    Par défaut Datarequestor [mise a jour importante]
    Bonjour, si vous connaissez un peu la librairie datarequestor, vous devez savoir qu'elle permet de faire des échanges Ajax trés facilement sans grande connaissance du javascript.
    Personnellement, je l'utilise dans un trés gros projet. (au début, par manque de connaissance javascript)
    Mais au fur et a mesure, la librairie a révélé ses faiblesses.
    Elle ne permet pas l'envoie d'un fichier par exemple. (problème pas résolu a ce jour.)
    Par contre d'autre problème, comme l'encodage des "+" faisait cruellement défaut.
    Je vous propose donc un lien de téléchargement de cette nouvelle version qui corrige quelques problèmes.
    n'hésitez pas a consulter le site, de son créateur pour plus d'information sur son utilisation.

    lien : http://github.com/Airod/datarequestor/downloads
    et : http://mikewest.org/2006/03/datarequestor

    voilà, si ca peut aider quelqu'un!

    Excellent !

    Merci airod pour le lien.
    J'utilisais encore un truc "fait main" pour ça. Je pense que c'est mieux d'utiliser une solution maintenue.

    Bonne journée,
    Thomas.

    Voilà deux ans que je galère, et j'ai enfin trouvé la solution.
    Il y a un problème majaure avec DataRequestor, c'est l'impossibilité du chargement de script js contenu dans la réponse.

    J'ai mis du temps car j'ai voulu entre temps migrer de DataRequestor vers Jquery.ajax.
    Seulement là ou Jquery résoud le problème du chargement des scripts contenu dans la réponse ajax, je me retrouve avec de gros problème d'encodage et au final plus de problèmes à résoudre. Je suis condamné a concerver DataRequestor pour gérer les requêtes ajax dans mon projet (Gros très gros projet).
    Alors voici comment j'ai résolu le manque dans DataRequestor.
    je déclenche sur la callback (onload) de DataRequestor l'appel a cette fonction :
    Code : Sélectionner tout - Visualiser dans une fenêtre à part

    function addScript(data,obj)
     {
     
    	 var reg=RegExp('<script>(.*)</script>','gi');
    	 var ldata=data.match(reg);
    	 var scriptString='';
     
    	 for (var i=0;i<ldata.length;i++)
    	 {
     
     
    			scriptString+=ldata[i].replace('<script>','').replace('</script>','')+';';
     
     
     
    	 }	
     
    	 var fileref=document.createElement('script')
    		fileref.setAttribute("type","text/javascript")
    		fileref.innerHTML=scriptString;
    		obj.appendChild(fileref);
    }
    Elle n'est peut être pas super propre, mais elle fonctionne impec.

    Bonjour, voilà j'ai fait quelque chose de plus propre. J'ai intégré le chargement des javascripts contenus dans la réponse ajax, directement dans DataRequestor.

    voici le nouveau code :

