How do I read from a text file using JavaScript in an ASPX page?

I am trying to read the contents of a text file (it could be an XML file if need be, any type of file) into the JS on the web page so that I can compare user input against a list of allowed inputs.  Can anyone throw up some code as to how to do this?  I'm not really too strong on JS, I'm more of a VBS kinda guy, but this whole site is already written in JS.

Here's what I've written so far, please feel free to hack it up/make it work by any means possible.

function check(Name){
	var data = "";
	var fileObj = new ActiveXObject("Scripting.FileSystemObject");
	if (fileObj.FileExists("C:\Inetpub\wwwroot\Citrix\XenApp\auth\clientscripts\names.txt")) {
		var f = fileObj.GetFile("C:\Inetpub\wwwroot\Citrix\XenApp\auth\clientscripts\name.txt",1);
		var ts = f.OpenAsTextStream(1,0);
		while (!f.AtEndOfStream) {
			data = ts.ReadLine();
			if (data == Name) {
				return true;
	return false;
