Onreadystatechange

The onreadystatechange event When a request to a server is sent, we want to perform some actions based on the response. The onreadystatechange event is triggered every time the readyState changes. The readyState property holds the status of the XMLHttpRequest x.open(GET, request, true); x.onreadystatechange = function() { //Your code here to handle readyState==4 and readyState==3 if (x.readyState==4 && x.status==200) { document.getElementById(resultsContainer).innerHTML=Raw JSON Data: <br>+x.responseText+<br><br>; } else if (x.readyState==2) { document.getElementById(resultsContainer).innerHTML=Processing Request; } } x.send() onreadystatechange: Defines a function to be called when the readyState property changes: readyState: Holds the status of the XMLHttpRequest. 0: request not initialized 1: server connection established 2: request received 3: processing request 4: request finished and response is ready : responseText: Returns the response data as a string: responseXM myAjax. onreadystatechange = StatusAenderung; Daten empfangen [ Bearbeiten ] Die bei der Statusänderung aufgerufene Funktion soll nun prüfen, ob die Daten vollständig geladen wurden ( myAjax.readyState==4 ) und dass bei der Übertragung via HTTP keine Fehler auftraten ( myAjax.status==200 )

A propriedade XMLHttpRequest.onreadystatechange contém o manipulador de eventos que é chamado quando o evento readystatechange é disparado, ou seja, toda vez que a propriedade readyState do XMLHttpRequest é modificada. Atenção: Isso não deve ser usado com solicitações síncronas e não deve ser usado como código nativo onreadystatechange wird bei jeder Änderung des XHR-Zustands aufgerufen readyState zeigt grob den Fortschritt während des Requests an. XMLHttpRequest erzeugt, aber open() noch nicht aufgerufen, liefert 0. Signal beim erfolgreichen Eröffnen des XHR ist 1 (OPENED). Signal nach dem Senden und Empfang des Response Headers ist 2 (HEADERS_RECEIVED) var xmlHttp = null; try {xmlHttp = new XMLHttpRequest ();} catch (e) {// Fehlerbehandlung, wenn die Schnittstelle vom Browser nicht unterstützt wird.} if (xmlHttp) {xmlHttp. open ('GET', 'beispiel.xml', true); xmlHttp. onreadystatechange = function {if (xmlHttp. readyState == 4) {alert (xmlHttp. responseText);}}; xmlHttp. send (null); Der EventListener muss vor der Methode .send() stehen. Statt addEventListener() kann man die Funktion auch direkt an .onreadystatechange= zuweisen. Diese wird für diverse Zwischenstufen (1-4, beim alten Opera 12 nicht alle) aufgerufen. Es ist zu beachten, dass das Beispiel bei weitem nicht vollständig ist. In einer echten Anwendung, müssten wir zumindest noch dem Anwender ein Feedback darüber erteilen, wie unsere serverseitige Prüfung von statten gegangen ist. Außerdem ist es.

Event Property. object.onreadystatechange= handler; attachEvent Method. object.attachEvent(onreadystatechange, handler) addEventListener Method The onreadystatechange callback function was intended to be easy to use when working with scripting clients such as VBScript and JScript. Because the onreadystatechange property was not implemented through COM-based automation events, Visual Basic (and C/C++) applications need to implement this callback functionality differently

In Internet Explorer, the onreadystatechange event can also occur on elements. The applet, embed, frame, frameset, iframe, img, input:image, link, script, xml elements support the onreadystatechange event because they load data The onreadystatechange event listener. If the open method of the XMLHttpRequest object was invoked with the third parameter set to true for an asynchronous request, the onreadystatechange event listener will be automatically invoked for each of the following actions that change the readyState property of the XMLHttpRequest object. State changes work like this: State Description; 0 The request.

Passed one argument, the #Response Object. Response Object. All of the callback functions defined in the details object, if called, will receive this type of object as their first. Properties Description; onreadystatechange: Fires whenever the readyState property changes, allowing you to react to different stages of an asynchronous Ajax request. In some browsers such as Firefox, onreadystatechange fires multiple times while readyState is 3, letting you react as the data is downloading, such as to create a progress bar Fake XMLHttpRequest. Provides a fake implementation of XMLHttpRequest and provides several interfaces for manipulating objects created by it.. Also fakes native XMLHttpRequest and ActiveXObject (when available, and only for XMLHTTP progids). Helps with testing requests made with XHR.. The fake server and XHR can be used completely stand-alone by downloading sinon-server.js
