Javascript: Accessing functions within Anonymous function

2 Views

Using jQuery as suggested by WordPress, I have wrapped my code in an anonymous function so that jQuery will not conflict with other javascript libraries: 

(function($) {

    // Inside of this function, $() will work as an alias for jQuery()
    // and other libraries also using $ will not be accessible under this shortcut

})(jQuery);

The problem is that I want to split my code into two files: 1) main.js and 2) utility.js.

How can the main program (main.js) call functions within the other file (utility.js) when both are encapsulated?

utility.js 

(function($) { 

function doSomething() {
    /* code here */
}

})(jQuery);

main.js 

(function($) { 

$(document).ready(function(){
    doSomething();
}

})(jQuery);

Thanks

  1. You can use to return an object out of this utility.js: 

    (function($, win) {
  win.util = function(){
    this.doSomething = function() {
      $('pre').append('util.js');
    }
  };
})(jQuery, window);

(function($, $U) { // <----referred it with $U

  $(document).ready(function() {
    $U.doSomething();
  });

})(jQuery, new util()); //<----pass the util object here.
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<pre></pre>

    Actually i like the way to use it in OOJS way. Try creating a constructor and pass a new object.

  2. The simplest solution is to assign all functions in utility.js to some global object. Assuming your code works in the browser you could do something like this:

    utility.js

    (function($, context) { 

context.Utility = {
    doSomething: function() {
        /* code here */
    }
};

})(jQuery, window);

    main.js

    (function($, Utility) { 

$(document).ready(function(){
    Utility.doSomething();
}

})(jQuery, Utility);

    A more general solution would be to use asynchronous module loading (http://requirejs.org/) or a tool like JSPM to manage modules in your application.
