I'm using ajax and javascript to call external pages into content area.
i'm stuck at a point where, i want these tabs/menus to also perform scrollTo effect when clicked on them. I'm running in circles and no luck yet!
The js file is:
var ddajaxtabssettings={}
ddajaxtabssettings.bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
ddajaxtabssettings.loadstatustext="<img src='loading.gif' /> Requesting content..."
////main code BELOW////////////////////////
function ddajaxtabs(tabinterfaceid, contentdivid){
this.tabinterfaceid=tabinterfaceid //ID of Tab Menu main container
this.tabs=document.getElementById(tabinterfaceid).getElementsByTagName("a") //Get all tab links within container
this.enabletabpersistence=true
this.hottabspositions=[] //Array to store position of tabs that have a "rel" attr defined, relative to all tab links, within container
this.currentTabIndex=0 //Index of currently selected hot tab (tab with sub content) within hottabspositions[] array
this.contentdivid=contentdivid
this.defaultHTML=""
this.defaultIframe='<iframe src="about
:blank" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" class="tabcontentiframe" style="width:100%; height:auto; min-height: 100px"></iframe>'
this.defaultIframe=this.defaultIframe.replace(/<iframe/i, '<iframe name="'+"_ddajaxtabsiframe-"+contentdivid+'" ')
this.revcontentids=[] //Array to store ids of arbitrary contents to expand/contact as well ("rev" attr values)
this.selectedClassTarget="link" //keyword to indicate which target element to assign "selected" CSS class ("linkparent" or "link")
}
ddajaxtabs.connect=function(pageurl, tabinstance){
