1//** Tab Content script v2.0- © Dynamic Drive DHTML code library (http://www.dynamicdrive.com) 2//** Updated Oct 7th, 07 to version 2.0. Contains numerous improvements: 3// -Added Auto Mode: Script auto rotates the tabs based on an interval, until a tab is explicitly selected 4// -Ability to expand/contract arbitrary DIVs on the page as the tabbed content is expanded/ contracted 5// -Ability to dynamically select a tab either based on its position within its peers, or its ID attribute (give the target tab one 1st) 6// -Ability to set where the CSS classname "selected" get assigned- either to the target tab's link ("A"), or its parent container 7//** Updated Feb 18th, 08 to version 2.1: Adds a "tabinstance.cycleit(dir)" method to cycle forward or backward between tabs dynamically 8//** Updated April 8th, 08 to version 2.2: Adds support for expanding a tab using a URL parameter (ie: http://mysite.com/tabcontent.htm?tabinterfaceid=0) 9 10////NO NEED TO EDIT BELOW//////////////////////// 11 12function ddtabcontent(tabinterfaceid){ 13 this.tabinterfaceid=tabinterfaceid //ID of Tab Menu main container 14 this.tabs=document.getElementById(tabinterfaceid).getElementsByTagName("li") //Get all tab links within container 15 this.enabletabpersistence=true 16 this.hottabspositions=[] //Array to store position of tabs that have a "rel" attr defined, relative to all tab links, within container 17 this.currentTabIndex=0 //Index of currently selected hot tab (tab with sub content) within hottabspositions[] array 18 this.subcontentids=[] //Array to store ids of the sub contents ("rel" attr values) 19 this.revcontentids=[] //Array to store ids of arbitrary contents to expand/contact as well ("rev" attr values) 20 this.selectedClassTarget="link" //keyword to indicate which target element to assign "selected" CSS class ("linkparent" or "link") 21} 22 23ddtabcontent.getCookie=function(Name){ 24 var re=new RegExp(Name+"=[^;]+", "i"); //construct RE to search for target name/value pair 25 if (document.cookie.match(re)) //if cookie found 26 return document.cookie.match(re)[0].split("=")[1] //return its value 27 return "" 28} 29 30ddtabcontent.setCookie=function(name, value){ 31 document.cookie = name+"="+value+";path=/" //cookie value is domain wide (path=/) 32} 33 34ddtabcontent.prototype={ 35 36 expandit:function(tabid_or_position){ //PUBLIC function to select a tab either by its ID or position(int) within its peers 37 this.cancelautorun() //stop auto cycling of tabs (if running) 38 var tabref="" 39 try{
