Question

Sorry for now using the most suitable technical words, but at the moment I’m experimenting with jQuery, and I seem to be repeating a certain function quite a lot, is there anyway to reference this function? Maybe by setting it as a variable or similar? Thanks

Answer 1

Yes, in javascript functions are first class citizens – the following is perfectly legal:

var localVariable = someNamespace.someFunction;
localFunction(); // Call function here

Update

Based on your code snippet, you’d want your function to be declared like so:

var showAll = function () {
  var images = $('.gallery li img');
  images.removeClass('hideme');
  images.addClass('showme');
  // nb could be done on one line like so:
  // $('.gallery li img').removeClass('hideme').addClass('showme');
};

Which would then be useable like so:

showAll();
