i want to create a text file from a string. currently i am using a function which takes an array and makes it into a string then using that string i want to create a local text file the user downloads.
i have tried using this method

   function createFile(){ //creates a file using the fileLIST list 

    var output= 'Name t Statusn'+ fileLIST[0][0].name+'t'+fileLIST[0][1]+'n';

    var Previous = fileLIST[0];

    for (var i=1; i<fileLIST.length; i++)

        if (fileLIST[i][1] =='none' || fileLIST[i][1] == Previous[1])

            continue

        else {

            Previous = fileLIST[i]

            output = output + fileLIST[i][0].name +'t'+fileLIST[i][1] + 'n';}



    window.open(data:text/json;charset=utf-8, + escape(output));//should create file

    display();  }

i am using chrome as my browser. also i would prefer JS or HTML5 answer.

thank you in advance

i ended up using this code instead. it creates a link to download the url of the file.

     window.URL = window.webkitURL || window.URL;

    window.BlobBuilder = window.BlobBuilder || window.WebKitBlobBuilder ||       window.MozBlobBuilder;

    file = new WebKitBlobBuilder();

    file.append(output); 

    var a = document.getElementById(downloadFile);

    a.hidden = '';

    a.href = window.URL.createObjectURL(file.getBlob('text/plain'));

    a.download = 'filename.txt';

    a.textContent = 'Download file!';

}

also this way adds less to the website making it a lighter website for slow connections.
my html has a empty div in which this appends to.

   <div class ='paginationLIST' id='pagination'></div>
