I am trying to download file using javascript. I am successfull in downloading the file using following code but when I Open the file the content is unreadble. I am not getting where am i going wrong. can anyone guide me on this to fetch the file with readable content ?

    function SaveToDisk(fileURL, fileName) {
        debugger;
        // for non-IE
        if (!window.ActiveXObject) {
            var save = document.createElement('a');
            save.href = fileURL;
            save.target = '_blank';
            save.download = fileName || 'unknown';

            var evt = new MouseEvent('click', {
                'view': window,
                'bubbles': true,
                'cancelable': false
            });
            save.dispatchEvent(evt);

            (window.URL || window.webkitURL).revokeObjectURL(save.href);
        }

        // for IE < 11
        else if (!!window.ActiveXObject && document.execCommand) {
            var _window = window.open(fileURL, '_blank');
            _window.document.close();
            _window.document.execCommand('SaveAs', true, fileName || fileURL)
            _window.close();
        } 
}

  • Can you set this up in a fiddle or JSBin? Typically, for file downloads from JS, you need to build a blob and use a data: url. – Johannes Jander Feb 17 '16 at 10:18
