Question

$('.list-links-nested a').each(function(){      
  currentPage(this);
});

$("#menu-main > li > a").each(function(){
  currentPage(this);  
});

$("#menu-sub a").each(function(){      
  currentPage(this);        
});

Any suggestion on how to write it better instead of repeating the function called?

Updated code and it works:

var links = $(".list-links-nested a, #menu-main > li > a");
links.each(currentPage);

Answer 1

You can use a comma in your string to provide multiple selectors.

$(".list-links-nested a, #menu-main > li > a, #menu-sub a").each(currentPage);

You can also pass currentPage as an argument itself and use this directly, instead of the argument you were passing.
