기본 사용

XMLHttpRequest의 사용법은 아주 간단합니다. 이 개체의 인스턴스를 만들고, URL을 열고, 요청을 보내면 됩니다. 그 후에는 인스턴스의 결과 문서와 HTTP 상태 코드를 사용할 수 있게됩니다.

var req = new XMLHttpRequest();

req.open('GET', 'http://www.mozilla.org/', false);

req.send(null);

if(req.status == 200)

  dump(req.responseText);

[NoInterfaceObject]

interface XMLHttpRequestEventTarget : EventTarget {

  // for future use

};



[Constructor]

interface XMLHttpRequest : XMLHttpRequestEventTarget {

  // event handler attributes

           attribute Function onreadystatechange;



  // states

  const unsigned short UNSENT = 0;

  const unsigned short OPENED = 1;

  const unsigned short HEADERS_RECEIVED = 2;

  const unsigned short LOADING = 3;

  const unsigned short DONE = 4;

  readonly attribute unsigned short readyState;



  // request

  void open(DOMString method, DOMString url);

  void open(DOMString method, DOMString url, boolean async);

  void open(DOMString method, DOMString url, boolean async, DOMString? user);

  void open(DOMString method, DOMString url, boolean async, DOMString? user, DOMString? password);

  void setRequestHeader(DOMString header, DOMString value);

  void send();

  void send(Document data);

  void send([AllowAny] DOMString? data);

  void abort();



  // response

  readonly attribute unsigned short status;

  readonly attribute DOMString statusText;

  DOMString getResponseHeader(DOMString header);

  DOMString getAllResponseHeaders();

  readonly attribute DOMString responseText;

  readonly attribute Document responseXML;

};
