Trying to use Javascript to download a string variable created in Classic ASP

Viewed 47

I have a classic ASP that I have to update because of changes in Excel(No longer opens tables). In Classic asp, I have recreated my report code to create the data as a string variable containing comma separated values. I need to make that available to download to the customer. I am using a javascript solution that I found on this site. (There is size limitation using Classic ASP to download, not to mention browser compatibility issues).

Here is the Comman seperated string variable:

'Classic ASP
    sCSV = Header
    sCSV = sCSV & BODY

Here is how I am getting that string variable to the HTML section:

 // HTML section    
 <body>
 <input type="hidden" name="sCSV" value="<%=sCSV %>" /> 

Here is how the customer selects the download and calls the Javascript function:

 <p align="left" id="buttonarea">
 <a onclick="CSVExport(sCSV)" class="buttonlink">Save       Report<br /> as CSV for Excel</a>
 </p>

and here is the Javascript function:

 // Javascript section
    function CSVExport(Source) { 
    alert(Source);
    var csv = Source ;
    var downloadLink = document.createElement("a");
    var blob = new Blob(["\ufeff", csv]);  //Fails at this line
    var url = URL.createObjectURL(blob);
    downloadLink.href = url;
    downloadLink.download = "Report.csv";
    document.body.appendChild(downloadLink);
    downloadLink.click();
    document.body.removeChild(downloadLink);

I believe its failing at this line: var blob = new Blob(["\ufeff", csv]);

If I do an alert on sCSV, it says 'Object', which leads me to believe that its not getting a string, but an empty object.

My system will not allow me to use the F12 console to troubleshoot (Its locked out for security). Any help would be appreciated !
