I'm planning on using JavaScript to enter an informatics competition (BIO) tomorrow. However, I can't rely on the examiner having a browser with a decent JavaScript engine, so I was hoping to use Microsoft's JScript instead.
However, the documentation is, quite frankly, crap. Can someone post some example code that reads in a line of text, calls foo(string) on it, and echos the output to the command line?
Similarly, how do I actually run it? Will wscript.exe PATH_TO_JS_FILE do the trick?
If you're using the command-line, I'd execute the script using CSCRIPT.EXE.
ie: CSCRIPT.EXE myscript.js
This is because WScript.Echo from WSCRIPT will create a dialog box and from CSCRIPT outputs a line to the console. Run this in a command window (CMD).
Reading a line from console into variable:
var x = WScript.StdIn.ReadLine();
Where StdIn is a TextStream object. There is also an StdOut which can be used in place of WScript.Echo()...
Writing the output of foo(x) to console: (must run under CSCRIPT)
WScript.Echo(foo(x));
You can use the WScript object to determine which engine you are running under, there's a question/answer for that (VBScript, but uses the same objects under JScript) here.
If you want to be sure your program only runs in the command line, you may use the WScript.StdIn and WScript.StdOut objects/properties:
var myString = WScript.StdIn.ReadLine();
WScript.StdOut.WriteLine(myString);
and run it with cscript.exe. But if you want it to be a GUI program, it is a bit more difficult considering that JScript doesn't have a native InputBox function like VBScript. However, as described here we may use Windows Script Host (WSH). Create a .wsf file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<job id="testJScriptInputBox">
<script language="VBScript">
<![CDATA[
Function WSHInputBox(Message, Title, Value)
WSHInputBox = InputBox(Message, Title, Value)
End Function
]]>
</script>
<script language="JScript">
<![CDATA[
var vbOKOnly = 0; // Constants for Popup
var vbInformation = 64;
var title = "InputBox function for JScript";
var prompt = "Enter a string: ";
var WshShell = WScript.CreateObject("WScript.Shell");
var result = WSHInputBox(prompt, title, "New York");
if (result != null)
{ // Cancel wasn't clicked, so get input.
var intDoIt = WshShell.Popup(result,
0,
"Result",
vbOKOnly + vbInformation);
}
else
{ // Cancel button was clicked.
var intDoIt = WshShell.Popup("Sorry, no input",
0,
"Result",
vbOKOnly + vbInformation);
}
]]>
</script>
</job>
and run it with either cscript.exe or wscript.exe. Alternatively, you could also use HTML Application (HTA) to create more elaborate GUIs.

I want to identify few properties during my run and form a json object which I would like to write to a ".json"file and save it on the disk.
var target = UIATarget.localTarget();
var properties = new Object();
var jsonObjectToRecord = {"properties":properties}
jsonObjectToRecord.properties.name = "My App"
UIALogger.logMessage("Pretty Print TEST Log"+jsonObjectToRecord.properties.name);
var str = JSON.stringify(jsonObjectToRecord)
UIALogger.logMessage(str);
// -- CODE TO WRITE THIS JSON TO A FILE AND SAVE ON THE DISK --
I tried :
// Sample code to see if it is possible to write data
// onto some file from my automation script
function WriteToFile()
{
set fso = CreateObject("Scripting.FileSystemObject");
set s = fso.CreateTextFile("/Volumes/DEV/test.txt", True);
s.writeline("HI");
s.writeline("Bye");
s.writeline("-----------------------------");
s.Close();
}
AND
function WriteFile()
{
// Create an instance of StreamWriter to write text to a file.
sw = new StreamWriter("TestFile.txt");
// Add some text to the file.
sw.Write("This is the ");
sw.WriteLine("header for the file.");
sw.WriteLine("-------------------");
// Arbitrary objects can also be written to the file.
sw.Write("The date is: ");
sw.WriteLine(DateTime.Now);
sw.Close();
}
But still unable to read and write data to file from ui automation instruments
Possible Workaround ??
To redirect to the stdout if we can execute a terminal command from my ui automation script. So can we execute a terminal command from the script ?
Haven't Tried :
1. Assuming we can include the library that have those methods and give it a try .
Your assumptions are good, But the XCode UI Automation script is not a full JavaScript.
I don't think you can simply program a normal browser based JavaScript in the XCode UI Automation script.
set fso = CreateObject("Scripting.FileSystemObject");
Is not a JavaScript, it is VBScript which will only work in Microsoft Platforms and testing tools like QTP.
