Nevermind... Seems to only do it in debug mode.

New Post: Assertion failed

oobenoob — Tue, 21 May 2013 18:31:08 GMT

If I try the following...

try { js.Evaluate("sdF:[(L)"); }
catch (JavaScriptException e) { }
catch { }

Rather than the catch blocks detecting the rubbish script being evaluated, an "Assertion Failed" dialog appears, asking me to ignore/retry/abort.

New Post: variable declaration- problem with own datattype

furesoft — Tue, 21 May 2013 09:53:38 GMT

hello,
i have this classes:

public class SessionConstructor : ClrFunction
    {

        public SessionConstructor(ScriptEngine engine, string path) : base(engine.Function.InstancePrototype, "Session", new SessionInstance(engine.Object.InstancePrototype, path))
        {
        }

        [JSConstructorFunction()]
        public SessionInstance Construct(string path)
        {
            return new SessionInstance(this.InstancePrototype, path);
        }
    }

    public class SessionInstance : ObjectInstance
    {

        private Dictionary<string, object> _items = new Dictionary<string, object>();

        private string path;
        public SessionInstance(ObjectInstance prototype, string path) : base(prototype)
        {
            this.path = path;
            if (System.IO.File.Exists(path + "\\sessions")) {
                load();
            }
            this.PopulateFunctions();
        }

        [JSFunction(Name = "Add")]
        public void Add(string k, string v)
        {
            if (_items.ContainsKey(k)) {
                _items[k] = v;
            } else {
                _items.Add(k, v);
            }
            Save();
        }

        [JSFunction(Name = "Get")]
        public string Get(string k)
        {
            if (_items.ContainsKey(k)) {
                return _items[k];
            }
            return "";
        }

        private void Save()
        {
            StringBuilder c = new StringBuilder();

            foreach (object l_loopVariable in _items) {
                l = l_loopVariable;
                c.AppendLine(l.Key + "=" + l.Value.ToString);
            }

            System.IO.File.WriteAllText(path + "\\sessions", c.ToString());
        }

        private void load()
        {
            _items.Clear();

            foreach (object l_loopVariable in System.IO.File.ReadAllLines(path + "\\sessions")) {
                l = l_loopVariable;
                string k = l.Split("=")(0);
                string v = l.Split("=")(1);

                _items.Add(k, v);
            }

        }

        [JSFunction(Name = "Destroy")]
        public void Destroy()
        {
            System.IO.File.Delete(path + "\\sessions");
            _items.Clear();
        }

        {
            _items.Remove(k);
            Save();
        }

    }

and i will use this in javascript-code:

var session = new Session(AddinPath);
        
        session.Add("d",now);

but this make nothing.
please help me

New Post: Date parsing - doesn't like millsecond portion

paulbartrum — Thu, 16 May 2013 00:18:19 GMT

The example I provided does parse to a local time -- in Jurassic -- but it turns out this is a standard violation; ECMAScript 5.1 says that a missing time-zone should be interpreted as UTC. There is actually no standards-compliant way of parsing a local date & time, without explicitly specifying the time-zone (e.g. "2013-01-01T13:59:05.123+13:00"). In my defence, IE 10 and Firefox 21 both get this wrong (presumably because the local time-zone defaulting behaviour is more useful). Also, the ECMAScript standard conflicts with ISO 8601 which says that the absence of a time-zone should be interpreted as the local time-zone. Standards are great, huh?

Thanks. I wound up implementing the millisecond parsing for unstructured dates in our Jurassic build (in DateParser). The problem is I can't use ECMA string because they parse to UTC, and in our app we use relative time strings based the current user time zone among other things.

New Post: Debugging API that the host app can control?

Waqaar — Wed, 15 May 2013 09:45:34 GMT

If I have to support raising an event after each line of code execution in Java Script.

I have found this method "InlineSetPropertyValue" in class Jurassic.Library.ObjectInstance for simple line of execution but what will be the method for functions ?

SampleJs.js
var count = 1; // worked //Jurassic.Library.ObjectInstance InlineSetPropertyValue
myFunction();
function myFunction()
{

var t1 = "inside my function"; //dont work

}
var t2 = "end";

Thanks in advance.

paulbartrum — Wed, 15 May 2013 02:47:05 GMT

Correct, Jurassic doesn't support this type of date string (unstructured, with milliseconds). A quick check reveals that Chrome supports it in their javascript implementation, but Firefox and IE don't.

This is the equivalent ECMAScript standard date string, which works in all browsers:

new Date("2013-01-01T13:59:05.123")

New Post: Date parsing - doesn't like millsecond portion

joepotato — Wed, 15 May 2013 00:46:46 GMT

I am trying to parse a date string into a Date object.

This works: 1/1/2013 13:59:05
This doesn't: 1/1/2013 13:59:05.123

var d = new Date("1/1/2013 13:59:05.123");
var invalid = (d == null || isNaN(d.getHours()));
// invalid == true

paulbartrum — Mon, 13 May 2013 23:59:16 GMT

I think what is needed is a visual studio extension called a "expression evaluator". See here for sample code: http://msdn.microsoft.com/en-us/library/8fwk67y3(v=vs.90).aspx Fair warning though: implementing a expression evaluator is not for the faint of heart; it requires significant COM experience for one.

New Post: WebSocket

paulbartrum — Mon, 13 May 2013 23:51:23 GMT

Sorry, no, WebSockets are not part of javascript and therefore not part of Jurassic either.

ischyrus — Mon, 13 May 2013 19:49:20 GMT

I was wondering, does Jurassic handle\compile WebSocket calls and connections?

It is mentioned that Locals window and Watch window is not supported in Jurassic. How can I implement this ? I need to have full debugging support in Jurassic. Please guide me in this.
Thanks in advance,

New Post: doesn't Work on windows phone 7.1

mydiscogr — Tue, 07 May 2013 16:40:32 GMT

thanks for the answer :)

I've installed on vs2012 Express (windows 8)
installed jurassic via nuget

here's my last test:

namespace TestJavascript
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            var engine = new Jurassic.ScriptEngine();
            engine.Execute("var k = 1;");
        }
    }
}

I get this exeception:

on Execute : "Could not load type 'System.Runtime.Serialization.ISerializable' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'."

thanks again

What exception are you getting? Have you seen this page? https://jurassic.codeplex.com/wikipage?title=Using%20the%20console%20API&referringTitle=Documentation

mydiscogr — Mon, 06 May 2013 08:58:25 GMT

Hi I've installed Jurassic on app via nuget and I loaded simple example:

var engine = new Jurassic.ScriptEngine();
engine.Execute("console.log('testing')");

just like Jurassic Docs, but doesn't works at all, Exception on deserialize, I've include some libs as reference like System.Serialization ecc.

I've used VS2012 Express edition, Nuget (last one), and a new 7.1 project...

please if U can help me :)

String literals cannot contain newlines in javascript. The easiest way to do what you want is this:

var script = @"
    function Hello() {
    }";
var engine = new ScriptEngine();
engine.SetGlobalValue("script", script);

New Post: Where's the silverlight console gone from this site?

paulbartrum — Tue, 30 Apr 2013 00:11:07 GMT

I think CodePlex is migrating to use HTTPS, which meant the embedded silverlight control wouldn't load. I've changed the page so it should work for both HTTP and HTTPS now.
