The following code should work

from browser import window
from javascript import JSConstructor

xhttp = JSConstructor(window.XMLHttpRequest)()

Great, if it is possible to have a demo it would be great.

We could add this to the brython gallery or to the 'brython in the wild' wiki (https://github.com/brython-dev/brython/wiki/Brython%20in%20the%20wild).

Uff, I have not idea about that. I don't know if it uses chrome, the android browser, other stuff under the hood.

I tried the following example (http://jsfiddle.net/23u56ct9/) on my android (v4.4.4) with chrome and it doesn't work but it works with FF on the same mobile. But with the mobile I can't debug anything.

I can't dive more now (I'm working).

Did you imported window?

from browser import window

if you use window.XMLHttpRequest you should have similar control as you are using the JS object directly...

look if i code that it work :

function Get (emailval, passwordval) {

var req = new XMLHttpRequest();

 loadingdiv = document.getElementById('loading');

loadingdiv.style.display = "block";

req.open("GET", 'xxxxxxxxxxxx + email + password , false);

req.onreadystatechange = function (aEvt) {

  if (req.readyState == 4) {

     if(req.status == 200)

   document.getElementById("resultat").innerHTML=  req.responseText '),

    

     else

      document.getElementById("resultat").innerHTML="Erreur pendant le chargement de la page",

      alert(req.responseText) 

    

}

else {

}

};

req.send(null);

// body...  

}

brython code

from browser import alert, window
from javascript import JSConstructor

rectangle = JSConstructor(window.Get)
Get(password, email)

but this code doesent work

This may be related to issue #373 : for some browsers, XMLHttpRequest is not a function, and in this case
using JSConstructor fails. You should try to use the Brython ajax module instead of window.XMLHttpRequest

dans ce cas il faut que j'installe le server brython pour que l'ajax fonctionne  vue que je suis en local sur l'application ?

[eric cuver]

in this case I have to install the server Brython works for the ajax view I am local to the web application?

Non, par contre il faut intégrer Brython par <script src="brython_dist.js"> pour améliorer le chargement des modules, dont ajax.

[eric cuver]

Il existe une version mimifier de ce brython JS car il gros et lent au chargement

[eric cuver]

je pense que je vais plutot utilise JQUERY  avec le POST ET GET

comme ça 

jq = window.jQuery.noConflict(True)

jq= jq("div")