Scripting.FileSystemObject
Is an ActiveX object which only exists in Microsoft Windows
Only few JavaScript functions like basic Math, Array,...etc..Are provided by the Apple JavaScript library, so you are limited to use only the classes provided here https://developer.apple.com/library/ios/documentation/DeveloperTools/Reference/UIAutomationRef/
If you want to do more scripting then Try Selenium IOS Driver http://ios-driver.github.io/ios-driver/
Hey so this is something that I was looking into for a project but never fully got around to implementing so this answer will be more of a guide of what to do than step by step copy and paste.
First you're going to need to create a bash script that writes to a file. This can be as simple as
!/bin/bash
echo $1 >> ${filename.json}
Then you call this from inside your Xcode Instruments UIAutomation tool with
var target = UIATarget.localTarget();
var host = target.host();
var result = host.performTaskWithPathArgumentsTimeout("your/script/path", ["Object description in JSON format"], 5);
Then after your automation ends you can load up the file path on your computer to look at the results.
EDIT: This will enable to write to a file line by line but the actual JSON formatting will be up to you. Looking at some examples I don't think it would be difficult to implement but obviously you'll need to give it some thought at first.
I try to schedule a script using the 'Scheduled Tasks' in ML8. The documentation explains this a bit but only for xQuery.
Now I have a JavaScript file I'd like to schedule.
The error in the log file:
2015-06-23 19:11:00.416 Notice: TaskServer: XDMP-NOEXECUTE: Document is not of executable mimetype. URI: /scheduled/cleanData.js
2015-06-23 19:11:00.416 Notice: TaskServer: in /scheduled/cleanData.js [1.0-ml]
My script:
/* Scheduled script to delete old data */
var now = new Date();
var yearBack = now.setDate(now.getDate() - 65);
var date = new Date(yearBack);
var b = cts.jsonPropertyRangeQuery("Dtm", "<", date);
var c = fn.subsequence(cts.uris("", [], b), 1, 10);
while (true) {
var uri = c.next();
if (uri.done == true){
break;
}
xdmp.log(uri.value, "info"); // log for testing
}
Try the *.sjs extension (Server-side JavaScript).
The *.js extension can be used for static JavaScript resources to return to the client instead of executed on the server.
Hoping that helps,
I believe that ehennum found the issue for you (the extension - which is what the mime-type error is complaining about.
However, on the same subject, not all items in ML work quite as you would expect for Serverside Javascript. For example, using sjs as a target of a trigger is (or recently) did not work. So for things like that, it is also possible to wrap the sjs call inside of xqy using xdmp-invoke.
I am currently writing a JavaScript script for the Microsoft JScript Runtime Environment. It's not in a browser, but rather going to be run more like a SysAdmin would use VBScript. I've written a lot of code, and while some of it is specific for what needs to be accomplished, a majority of it is supporting framework for the script to do what it needs to do. I'd like to use this sum of code in other future scripting adventures, but as to my current knowledge, I would have to copy and paste these mini-libraries over and over again, and well, that's just an update nightmare for one and two, it's inefficient. I know it's possible to dynamically load JS when I have a window or document, I know it's possible to require() JS files in Node.js, but is this possible in the raw JScript Runtime for MS?
Look into the Windows Script File (*.wsf) format. One of its features is to allow for includes like you're describing. An example taken from the linked documentation:
<job id="IncludeExample">
<script language="JScript" src="FSO.JS"/>
<script language="VBScript">
' Get the free space for drive C.
s = GetFreeSpace("c:")
WScript.Echo s
</script>
</job>
where "FSO.JS" contains the JScript library.
Assuming your talking about the WSH, you can load a file and eval the contents, which is much the same as including it.
var incfso=new ActiveXObject("Scripting.FileSystemObject");
include = function(x) {
eval(incfso.OpenTextFile(x,1).ReadAll());
}

I couldn't find a global object like "window" for jscript, but you can sort of create one.
var host = this;
var test = "hello-world";
var messagebox = new ActiveXObject("wscript.shell");
if (host.test) {
messagebox.Popup("host.test exists, value = " + host.test);
} else {
messagebox.Popup("host.test does not exist.");
}
I think "host" should now effectively be the global object. (the example works for me anyway)
EDIT: I'm trying to read all the files in a specific folder and list the files in there, not read the content of a specific file. I just tried to simply create an FileSystemObject and it doesn't do anything either. I show an alert (which pops up) beforfe making the FileSystemObject, and one after it (which isn't shown). So the problem is in simply creating the object.
