While I am a veteran OOP programmer, I am stumped on aspects of the scope of javascript objects.
What follows is a self-contained custom javascript class who's function is to manage a suite of containers as accordion sliders. I got it to work but must-be I'm not sure why it works because I cannot now use it with a 2nd suite of containers - ie reuse the class as an object managing additional suites of accordion containers.
Probably the easiest way to understand is to re-create the sample and script files and then load the sample into a browser.
You will find:

  • -the Left column working just fine.

The challenge:

  • -fix my cluggie script to then work with a second object which manages the Right column as elegantly.
  • -explain what I've done wrong.

Background:
The object, upon instantiation, receives a tag name eg h3 and an attribute to look for eg SliderL - it then init()'s upon document.load event and attaches a sliddown event to each of the h3/SliderL elements it finds on the page, thereby collecting the h3/SliderL's into said accordion suite, the sliderEngine then keeps track of which element might be opened and then closes it upon a subsequent slidedown event on another member of the suite - you'll see this working in the demo.
What I want is to enable the 2nd suite of accordion sliders on the right which are managed independently of the left.
!Most appreciative to any/everyone who can enlighten me

Asknight,

The contructor function Slider contains a strange mixture of ideas!

Chiefly, sliderEngine is global and is an instance of Slider , but Slider refers to sliderEngine internally where (I guess) it should use this . $ and dc are set within Slider but without a leading var , hence they are global. If a second instance of Slider is created, then these functions are redefined - no real problem and no error will be generated - just not necessary. As general utility functions, $ and dc can be declared and set outside Slider (eg. in the global namespace, though Javascript can be coded to expose ONLY ONE symbol to the global namespace and (according to some) should really be coded so to do).

In JavaScript constructor arguments remain active for the life of each instance and most of the code in Slider is written accordingly. Hence this.sliderTagType = .... and this.sliderAttribute = are not necessary and in fact these properties are never accessed. The default values should be applied to sliderTagType and sliderAttribute , not "this." derivitives.

Similarly, the property this.sliderEngine is defined but never accessed, which may be an attempt by somone to fix the code but it certainly doesn't work. The line this.sliderEngine = this; may be safely deleted.

I could go on .....

Main things to remember:

  • Inside functions (including functions used as contructors), variables are global unless localised with var .
  • this , in a contructor, stands for the constructed instance. It is not used to scope variables but rather to designate publicly accessible properties.

Something else you might like to investigate for yourself is a feature of JavaScript called "closure", which causes variables declared within constructors (and their arguments) to remain alive after the function has returned. Such variables are private though the word "private" like "public" and "class" and "extends" do not appear in the language definition as you may well be used to with other OO offerings.

In short the constructor is pretty well messed up, either by its original author or by people who have tried to improve it.

Sorry to pour cold water on it but the code you have found would take quite a lot of fixing.

I strongly suggest that you find a better example of a Javascript accordian. I think Jquery (or Prototype or both) has one built in. These JavaScript libs encourage (maybe even enforce) good coding practise, though they are a bit tricky to get started on.

Thanks for the input.
I agree the code needed help.
This morning I finally arrived at the tripp that was cloaking the solution.
In this case I needed not only the setInterval() to be able to reference the exact Slider instance but also, and of course the event function attached to the xhtml tags.
Heretofore, the event was only receiving a copy of the function within to call.
see the new code in how this was accomplished.
Additionally, the function which set's off the setInterval in a closure, now uses sliderEngine=this; in an appropriate way.
