    <p>am using tabswitch from <a href="http://www.hieu.co.uk/blog/index.php/tabswitch/" rel="nofollow">http://www.hieu.co.uk/blog/index.php/tabswitch/</a></p> <p>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</p> <p>here is my code:</p> <pre><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);

    1. COWelcome to StackOverflow! Please click the "edit" link and look at the formatting tips shown to the right of the editing area. They tell you how to format code, etc. There's also an orange **[?]** that will give you more information. (Update: Looks like Nick formatted it for you. But please do take a look for next time.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.
