hi,
i need to create a javascript or asp function that allow user to download a file he selected.

Suppose i have this table where I list files users can download  and a button
which allows user to download that file

<td> Nome file </td>
<td><input type ="Button" value ="Scarica"
onclick="download('myFileNamePath');"></td>

ok I need to let user download the file he selected by the function download
Solution can be made both by javascript or by javascript + asp.

Now I tried the second solution with no success: I open an asp file
where I send by get the filename path and add as the lines:

  response.ContentType = "application/octet-stream"
  response.AddHeader "Content-Disposition", "attachment; filename=" & request("file") & ";"

where 'file' is the file I want to let user download

but the IE always download the default asp page ... :-((((

My idea is simply to simulate the 'Save as' browser command
and open a window to ask user where he wants to save the file.

any idea or suggestion would be appreciated.

Thx

<script language=javascript>
function download(locate){
window.open(locate)
}
</script>


<td> Nome file </td>
<td><input type ="Button" value ="Scarica"
onclick="download('myFileNamePath.zip');"></td>


make sure your file is of correct name,

.zip will automatically send to download.

maybe i didn't explain well my problem...

I need a function, in asp or javascript, that let user download a file selected by an input button. This file may be a text file or a zip file or a pdf file.
The list of the files users can download is dinamically generated.

window.open opens file in a different window....
I need a function that opens a window to the user so he can choose where
to save the file he wants to download.
I need to bypass the explorer setting that decides if the file has to be downloaded or opened in the window.

In other words i need to simulate the 'saveas' command button
generated by a right-click on a file listed in the html page.

thanks
