Question

1. I’d like to have an anchor in the page that performs the same function as the tab.
   I was only able to get it to work if I placed something like $('#tabs ul a:first').click() in the onclick event of the particular anchor. Note: the href has no effect on the links external to the tab plugin; it is probably only used in the anchors in the tab when constructing their click event.

2. I came across a jQuery binding problem.
   Instead of performing a DOM lookup for each link, it’d be better to store that in a variable and add the click event to the external anchor’s click event. However, when a selector returns multiple objects, the object in the array (it’s most likely not an array that’s returned, but an object) does not seem to have any functions.

$(function() {
    $( "#tabs" ).tabs(); 
    
    var tabs = $('#tabs ul li a');
    
    $( "#links2 a" ).each(function(index){
       $(this).bind('click',function(){
          (tabs[index]).click();
       });
    });
});

   <a href="#" onclick="$('#tabs li a:eq(1)').click()//not sure if this is the best way to reference">bar</a>       
   <a href="#" onclick="$('#tabs li:last a').click()">baz</a>

Answer 1

Instead of

(tabs[index]).click();

it should be

tabs.eq(index).click();

The first form gets you the raw DOM element, while the second gets you a jQuery-wrapped DOM element. There’s no “click” method on <a> element nodes, at least no standard method. (Alternatively, $(tabs[index]) would work too.)
