Monkey Forums/Monkey Code/HTML5 XMLHttpRequest Wrapper

i've created a small XMLHttpRequest Wrapper. It works with Firefox, Chrome and IE. I have not tested other browsers yet.

Demo: http://sedm.de/monkey/nettest/
Module: http://sedm.de/monkey/nettest/jnet.zip

Sample:

Strict

Import mojo
Import jnet

Class myApp extends App
	Field http:XMLHttpRequest
	Field response:String
	
	Method OnCreate:Int()
		response = ""
		http = New XMLHttpRequest()
		http.open("http://sedm.de/pub/ip.php")
		http.send()
		
		SetUpdateRate(30)
		
		Return 0
	End
	
	Method OnUpdate:Int()	
		response = http.responseText()		
		Return 0
	End
	
	Method OnRender:Int()
		Cls
		DrawText("sedm.de says: " + response, 10, 10)
		Return 0
	End
End

Function Main:Int()
	New myApp
	Return 0
End

Methodlist of the class "XMLHttpRequest":

Method open:void(url:String, type:String = "GET", async:Bool = true, userName:String = "", password:String = "")
Method send:Void(body:String = "")
Method state:String()
method status:String()
Method statusText:String()
Method responseXML:String()
Method responseText:String()
Method abort:Void()
Method getResponseHeader:String(header:String)
Method getAllResponseHeaders:String()
Method setRequestHeader:Void(header:String, value:String)

have fun!

Changes:
the getter methods are now fields, like in the original XMLHttpRequest object.

Additions:
jNet now has a Flash-Target. Flash Example at : http://sedm.de/monkey/nettest/MonkeyGame.html

jNet is abandoned, use utils instead: http://www.sedm.de/monkey/utils.zip

1. create a new Object from XMLHttpRequest

Local xhr:XMLHttpRequest = new XMLHttpRequest()

2. open a HTTP Connection to a URL

xhr.open("google.com", "GET") ' GET is default, you can also use "POST"

3. send the request

xhr.send()

3. wait for the answer

If xhr.responseText.Length() doAnythingWithTheAnswer()

on Android you must set the correct permission to access the internet! Remind that not all ISP's allows XMLHttpRequest. preferably you should use it on the same Domain to get Highscores, load Data (like Leveldata) etc.

Thanks for providing this, but JFYI I noticed a very slight issue.

The equal sign was missing below, and the compiler was complaining about missing identifier for the function. I'm using v53.

#if TARGET "html5"
	Function Include:Void(url:String) = "utils_include"
#EndIf

Do you mind to please check & update it?

Also I feel a bit silly, but though I comment out the above, and tried your original jnet code, I could never get a response in either case. All I could get was 'undefined' as a response. Do you have a suggestion? Thanks.

Sorry about the double post - not sure how it happened. I updated my original post a couple of times to include code formatting, but it seems to have duplicated my post after that.
