Saving a CSV file using execcommand()

Hi,

Right now, I'm trying to get a SaveAs dialog box to display and save a CSV file when they click on a link.

I have been using the execcommand() at many unsuccessful attempts at this.

My question is, is it necessary to for the contents of the CSV file to be within the page of the JavaScript itself before I could use execcommand() to prompt the user to save it?

Thanks.

Hmmm..I see the problem.

I'm not sure if it's possible. Can you just have a link to the file, and tell the user to right click it and save it that way?

My script is very simple, essentially:

function ExportCsv()
{
     document.execCommand('SaveAs', true, <url of the csv file>);
}

<a href="#" onClick="ExportCsv();"></a>

Yes, the page has to be loaded.

You can try putting the page in a hidden Iframe:

<iframe name=iframeName style="display:none;" src=<url of the csv file>></iframe>

And then:

function ExportCsv()
{
     window.frames["iframeName"].document.execCommand('SaveAs', true, <url of the csv file>);
}

I tried the code above and it doesn't work.  I am, however, setting the url of the csv file in my code for both the iframe and the JavaScript function.

When I click on my export link, it just brings me to a different page, instead of prompting me with the SaveAs dialog box.

This code works for me:

<script>
function ExportCsv(){
  window.frames["iframeName"].document.execCommand("SaveAs",true);
}
</script>

<a href="#" onclick="ExportCsv();">Export</a>

<iframe style="display:none;" name=iframeName src=test.htm></iframe>

Perhaps it's different for CSV files?

I did a test using .txt and .htm/l files.  They work for both, but it doesn't work for the type of file that I'd like to save.  Would you be able to suggest anything else?  I understand that execcommand() is also an IE thing.

I have it like that, but it's an added step in the workflow, so it would be preferable if I could have them left-click and the SaveAs dialog box come up right away.

I'll experiment with Response.content-type and IIS settings and such to see what I could come up with.  Thank you for your help.
