Method Detail
abort
native static void abort(JavaScriptObject xmlHttpRequest)(Code)



getAllResponseHeaders
native static String getAllResponseHeaders(JavaScriptObject xmlHttpRequest)(Code)



getBrowserSpecificFailure
native static String getBrowserSpecificFailure(JavaScriptObject xmlHttpRequest)(Code)
Tests if the JavaScript XmlHttpRequest.status property is readable. This can return failure in two different known scenarios:
  1. On Mozilla, after a network error, attempting to read the status code results in an exception being thrown. See https://bugzilla.mozilla.org/show_bug.cgi?id=238559.
  2. On Safari, if the HTTP response does not include any response text. See http://bugs.webkit.org/show_bug.cgi?id=3810.

Parameters:
  xmlHttpRequest - the JavaScript XmlHttpRequest objectto test a String message containing an error message if theXmlHttpRequest.status code is unreadable or null ifthe status code could be successfully read.



getHeaders
static Header[] getHeaders(JavaScriptObject xmlHttpRequest)(Code)
Returns an array of headers built by parsing the string of headers returned by the JavaScript XmlHttpRequest object.
Parameters:
  xmlHttpRequest - array of Header items



getReadyState
native static int getReadyState(JavaScriptObject xmlHttpRequest)(Code)



getResponseHeader
native static String getResponseHeader(JavaScriptObject xmlHttpRequest, String header)(Code)



getResponseText
native static String getResponseText(JavaScriptObject xmlHttpRequest)(Code)



getStatusCode
native static int getStatusCode(JavaScriptObject xmlHttpRequest)(Code)



getStatusText
native static String getStatusText(JavaScriptObject xmlHttpRequest)(Code)



isResponseReady
static boolean isResponseReady(JavaScriptObject xmlHttpRequest)(Code)



open
native static String open(JavaScriptObject xmlHttpRequest, String httpMethod, String url, boolean async)(Code)
Opens the request and catches any exceptions thrown. If an exception is caught, its string representation will be returned. This is the only signal that an error has occurred.
Parameters:
  xmlHttpRequest - JavaScript XmlHttpRequest object
Parameters:
  httpMethod - the method to use for open call
Parameters:
  url - the URL to use for the open call
Parameters:
  async - true if we should do an asynchronous open error message if an exception is thrown or null if there is none



open
native static String open(JavaScriptObject xmlHttpRequest, String httpMethod, String url, boolean async, String user)(Code)
Opens the request and catches any exceptions thrown. If an exception is caught, its string representation will be returned. This is the only signal that an error has occurred.
Parameters:
  xmlHttpRequest - JavaScript XmlHttpRequest object
Parameters:
  httpMethod - the method to use for open call
Parameters:
  url - the URL to use for the open call
Parameters:
  async - true if we should do an asynchronous open
Parameters:
  user - user to use in the URL error message if an exception is thrown or null if there is none



open
native static String open(JavaScriptObject xmlHttpRequest, String httpMethod, String url, boolean async, String user, String password)(Code)
Opens the request and catches any exceptions thrown. If an exception is caught, its string representation will be returned. This is the only signal that an error has occurred.
Parameters:
  xmlHttpRequest - JavaScript XmlHttpRequest object
Parameters:
  httpMethod - the method to use for open call
Parameters:
  url - the URL to use for the open call
Parameters:
  async - true if we should do an asynchronous open
Parameters:
  user - user to use in the URL
Parameters:
  password - password to use in the URL error message if an exception is thrown or null if there is none
