hi am having a problem, am using tabswitch from http://www.hieu.co.uk/blog/index.php/tabswitch/
am trying to add extra functionality to return the total number of tabs am trying to return a value within the function the alert statement in getLength outputs the correct value but the value returned is undefined
here is my code:
//the function within tabswitch function:
var getLength = function(){
var $totalPages = parseInt((Obj.length));
alert('getLength function totalPages = '+$totalPages);
$('.pagetotal').html(' '+$totalPages); //this correctly sets the element to the correct value
return ($totalPages); // this returns undefined?
}
function setTabIndex(){
$totalPages = $('.SlideTab').tabSwitch('getlength'); //undefined?
$mypage = parseInt($(".SlideTab").tabSwitch('index')+1);
$currentIndex = parseInt($(".SlideTab").tabSwitch('index'));
$('.pageon').html('Page '+$mypage+' of');
alert('totalPages = '+$totalPages+' myPage = '+$mypage+' currentindex = '+$currentIndex); //returns undefined for total pages??
setButtons();
};
the full tabswitch code:
