Calling the remote server means using an asynchronous callback that makes a request and waits for a response. The HTML code remains almost identical, with a change in the ConvertToBolded function: <html> <head><title>Processing Local Data</title></head> <script language="JavaScript" src="/ajax/lib/factory.js"></script> <script language="JavaScript" src="/ajax/lib/asynchronous.js"></script> <script language="JavaScript" src="/ajax/lib/events.js"></script> <script language="JavaScript" type="text/javascript"> var nav = new DecoupledNavigation(); function OnClick( common) { common.state = new TextState( "divDestination", document.getElementById( "txtContent").value); return true; } function ConvertToBolded( common) { common.parent.initializeRemote( common); common.complete = function( cmdEmbedded, status, statusText, responseText, responseXML) { cmdEmbedded.state.text = responseText; return true; EBVN } var buffer = common.state.text; common.async.post( "/ajax/chap10/remotecontent", "application/text", buffer.length, buffer); return true; } </script> <body> <div> <table border="1"> <tr> <td><input type="text" id="txtContent"></td> </tr> <tr> <td> <input type="button" value="Transfer" onclick="return nav.call ( event, OnClick, ConvertToBolded, InjectHTML)"/> </td> </tr>

<tr> <td id="divDestination">Nothing yet</td> </tr> </table> </div> </body> </html> The changed content in the HTML page is bold. The changes are to only one function. This means that the change from processing data locally to remotely has been implemented transparently without updating the HTML elements responsible for the user interface, the OnClick or the InjectHTML function. The overall application still looks and feels the same, with the only noticeable change being the speed of converting the text to bold. Let s focus on ConvertToBolded, which is illustrated again as follows: function ConvertToBolded( common) { common.parent.initializeRemote( common); common.complete = function( cmdEmbedded, status, statusText, responseText, responseXML) { cmdEmbedded.state.text = responseText; return true; } var buffer = common.state.text; EBVN common.async.post( "/ajax/chap10/remotecontent.html", "application/text", buffer.length, buffer); return true; } In the implementation of the ConvertToBolded, there is a call to initializeRemote. The method initializeRemote sets up the functions and data members necessary to make a remote server call by using the Asynchronous type. The definition of the common.complete function is required by Asynchronous and is called when the remote call has completed. The existence of common.complete splits the Common Data functionality into two pieces. The first piece is the creation of the remote server call request, and the second piece is the processing of the results. The last part of the ConvertToBolded method is to send the data to the server by using the method common.async.post (HTTP POST). Sending the data is the first step of the two-step Common Data functionality. The server will process the data and return a modified state to the caller. The modified state is then processed by the common.complete method, which is the second step of the two-step Common Data functionality. As the second step is part of the Common Data functionality, the Presentation functionality can be called thereafter. Before the implementation of initializeRemote is started, a better way to explain the calling sequence is to illustrate it. Figure 6-16 makes it simpler to explain how the method initializeRemote is implemented.

In Figure 6-16, when the user clicks the Transfer button, the event onclick is triggered. The onclick event calls the method nav.call, which is of the type DecoupledNavigation. DecoupledNavigation has two methods (call and complete) that are of interest when calling a remote server. Executing the call method will call the Action functionality (OnClick) and the Data functionality (ConvertToBolded). The Data functionality will wire up the asynchronous HTTP call, and call the remote server. At this point the Decoupled Navigation pattern gives up control and waits for a response from the server. When the server receives a response, it is captured by DecoupledNavigation.complete, which then delegates to common.complete. Calling common restarts the Decoupled Navigation pattern and finishes the Data functionality part. Thereafter, the Presentation functionality starts, which calls the function InjectHTML. Calling InjectHTML causes the user interface to change and contains the bold code. Now that you understand the sequence of events, let s look at the method initializeRemote, which is responsible for wiring together the various methods: function DecoupledNavigation_InitializeRemote( common) { common.async = new Asynchronous(); common.complete = function( obj, status, statusText, responseText, responseXML) {} common.openCallback = function( xmlhttp) {} common.async.openCallback = function( xmlhttp) { common.openCallback( xmlhttp); };
