Jquery call function dynamically

Question

I have a following scenario that I have to call a function on a jquery object dynamically. The code looks like this :

$('div[class]').each(function(){
    var class=$(this).attr('class');

    // I want to now check if that function with the name of class exists for jquery
    // object. I need help here.
    // if that function exists, i need to apply that function to the enumerated object.
});

I want to now check if that function with the name of class exists for jQuery object. I need help here. If that function exists, I need to apply that function to the enumerated object.

I can't clearly see your use case here. What are you trying to accomplish? Explain it as in if I do this, then this should happen! If this element has the class abc I want the function abc to be executed, etc... — Shef

Yes, if the element has class abc then I want abc to be executed on that element if that function exists. — emphaticsunshine

Exists where, in the global namespace, in jQuery's jQuery.fn.function_here? Also, are you sure your elements will have only one class? — Shef

Multiple classes is a different case. I will parse it if I have that scenario. I want to check if it exists in globalspace. I have function like this: $.fn.funtion_name() — emphaticsunshine

I'm writing this of the top of my head so it might not work, but try:

if(jQuery.isFunction(jQuery[class]))
     jQuery[class](this);

Edit: if the function is a jquery method then try with:

 if(jQuery.isFunction(jQuery.fn[class])) {
     jQuery.fn[class](this);
     jQuery(this)[class]();    // alternative call syntax
 }
