Supports a number of - * methods of transfer. - * - * Gets and Posts can be performed and the resultant page read in as text, - * JSON, or from the HTML DOM. - * - * Using an iframe causes the throbber to spin, this is good for providing - * feedback to the user that an action has occurred. - * - * Requests do not affect the history stack, see goog.History if you require - * this behavior. - * - * The responseText and responseJson methods assume the response is plain, - * text. You can access the Iframe's DOM through responseXml if you need - * access to the raw HTML. - * - * Tested: - * + FF2.0 (Win Linux) - * + IE6, IE7 - * + Opera 9.1, - * + Chrome - * - Opera 8.5 fails because of no textContent and buggy innerText support - * - * NOTE: Safari doesn't fire the onload handler when loading plain text files - * - * This has been tested with Drip in IE to ensure memory usage is as constant - * as possible. When making making thousands of requests, memory usage stays - * constant for a while but then starts increasing (<500k for 2000 - * requests) -- this hasn't yet been tracked down yet, though it is cleared up - * after a refresh. - * - * - * BACKGROUND FILE UPLOAD: - * By posting an arbitrary form through an IframeIo object, it is possible to - * implement background file uploads. Here's how to do it: - * - * - Create a form: - * <pre> - * <form id="form" enctype="multipart/form-data" method="POST"> - * <input name="userfile" type="file" /> - * </form> - * </pre> - * - * - Have the user click the file input - * - Create an IframeIo instance - * <pre> - * var io = new goog.net.IframeIo; - * goog.events.listen(io, goog.net.EventType.COMPLETE, - * function() { alert('Sent'); }); - * io.sendFromForm(document.getElementById('form')); - * </pre> - * - * - * INCREMENTAL LOADING: - * Gmail sends down multiple script blocks which get executed as they are - * received by the client. This allows incremental rendering of the thread - * list and conversations. - * - * This requires collaboration with the server that is sending the requested - * page back. To set incremental loading up, you should: - * - * A) In the application code there should be an externed reference to - * <code>handleIncrementalData()</code>. e.g. - * goog.exportSymbol('GG_iframeFn', goog.net.IframeIo.handleIncrementalData); - * - * B) The response page should them call this method directly, an example - * response would look something like this: - * <pre> - * <html> - * <head> - * <meta content="text/html;charset=UTF-8" http-equiv="content-type"> - * </head> - * <body> - * <script> - * D = top.P ? function(d) { top.GG_iframeFn(window, d) } : function() {}; - * </script> - * - * <script>D([1, 2, 3, 4, 5]);</script> - * <script>D([6, 7, 8, 9, 10]);</script> - * <script>D([11, 12, 13, 14, 15]);</script> - * </body> - * </html> - * </pre> - * - * Your application should then listen, on the IframeIo instance, to the event - * goog.net.EventType.INCREMENTAL_DATA. The event object contains a - * 'data' member which is the content from the D() calls above. - * - * NOTE: There can be problems if you save a reference to the data object in IE. - * If you save an array, and the iframe is dispose, then the array looses its - * prototype and thus array methods like .join(). You can get around this by - * creating arrays using the parent window's Array constructor, or you can - * clone the array. - * - * - * EVENT MODEL: - * The various send methods work asynchronously. You can be notified about - * the current status of the request (completed, success or error) by - * listening for events on the IframeIo object itself. The following events - * will be sent: - * - goog.net.EventType.COMPLETE: when the request is completed - * (either sucessfully or unsuccessfully). You can find out about the result - * using the isSuccess() and getLastError - * methods. - * - goog.net.EventType.SUCCESS</code>: when the request was completed - * successfully - * - goog.net.EventType.ERROR: when the request failed - * - goog.net.EventType.ABORT: when the request has been aborted - * - * Example: - * <pre> - * var io = new goog.net.IframeIo(); - * goog.events.listen(io, goog.net.EventType.COMPLETE, - * function() { alert('request complete'); }); - * io.sendFromForm(...); - * </pre> - * - */ - -goog.provide('goog.net.IframeIo'); -goog.provide('goog.net.IframeIo.IncrementalDataEvent'); - -goog.require('goog.Timer'); -goog.require('goog.Uri'); -goog.require('goog.debug'); -goog.require('goog.debug.Logger'); -goog.require('goog.dom'); -goog.require('goog.events'); -goog.require('goog.events.EventTarget'); -goog.require('goog.events.EventType'); -goog.require('goog.json'); -goog.require('goog.net.ErrorCode'); -goog.require('goog.net.EventType'); -goog.require('goog.reflect'); -goog.require('goog.string'); -goog.require('goog.structs'); -goog.require('goog.userAgent'); - - - -/** - * Class for managing requests via iFrames. - * @constructor - * @extends {goog.events.EventTarget} - */ -goog.net.IframeIo = function() { - - /** - * Name for this IframeIo and frame - * @type {string} - * @private - */ - this.name_ = goog.net.IframeIo.getNextName_(); - - /** - * An array of iframes that have been finished with.
