docs.jquery.com/downloading_jquery and http://jpoint.codeplex.com/

• Faster than the DOM• Cross Browser Supported

10www.mindSHIFT.com We make IT work for your business.®

Evolution

13www.mindSHIFT.com We make IT work for your business.®

with Ajax…

14www.mindSHIFT.com We make IT work for your business.®

• Selectors

$(“#someId”)$(“:text”)$(“.someclass”)$(“#sometabletr:even”)

• Events

click, focusshow, hide OR slideDown, slideUp, fadeIn, fadeOutExample: $(“.someClass”).show(“slow”, someFunction)

JQuery Syntax

15www.mindSHIFT.com We make IT work for your business.®

<a href="#" onclick="toggle_visibility('foo');">Click here to toggle visibility of #foo</a>

function toggle_visibility(id) { var e = document.getElementById(id); if(e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; }

Example – Show/Hide the old way

16www.mindSHIFT.com We make IT work for your business.®

$().ready(function(){$("a").click(function(){$("#more").toggle("slow");

return false; }); });

Example – Show/Hide with JPoint

17www.mindSHIFT.com We make IT work for your business.®

function GetXmlHttpObject(handler) { var objXmlHttp = null; //Holds the local xmlHTTP object instance

//Depending on the browser, try to create the xmlHttp object if (is_ie){ var strObjName = (is_ie5) ? 'Microsoft.XMLHTTP' : 'Msxml2.XMLHTTP'; try{ objXmlHttp = new ActiveXObject(strObjName); objXmlHttp.onreadystatechange = handler; } catch(e){ //Object creation errored alert('Verify that activescripting and activeX controls are enabled'); return; } } else{ // Mozilla | Netscape | Safari objXmlHttp = new XMLHttpRequest(); objXmlHttp.onload = handler; objXmlHttp.onerror = handler; } //Return the instantiated object return objXmlHttp;

}

Example – Ajax the old way

18www.mindSHIFT.com We make IT work for your business.®

$.get("update_actions.aspx", {st: "yes", f: $(this).attr("ID")} );

Example – Ajax with JPoint

• Increases dynamic content display • Add interface enhancements without access to the Server• Lightweight – 14kb (Minified and Gzipped)• Cross-browser support (IE 6.0+, FF 1.5+, Safari 2.0+,

Opera 9.0+)• CSS-like syntax – easy for developers/non-developers to

understand• Active developer community • Extensible - plugins
