{{APIRef("XMLHttpRequest")}}
- -

Use XMLHttpRequest (XHR) objects to interact with servers. You can retrieve data from a URL without having to do a full page refresh. This enables a Web page to update just part of a page without disrupting what the user is doing. XMLHttpRequest is used heavily in Ajax programming.

- -

{{InheritanceDiagram(650, 150)}}

- -

Despite its name, XMLHttpRequest can be used to retrieve any type of data, not just XML, and it supports protocols other than HTTP (including file and ftp).

- -

If your communication needs to involve receiving event data or message data from a server, consider using server-sent events through the {{domxref("EventSource")}} interface. For full-duplex communication, WebSockets may be a better choice.

- -

Constructor

- -
-
{{domxref("XMLHttpRequest.XMLHttpRequest", "XMLHttpRequest()")}}
-
The constructor initializes an XMLHttpRequest. It must be called before any other method calls.
-
- -

Properties

- -

This interface also inherits properties of {{domxref("XMLHttpRequestEventTarget")}} and of {{domxref("EventTarget")}}.

- -
-
{{domxref("XMLHttpRequest.onreadystatechange")}}
-
An {{domxref("EventHandler")}} that is called whenever the readyState attribute changes.
-
{{domxref("XMLHttpRequest.readyState")}} {{readonlyinline}}
-
Returns an unsigned short, the state of the request.
-
{{domxref("XMLHttpRequest.response")}} {{readonlyinline}}
-
Returns an {{domxref("ArrayBuffer")}}, {{domxref("Blob")}}, {{domxref("Document")}}, JavaScript object, or a {{domxref("DOMString")}}, depending on the value of {{domxref("XMLHttpRequest.responseType")}}. that contains the response entity body.
-
{{domxref("XMLHttpRequest.responseText")}} {{readonlyinline}}
-
Returns a {{domxref("DOMString")}} that contains the response to the request as text, or null if the request was unsuccessful or has not yet been sent.
-
{{domxref("XMLHttpRequest.responseType")}}
-
Is an enumerated value that defines the response type.
-
{{domxref("XMLHttpRequest.responseURL")}} {{readonlyinline}}
-
Returns the serialized URL of the response or the empty string if the URL is null.
-
{{domxref("XMLHttpRequest.responseXML")}} {{readonlyinline}}
-
Returns a {{domxref("Document")}} containing the response to the request, or null if the request was unsuccessful, has not yet been sent, or cannot be parsed as XML or HTML.
-
{{domxref("XMLHttpRequest.status")}} {{readonlyinline}}
-
Returns an unsigned short with the status of the response of the request.
-
{{domxref("XMLHttpRequest.statusText")}} {{readonlyinline}}
-
Returns a {{domxref("DOMString")}} containing the response string returned by the HTTP server. Unlike {{domxref("XMLHTTPRequest.status")}}, this includes the entire text of the response message ("200 OK", for example).
-
- -
-

Note: According to the HTTP/2 specification (8.1.2.4 Response Pseudo-Header Fields), HTTP/2 does not define a way to carry the version or reason phrase that is included in an HTTP/1.1 status line.

-
- -
-
{{domxref("XMLHttpRequest.timeout")}}
-
Is an unsigned long representing the number of milliseconds a request can take before automatically being terminated.
-
{{domxref("XMLHttpRequestEventTarget.ontimeout")}}
-
Is an {{domxref("EventHandler")}} that is called whenever the request times out. {{gecko_minversion_inline("12.0")}}
-
{{domxref("XMLHttpRequest.upload")}} {{readonlyinline}}
-
Is an {{domxref("XMLHttpRequestUpload")}}, representing the upload process.
-
{{domxref("XMLHttpRequest.withCredentials")}}
-
Is a {{domxref("Boolean")}} that indicates whether or not cross-site Access-Control requests should be made using credentials such as cookies or authorization headers.
-
- -

Non-standard properties

- -
-
{{domxref("XMLHttpRequest.channel")}}{{ReadOnlyInline}}
-
Is a {{Interface("nsIChannel")}}. The channel used by the object when performing the request.
-
{{domxref("XMLHttpRequest.mozAnon")}}{{ReadOnlyInline}}
-
Is a boolean. If true, the request will be sent without cookie and authentication headers.
-
{{domxref("XMLHttpRequest.mozSystem")}}{{ReadOnlyInline}}
-
Is a boolean. If true, the same origin policy will not be enforced on the request.
-
{{domxref("XMLHttpRequest.mozBackgroundRequest")}}
-
Is a boolean. It indicates whether or not the object represents a background service request.
-
{{domxref("XMLHttpRequest.mozResponseArrayBuffer")}}{{gecko_minversion_inline("2.0")}} {{obsolete_inline("6")}} {{ReadOnlyInline}}
-
Is an ArrayBuffer. The response to the request, as a JavaScript typed array.
-
{{domxref("XMLHttpRequest.multipart")}}{{obsolete_inline("22")}}
-
This Gecko-only feature, a boolean, was removed in Firefox/Gecko 22. Please use Server-Sent Events, Web Sockets, or responseText from progress events instead.

Event handlers

- -

onreadystatechange as a property of the XMLHttpRequest instance is supported in all browsers.

- -

Since then, a number of additional event handlers have been implemented in various browsers (onload, onerror, onprogress, etc.). See Using XMLHttpRequest.

- -

More recent browsers, including Firefox, also support listening to the XMLHttpRequest events via standard addEventListener() APIs in addition to setting on* properties to a handler function.

- -

Methods

- -
-
{{domxref("XMLHttpRequest.abort()")}}
-
Aborts the request if it has already been sent.
-
{{domxref("XMLHttpRequest.getAllResponseHeaders()")}}
-
Returns all the response headers, separated by CRLF, as a string, or null if no response has been received.
-
{{domxref("XMLHttpRequest.getResponseHeader()")}}
-
Returns the string containing the text of the specified header, or null if either the response has not yet been received or the header doesn't exist in the response.
-
{{domxref("XMLHttpRequest.open()")}}
-
Initializes a request. This method is to be used from JavaScript code; to initialize a request from native code, use openRequest() instead.
-
{{domxref("XMLHttpRequest.overrideMimeType()")}}
-
Overrides the MIME type returned by the server.
-
{{domxref("XMLHttpRequest.send()")}}
-
Sends the request. If the request is asynchronous (which is the default), this method returns as soon as the request is sent.
-
{{domxref("XMLHttpRequest.setRequestHeader()")}}
-
Sets the value of an HTTP request header. You must call setRequestHeader()after open(), but before send().
-
- -

Non-standard methods

- -
-
{{domxref("XMLHttpRequest.init()")}}
-
Initializes the object for use from C++ code.
-
- -
Warning: This method must not be called from JavaScript.
- -
-
{{domxref("XMLHttpRequest.openRequest()")}}
-
Initializes a request. This method is to be used from native code; to initialize a request from JavaScript code, use open() instead. See the documentation for open().
-
{{domxref("XMLHttpRequest.sendAsBinary()")}}{{deprecated_inline()}}
-
A variant of the send() method that sends binary data.
