The document discusses the potential of Adobe Integrated Runtime (AIR) for JavaScript developers. It provides examples of how AIR allows developing rich desktop applications with HTML, JavaScript and Flash. It demonstrates communicating with web services, working offline, drag and drop file handling, and saving data to files. AIR provides capabilities beyond the web like accessing local files and notifications while reusing existing Ajax skills.

- 16. Why AIR Appeals to Ajax Developers Same skill set Great offline capabilities File-system and Desktop integration Code re-use Strengths of HTML Cost of development Rapid prototyping Ease of distribution
- 18. Ajax is better in AIR Files (The Files are in the computer) Windows & Chrome Drag and Drop Copy and Paste (better) Offline Background process Notifications Keyboard Shortcuts
- 19. Usability Gotchas Keyboard shortcuts (tab, enter…) Throbbers / Activity indicators – no spinning IE Allow text to be copied Add functions for minimize, move, resize, close when chromeless Mouse hints (invitations)
- 20. AIR Versus Web Desktop What the heck is a Web Desktop? How is AIR the opposite of a Web Desktop?
- 22. What Makes up a HTML AIR App? A JS-based AIR app always includes: An HTML file An XML App Descriptor May also include: External JavaScript and CSS files Documents and images Flash files

- 28. Solution: Salesforce Customer Manager SalesForce API (Salesforce.com AJAX Connector 8.0) AIR Ajax Client for SalesForce API Online/Offline (servicemonitor.swf) Drag and Drop File Parsing (Vcard) Saving XML Files to disk
- 29. Yup. Some simple examples. In JavaScript? Really?
- 30. Problem 1 - Socket Communication How do we communicate with a foreign web service? Model for socket communication is flexible Cross domain OK Tools for handling sparse connections Upload files Use non-supported protocols
- 31. Monitoring Remote WS URLLoader simplifies XHR madness Start with an existing web service: http://www.nitobi.com/air/customerservice It returns XML:
- 32. Monitoring Remote WS Build a web form in an HTML page: Perform a URLRequest to retrieve the data based on the keyword. <form onsubmit="performSearch(); return false;"> <p>Customer Search: <input type="text" name="customerName" onkeyup="performSearch();" /> <input type=submit /></p> </form> <br /> <div id="resultsBlock"></div> function performSearch() { var url = "http://www.nitobi.com/air/customerservice?name=" + document.forms[0].customerName.value; var request = new air.URLRequest(url); var loader = new air.URLLoader(); loader.dataFormat=air.URLLoaderDataFormat.TEXT; loader.addEventListener(air.Event.COMPLETE,displayResults); loader.load(request); } air.ProgressEvent.PROGRESS, SECURITY_ERROR, OPEN, COMPLETE, HTTP_STATUS, IO_ERROR
- 33. Monitoring Remote WS Grab the result, convert to an XML document JSON is possible but requires extra steps Current security model inhibits use of eval(); function displayResults(event){ var loader2=event.target; var parser = new DOMParser(); var doc = parser.parseFromString(loader2.data,"text/xml"); var companyList = doc.getElementsByTagName("company"); var resultString = "" for (var i = 0; i < companyList.length; i++) { resultString += companyList[i].firstChild.nodeValue + ", "; } document.getElementById('resultsBlock').innerHTML = resultString; }
- 34. Going Offline Toolbox for working offline helps with business applications. Monitor network connectivity with servicemonitor.swf Use local SQL database to cache data Reconnect later Transmit
- 35. Going Offline with servicemonitor.swf Checks connectivity to website or socket connection Periodic polling
- 36. Going Offline with servicemonitor.swf Use of external SWF library Checking availability of particular URL: Checking availability of particular socket: var monitor; function checkURLStatus(url) { var req = new air.URLRequest(url); monitor = new window.runtime.air.net.URLMonitor(req); monitor.pollInterval = 5000; monitor.addEventListener(air.StatusEvent.STATUS, showStatus ); monitor.start(); } function checkSocketStatus(host,port) { monitor = new window.runtime.air.net.SocketMonitor( host , port ); monitor.pollInterval = 5000; monitor.addEventListener(air.StatusEvent.STATUS, showStatus); monitor.start(); } <script type="application/x-shockwave-flash" src="servicemonitor.swf" ></script>
- 37. Drag and Drop File type associations Drag-on behavior Bidirectional
- 38. Drag and Drop Add event listeners Accept onEnter Accept onDrop function setupEvents() { window.htmlControl.addEventListener( runtime.flash.events.NativeDragEvent.NATIVE_DRAG_ENTER, doEnter ); window.htmlControl.addEventListener( runtime.flash.events.NativeDragEvent.NATIVE_DRAG_DROP , doDrop ); } function doEnter( event ) { runtime.flash.desktop.DragManager.acceptDragDrop( window.htmlControl ); } function doDrop( event ) { var fileString = ''; var files = event.transferable.dataForFormat(air.TransferableFormats.FILE_LIST_FORMAT,air.TransferableTransferMode.CLONE_PREFERRED ); for( var f = 0; f < files.length; f++ ) { var fileStream = new runtime.flash.filesystem.FileStream(); fileStream.open(files[f], runtime.flash.filesystem.FileMode.READ); var fileBytes = new runtime.flash.utils.ByteArray(); fileStream.readBytes(fileBytes); var fileString = fileBytes.toString(); fileStream.close(); } displayGrid(fileString); }
- 39. Drag and Drop Draw the grid from the CSV data: function displayGrid(csvdata) { dataSet = csvdata.split(""); for (i = 0; i <dataSet.length; i++) { dataSet[i] = dataSet[i].split(","); } var resString = "<form name=amp;quot;csvFormamp;quot;><table>"; for (i = 0; i <dataSet.length; i++) { resString += "<tr>"; for (b = 0; b <dataSet[i].length; b++) { if (!isNumeric(dataSet[i][b]) || (dataSet[i][b].length < 1)) { resString += "<td style=amp;quot;background-color: #f0f0f0; font-weight:bold; color:#000099;amp;quot;>" + dataSet[i][b] + "</td>"; } else { resString += "<td><input type=text name=amp;quot;c" + b + "_" + i + "amp;quot; value=amp;quot;" + dataSet[i][b] + "amp;quot; size=amp;quot;6amp;quot;></td>"; } } resString += "</tr>"; } resString += "</table></form>"; document.getElementById('tableData').innerHTML = resString; }
- 40. File IO – Saving back to Excel Serialize your data to a string: function serializeToXLS() { var resString = "<table>"; for (i = 0; i <dataSet.length; i++) { resString += "<tr>"; for (b = 0; b <dataSet[i].length; b++) { if (!isNumeric(dataSet[i][b]) || (dataSet[i][b].length < 1)) { resString += "<td style=amp;quot;background-color: #f0f0f0; font-weight:bold; color:#000099;amp;quot;>" + dataSet[i][b] + "</td>"; } else { resString += "<td>" + document.forms["csvForm"]["c" + b + "_" + i].value + "</td>” } } resString += "</tr>"; } resString += "</table>"; return resString; } JavaScript String
- 41. File IO – Saving back to Excel Use FileStream to write to the disk Deposit file on Desktop or any other location OS Independent Charset aware. function saveData() { var file = air.File.desktopDirectory.resolvePath("out.xls"); var stream = new air.FileStream(); stream.open(file, air.FileMode.WRITE ); stream.writeMultiByte( serializeToXLS(), air.File.systemCharset ); stream.close(); }
