  1. Building Solutions For Internet Explorer 5.0 Dave MassyProgram ManagerInternet ExplorerMicrosoft Corporation

  2. Agenda • Introduction • Internet Explorer - The Rich Client • Dynamic HTML • Components - Behaviors • Summary

  3. Introduction • XML - Defines the Structure of Data • XSL - Data Transformation • Transformation on Server or Client • Dynamic HTML - User Interface • Client Side only • Use Script to provide User Interaction

  4. XML Transfer Model Network Client Server XSL/ HTML Browser DB ASP XML Parser XMLdoc XML Parser

  5. Internet Explorer As The Rich Client • Deploy Applications on the server • No installation on Client Machine • Lower Administration Costs • Reduce Server hit • Greater Scalability • Integration with Office 2000

  6. Dynamic HTML • Internet Explorer 4.0 • Introduced Dynamic HTML • Internet Explorer 5.0 • Enhanced DHTML support • Performance • Robustness • Completeness • Components

  7. What Is Dynamic HTML? • Every HTML Element is Programmable • Change Content without reloading the page • innerHTML to access content of Element, e.g., <span id="s1">This is content of Span s1</span> <input type=text id=t1> <button onclick="s1.innerHTML=t1.value">Click me</button>

  8. Cascading Style Sheets (CSS) • Styles to format content • Every Style is Programmable • Change Formatting without reloading the page, e.g., <span id="s1" style="color:red">This is content of Span s1</span> <button onclick="change();">Click me</button> <script> function change(){ if (s1.style.color=='red') { s1.style.color='blue'; } else { s1.style.color='red'; } } </script>

  9. Enable Enterprise-Ready Applications • Application-fast, not just browser-fast • Faster • Large documents and data binding • Smarter • Fixed table layout <TABLE STYLE="table-layout:fixed” WIDTH=600> <COL WIDTH=100><COL WIDTH=300><COL WIDTH=200> <TR> …

  10. Page Rendering Performance IE Load Time 4.01 IE 5 0 100 200 300 400 Tasks

  11. Enable Enterprise-Ready Applications • Drag-and-drop • Full application-level drag-and-drop support • Between frames • To/from other applications • Context Menu Support • Print from Script • Dialog Extensions • Modeless • Resizeable

  12. Enable Enterprise-Ready Applications • Persistence • No 4k limit like cookies • XML format • Persist your own data: • In a single session (saveHistory) • Across sessions (saveFavorite) • Between pages on your site (userData)

  13. Persistence Example <HTML> <HEAD> <META NAME="save" content="snapshot"> <STYLE TYPE="text/css"> .saveHistory { behavior:url(#default#saveHistory);} </STYLE> </HEAD> <BODY> <H2>Save the text in a Textarea</H2> <TEXTAREA ID=Y CLASS=saveHistory VALUE="default text"> </TEXTAREA> <H2>Save the style attributes of a DIV</H2> <DIV CLASS=saveHistory ID=Z STYLE="background-color: red">default div text<BR></DIV> ...

  14. New Object Model Support • New support for W3C DOM Level 1 • Less knowledge of HTML required • Significantly faster • Allows operations on document tree • Create Elements • Create Text • Insert/Remove/Delete elements • Examples • Table Editor, Create Elements, Sorter

  15. Example - Table Editing With The DOM function addCell() { var r, p, c, nc, text; if (lastSelection == null) return false; r = lastSelection; if (r.tagName == "TD") { r = r.parentElement; c = lastSelection; } else c = null; nc = document.createElement("TD"); text = document.createTextNode("New Cell"); nc.insertBefore(text, null); r.insertBefore(nc, c); select(nc); return nc; }

  16. Vector Markup Language • Can put vector graphic shapes directly on the HTML Page • Work just like any HTML Elements • Examples • VML Editor, Stock Graphs

  17. Make DHTML More Accessible Designer/Author CSS and HTML Engineer Scripting Business Manager

  18. DHTML Behaviors • Make the power of DHTML more accessible to authors • Easy separation between content and behavior • Removes engineering bottleneck • Leverages engineering efforts across many pages • DHTML Behaviors • Extend the power of existing HTML tags • Extend the power of HTML by creating custom tags

  19. DHTML BehaviorsExtend existing HTML tags • Use CSS behavior attribute to apply behavior to any tag • <style> • .mask {behavior: url(mask.htc);} • .blue {background-color: blue;} • </style> • <input type=text class=mask maskType=date> • <input type=text class=blue> • Secure - it’s just script + HTML • Behaviors can expose new object model • New methods, properties, and events • Implement behaviors in either script or compiled code (COM object)

  20. DHTML BehaviorsDefine custom tags • New in Internet Explorer 5.0: Use CSS with custom tags • Declare XML namespace <HTML xmlns:myns /> • Use CSS and behavior to define default style for custom tags <STYLE> @media all { MYNS\:FLY{color:red;behavior:url(fly.htc);} } </STYLE> • Use custom tags with HTML <MYNS:FLY>This <B>content</B> will fly</MYNS:FLY>

  21. Custom Tags In HTML • Custom tag Namespaces avoid name conflicts • <MYNS:TITLE>This is not an HTML title </MYNS:TITLE> • Namespace is defined by the page author • Downlevel Browsers ignore tags and render the content • Use custom tags to define structure • Example enclose all Product prices in <PROD:PRICE> tag

  22. Building Behaviors: Easy! • Script • Author using JavaScript or VBScript • Similar to script in the document • Provides full access to the DOM • Simple COM component • Author on top of simple, well defined interfaces • Create true extensions to the browser • Provides access to the DOM

  23. Building Behaviors In Script • (collapsing bullet point) <UL class=list> • <script language="jscript"> • attachEvent("onclick", event_onclick); • function event_onclick(){ • for (i = 0; i < children.length; • i++){ • mystyle = children[i].style; • if (mystyle.display == "none"){ • mystyle.display = ""; • } else { mystyle.display = • "none"; • } } } • </script>

  24. Behaviors - Object Model • Properties • <PUBLIC:PROPERTY name=delay /> • Refer to delay property name in script • Methods • <PUBLIC:METHOD name=start /> • Script function named start • Events • <PUBLIC:EVENT name=onFinishedFly id=finfly /> • Call finfly.fire() inscript to fire event

  25. Resources • Websites • http://www.microsoft.com/windows/ie/ie5- Highlights major features • http://msdn.microsoft.com/workshop- Reference, Samples, Overviews • Books • “Dynamic HTML Reference and Software Development Kit” - Microsoft • “Programming Internet Explorer 5.0”by Scott Roberts • “DHTML for Dummies” by Michael Hyman

  26. In Closing • Internet Explorer 5.0 • Fast and Stable • Enabling Enterprise-Ready Applications • Bring the Power of DHTML to Everyone • Drag/Drop • Dynamic Properties • Persistence • Context Menus • DHTML Behaviors • Etc.
