    "name": "Sicherung", 
    "data": { 
     "isLeaf": false, 
     "l": 0, 
     "A": 1, 
     "R": 0, 
     "Rsum": 0, 
     "I": 0, 
     "dUNormal": 0, 
     "danger": false, 
     "uRest": 24 
    }, 
    "children": [] 
    }, 
    "config": { 
    "voltage": 24, 
    "iFuse": 2, 
    "temperature": 30 
    } 
}

它完美的罰款。

但是，當我嘗試保存更長的JSON，如：

{ 
    "treeData": { 
    "id": "root", 
    "name": "Sicherung", 
    "data": { 
     "isLeaf": false,

     "A": 1, 
     "R": 0, 
     "Rsum": 0, 
     "I": 0, 
     "dUNormal": 0, 
     "danger": false, 
     "uRest": 24 
    }, 
    "children": [{

     },

    } 
}

IE11提示，我不能這個文件下載，由於安全設置。

在鉻短和長jsons字符串工作。不幸的是，我需要它在ie11上工作。

有沒有人有一個想法，如何解決這個問題？
哪個安全設置會導致此錯誤？
我可以用不同的方式/格式保存它嗎？

謝謝你的幫忙！

如果其他人有這個問題，這是我的解決方案。

function download(text) { 
    if (isIE()) { 
     var targetPath = $('#ieTargetPath').val(); 

     var fso = new ActiveXObject("Scripting.FileSystemObject"); 

     var s = fso.CreateTextFile(targetPath, true, true); 
     s.WriteLine(text); 
     s.Close(); 
    } else { 
     ... 
    } 
}

：

雖然我沒有找到實際的問題，我用不同的方法解決它
