Answer 1

The document.execCommand('saveas') functionality is supported only in IE and is not supported in Chrome and Mozila .

You can force the SaveAs using http header . You have to include the following header in HTTP response of the file to be downloaded:

Content-Disposition: attachment; filename="<file name.ext>"

Where <file name.ext> is the filename you want to appear in SaveAs dialog (like finances.xls or mortgage.pdf ) - without < and > symbols.
