1.4 XMLHttpRequest Object Methods
The XMLHttpRequest object provides various methods to initiate and
process HTTP requests, which are discussed in detail in the following
sections.
1.4.1 The abort() Method
The abort()method is used to halt the HTTP request associated with an
XMLHttpRequest object to reset the object to the uninitialized state.
1.4.2 The open() Method
The open(DOMString method, DOMString uri, boolean
async, DOMString username, DOMString password)
method is called to initialize an XMLHttpRequest object. The method
parameter is required and specifies the HTTP method (GET, POST, PUT,
DELETE, or HEAD) that want to use to send the request. To send data to
the server, use the POST method. To retrieve data from the server, use the
GET method. The uri parameter specifies the server URI to which the
XMLHttpRequest object sends the request.
