  1. Enhancing a Grid Portlet Using JavaScript Phil Chung Komla Etse John Nipp

  2. Assignment Overview • Explore another way to create the portlet. • 6a uses separate .java file for portlet’s logic. • Use JavaScript to embed the Portlet’s logic directly in the code for the Portlet’s java server page (.jsp).

  3. Quick Overview of Java • Created by Netscape in 1995 • Purpose was to make web pages more interesting • An interpreted language • Scripts are not compiled prior to runtime • Statements processed at execution time • An object-based scripting language

  4. Implementing JavaScript in the Porlet Design • Still use the MainPage.jsp file • Include JavaScript within the HTML to create dynamic effects • Overcomes static nature of HTML.

  5. Installing JavaScript Libraries • Dojo Toolkit • Open source Dynamic-HTML (DHTML) toolkit written in JavaScript. • www.dojotoolkit.org

  6. Simple JavaScript Script Example of JavaScript instructions embedded within the HTML code <html> <head> <script type = “text/javascript”> Document.write(“This is file from inline HTML code.”) </script> </head> <body> </body> </html>

  7. <script type="text/javascript"> dojo.require("dojo.widget.TitlePane"); dojo.hostenv.writeIncludes(); dojo.require("dojo.widget.TabContainer"); dojo.require("dojo.widget.LinkPane"); dojo.require("dojo.widget.ContentPane"); dojo.require("dojo.widget.LayoutContainer"); dojo.require("dojo.widget.Checkbox"); dojo.require("dojo.widget.AccordionContainer"); dojo.require("dojo.widget.SplitContainer"); dojo.require("dojo.widget.*"); </script>

  8. <div class="main"> <div class="content" style="height:420px;"> <div dojoType="AccordionContainer" labelNodeClass="label" containerNodeClass="accBody" style="border: 1px solid #F9966B;HEIGHT:410px" id="mainaccordi"> <div id ="googlemap" dojoType="ContentPane" label="Google Map"> <form action="#" onsubmit="showAddress(this.address.value); return false"> <div id="googlemap2" style="width:1150px;height:300px"></div> <p> <b>Location:</b> <input type="text" size="60" name="address" value="1500 Marlynn Dr, Charlotte, NC" /> <input type="submit" value="Go!" /> </p> </form> </div> <div dojoType="SplitContainer" label="Email" open="true">

  9. Inserting JavaScript Code for Creation of Google Maps Interface <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIA AAAs91yCKatVZLSfyAUX3XJoxTwM0brOpm-All5BF6PoaKBxRWWERS2dI3 8LDyFef5VuB_jxekyAh-yXg" type="text/javascript"> </script>