     *    DataRequestor Class v: 1.8.2 - June, 2011
     *
     *	      Copyright 2007 - Mike West - http://mikewest.org/
     *
     *        This software is licensed under the CC-GNU LGPL <http://creativecommons.org/licenses/LGPL/2.1/>
     *
     *        This class wraps the XMLHttpRequest object with a friendly API
     *        that makes complicated data requests trivial to impliment in
     *        your application.
     *
     *        USAGE:
     *            ----
     *            BASIC
     *            To instantiate the object, simply call it as a constructor:
     *
     *                var req = new DataRequestor();
     *
     *            Once you have the object instantiated, your usage will depend
     *            on your needs.  
     *
     *			  RETURNING TEXT
     *            If you want to grab data, and shove it wholesale into an element 
     *            on the page (which I do 90% of the time), then tell the DataRequestor
     *            object where to stick the info by passing setObjToReplace an
     *            element ID or object reference, and call getURL to complete the
     *            process:
     *
     *                req.setObjToReplace('objID');
     *                req.getURL(url);
     *
     *
     *            RETURNING A DOM OBJECT
     *            By default, the contents of the requested file will be passed in as
     *            plaintext, which can be simpler to work with than a real DOM object.
     *            If you'd like a DOM object to work with, then call getURL with
     *            _RETURN_AS_DOM as the second argument:
     *
     *                req.getURL(url, _RETURN_AS_DOM);
     *
     *            To avoid irritating problems, make sure you're sending a Content-type header
     *            of "text/xml" when you'd like your data processed as a DOM object.  IE gets
     *            confused otherwise.
     *
     *            RETURNING A JSON OBJECT
     *            If you've no idea what JSON is, visit http://www.json.org/
     *
     *            To get a JavaScript object back from DataRequestor, call getURL with
     *            with _RETURN_AS_JSON as the second parameter.
     *
     *                req.getURL(url, _RETURN_AS_JSON);
     *
     *            This, of course, assumes that you've generated a JSON string correctly
     *            at the URL you've requested.
     *            ----
     *            ARGUMENTS
     *
     *            To pass in GET or POST variables along with your request, use the
     *            addArg method:
     *
     *                req.addArg(argType, argName, argValue);
     *                e.g.
     *                req.addArg(_GET, "argument_number", "1");
     *
     *            addArg will automatically call escape() on the name and value to
     *            ensure they are URL escaped correctly.
     *            
     *            ARGUMENTS FROM A FORM
     *
     *            To pass in all the arguments from a form, use the `addArgsFromForm`
     *            method.  This will automatically call `addArg` on each of the form
     *            elements using the `method` attribute of the form to set the request 
     *            method for the arguments.  Each form element *must* have an ID for this
     *            method to function correctly.
     *
     *                req.addArgsFromForm(formID);
     *                e.g.
     *                req.addArgsFromForm("myFormName");
     *            ----
     *            EVENT HANDLERS
     *
     *                ON LOAD
     *
     *                To take action when the data loads successfully, set onload to a function that
     *                takes two arguments: data, and obj.  This will be called upon successful retrieval
     *                of the requested information, and will be passed the data retrieves and the object
     *                that will be replaced (or null if no replacement has been requested).
     *
     *                    req.onload = function (data, obj) {
     *                        alert("Callback handler called with the following data: \n" + data);
     *                    }
     *
     *                The first parameter (`data`) will be one of three things:
     *                    - text:  If getURL was called without a second argument, or _RETURN_AS_TEXT,
     *                      then `data` contains the raw text returned by the page that you loaded.
     *                    
     *                    - DOM object: If getURL was called with _RETURN_AS_DOM as the second argument, then
     *						`data` contains a DOM object, with blank whitespace nodes removed in order to 
     *                      provide a consistant experience between browsers that support the DOM standard
     *                      and IE.
     *
     *                    - JavaScript object: If getURL was called with _RETURN_AS_JSON as the second argument,
     *                      then `data` contains a JavaScript object generated from the JSON text that was returned
     *                      by the page you loaded.
     *
     *                ON REPLACE
     *                
     *                If you requested a replacement by setting an `objToReplace`, then this handler will
     *                be called directly after the replacement occurs, and will be passed the same variables
     *                as the `onload` method.
     *
     *                    req.onreplace = function (data, obj) {
     *                        alert("Callback handler called with the following data: \n" + data);
     *                    }
     *
     *                ERROR HANDLING
     *
     *                If the request fails, the XMLRequestor object defaults to simply throwing
     *                an error.  If that's not a great solution for you, then assign a function
     *                to onfail that accepts a single variable: the XMLHttpRequest status
     *                code.  If the status returned is "-1", then DataRequester encountered
     *                an error it didn't know what to do with.  In this case, it will pass a
     *                second argument: the text of the thrown error.  Do with it what you will:
     *
     *                    req.onfail = function (status) {
     *                        alert("The handler died with a status of " + status);
     *                    }
     *
     *                PROGRESS
     *
     *                In Mozilla, it's possible to dynamically retrieve the amount of data that
     *                has been downloaded so far.  If you'd like to take an action on that data
     *                (e.g. set up some sort of progress bar) then set an onprogress handler that
     *                accepts two arguments, currentLength and totalLength.  Curiously enough,
     *                these arguments will be populated with the current amount of data that's been
     *                retrieved and the total size (or -1 if it can't be detected)
     *
     *                    req.onprogress = function (current, total) {
     *                        alert(current + " of " + total + " = " + ((total - current)/total) + "%");
     *                    }
     *
