Constructor

There is no direct constructor, since post and get create the instances.

Properties

complete

Boolean indicating whether the request has completed

Type

Example

// request.complete with an asynchronous call
var request = glow.net.get(
  "myFile.html", 
  {
    async: true,
    onload: function(response) {
      alert(request.complete); // returns true
    }
  }
);
alert(request.complete); // returns boolean depending on timing of asynchronous call

// request.complete with a synchronous call
var request = glow.net.get("myFile.html", {async: false;});
alert(request.complete); // returns true

nativeRequest

The request object from the browser.

Type

Description

This may not have the same properties and methods across user agents. Also, this will be undefined if the request originated from loadScript.

Example

var request = glow.net.get(
  "myFile.html", 
  {
    async: true,
    onload: function(response) {
      alert(request.NativeObject); // returns Object()
    }
  }
);

Methods

abort

Aborts an async request

Synopsis

myRequest.abort();

Returns

this

Description

The load & error events will not fire. If the request has been made using loadScript, the script may still be loaded but the callback will not be fired.

Example

var request = glow.net.get(
  "myFile.html", 
  {
    async: true,
    defer: true,
    onabort: function() {
      alert("Something bad happened.  The request was aborted.");
    }
  }
);
request.abort(); // returns "Something bad happened.  The request was aborted"

destroy

Release memory from a glow.net.loadScript call.

Synopsis

myRequest.destroy();

Returns

this

Description

This is called automatically by loadScript calls that have {callback} in the URL. However, if you are not using {callback}, you can use this method manually to release memory when the request has finished.

Example

var request = glow.net.loadScript('http://www.bbc.co.uk/whatever.js');

send

Sends the request.

Synopsis

myRequest.send();

Returns

This for async requests or a response object for sync requests

Description

This is done automatically unless the defer option is set

Example

var request = glow.net.get(
  "myFile.html", 
  {
    onload : function(response) {alert("Loaded");},
    defer: true
  }
);
request.send(); // returns "Loaded"

Events

Fired when the request is sucessful

Synopsis

glow.events.addListener(myRequest, "load", function(event) {
    // ...
});

Arguments