Original:
I am trying to read all the files in a folder by using JavaScript.
It is a local HTML file, and it will not be on a server, so I can't use PHP I guess.
Now I'm trying to read all the files in a specific given folder, but it doesn't do anything on the point I make a FileSystemObject
Here is the code I use, The alert shows until 2, then it stops.
alert('1');
var myObject, afolder, date;
alert('2');
myObject = new ActiveXObject("Scripting.FileSystemObject");
alert('3');
afolder = myObject.GetFolder("c:\\tmp");
alert('4');
date = afolder.DateLastAccessed;
alert("The folder"+name+" is a temporary folder.");
Am I doing this the right way?
Thanks!
The method I found with a Google search uses HTML5 so if you are using a modern browser you should be good. Also the tutorial page seems to check if the browser you are using supports the features. If so you should be good to follow the tutorial which seems pretty thorough.

This solution only works on IE11 or older since it is MS based
<script type="text/javascript">
var fso = new ActiveXObject("Scripting.FileSystemObject");
function showFolderFileList(folderspec) {
var s = "";
var f = fso.GetFolder(folderspec);
// recurse subfolders
var subfolders = new Enumerator(f.SubFolders);
for(; !subfolders.atEnd(); subfolders.moveNext()) {
s += ShowFolderFileList((subfolders.item()).path);
}
// display all file path names.
var fc = new Enumerator(f.files);
for (; !fc.atEnd(); fc.moveNext()) {
s += fc.item() + "<br>";
}
return s;
}
function listFiles() {
document.getElementById('files').innerHTML = showFolderFileList('C:');
}
</script>
<input type='button' onclick='listFiles()' value='List Files' />
<div id="files" />
I have a script CustomAction (Yes, I know all about the opinions that say don't use script CustomActions. I have a different opinion.)
I'd like to run a command, and capture the output. I can do this using the WScript.Shell COM object, then invoking shell.Exec(). But, this flashes a visible console window for the executed command.
To avoid that, I understand I can use the shell.Run() call, and specify "hidden" for the window appearance. But .Run() doesn't give me access to the StdOut of the executed process, so that means I'd need to create a temporary file and redirect the exe output to the temp file, then later read that temp file in script.
Some questions:
is this gonna work?
How do I generate a name for the temporary file? In .NET I could use a static method in the System.IO namespace, but I am using script here. I need to insure that the use has RW access, and also that no anti-virus program is going to puke on this.
Better ideas? I am trying very hard to avoid C/C++.
I could avoid all this if there were a way to query websites in IIS7 from script, without resorting to the IIS6 Compatibility pack, without using .NET (Microsoft.Web.Administration.ServerManager), and without execing a process (appcmd list sites).
I already asked a separate question on that topic; any suggestions on that would also be appreciated.
Answering my own question...
yes, this is going to work.
Use the Scripting.FileSystemObject thing within Javascript. There's a GetTempName() method that produces a file name suitable for temporary use, and a GetSpecialFolder() method that gets the location of the temp folder. There's even a BuildPath() method to combine them.
so far I don't have any better ideas.
Here's the code I used:
function GetWebSites_IIS7_B()
{
var ParseOneLine = function(oneLine) {
...regex parsing of output...
};
LogMessage("GetWebSites_IIS7_B() ENTER");
var shell = new ActiveXObject("WScript.Shell");
var fso = new ActiveXObject("Scripting.FileSystemObject");
var tmpdir = fso.GetSpecialFolder(SpecialFolders.TemporaryFolder);
var tmpFileName = fso.BuildPath(tmpdir, fso.GetTempName());
var windir = fso.GetSpecialFolder(SpecialFolders.WindowsFolder);
var appcmd = fso.BuildPath(windir,"system32\\inetsrv\\appcmd.exe") + " list sites";
// use cmd.exe to redirect the output
var rc = shell.Run("%comspec% /c " + appcmd + "> " + tmpFileName, WindowStyle.Hidden, true);
// WindowStyle.Hidden == 0
var ts = fso.OpenTextFile(tmpFileName, OpenMode.ForReading);
var sites = [];
// Read from the file and parse the results.
while (!ts.AtEndOfStream) {
var oneLine = ts.ReadLine();
var line = ParseOneLine(oneLine);
LogMessage(" site: " + line.name);
sites.push(line);
}
ts.Close();
fso.DeleteFile(tmpFileName);
return sites;
}
