Is it possible to create files on a webserver by JavaScript?
Also if you can, can you write to them etc?
I mean this so when the JS is ran it creates the file etc.
I know you can do this with more powerful scripting languages, but I'm just trying to find out JS's ability.
create a link on a web page. when the user clicks on it it prompts the user for a file name, then created the file on the serverside.

<script language="VB" runat="server">
Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim strFileName As String = funcParam.Value
'custom code to create a text file
End Sub
</script>
<html>
<head>
<script language="JavaScript">
//ask for user input and then create file
function CreateFile() {
//get filename from the user
var fileName = prompt('Type the name of the file you want to create:','');
//if the user clicks on OK and if they have entered something
if ((fileName) && (fileName!="")) {
//save the filename to the hidden form field 'funcParam'
document.forms['myForm'].elements['funcParam'].value = fileName;
//call the postback function with the right ID
__doPostBack('CreateFile','');
}
}
</script>
</head>
<body>
<form runat="server" id="myForm">
Create Text file
<asp:linkbutton id="CreateFile" runat="server" onclick="CreateFile_Click" />
<input type="hidden" runat="server" id="funcParam">
</form>
</body>
</html>

ReLik: With just JS, no you cannot create server-side files or write to files.
meister, please note that your code will only run on Windows (since it uses ActiveX) and Internet Explorer (since it uses VBScript). Otherwise, yes, it should work.
