Select currently viewed slide for callback function in SlideJS plugin

Question

I asked this question on the plugin's forums, but I think they are dead, no point. Maybe you can help me.

All I need to do is select the currently viewed slide element, so I can pop a caption over it with .slideToggle(). What I tried was

callback: {
             complete: function(number){
               $("#slides").find("slidesjs-index=\""+number+"\"").children(".cap").slideToggle();
            }
          }

But that returns a syntax error:

Uncaught Error: Syntax error, unrecognized expression: slidesjs-index="2"

Which I presume is because slidesjs-index="(index of the automatically enumerated element)" is not a valid HTML attribute, so the browser does not accept that script. Can you please suggest some method of selecting the current slide so I can call the callback function to pop the caption over the relevant image?

Is there maybe a way to just search inside the tag name for a matching string and select the element using that?

Answer 1

It was a problem with syntax:

slidesjs-index=\""+number+"\""

Is supposed to be

slidesjs\-index\=\""+number+"\""

Such that it's a string, not an expression. Adding escape characters fixed the problem.
