Does there exist any syntactic sugar for the Javascript prototype field?

Question

Is there any way to clean up all the Obj.prototype.field = statements in my javascript code? I am using jQuery. I want to do the same thing except not have every other word in my code be prototype . Maybe what I'm asking is impossible -- if so, just let me know and that will be the answer.

I found this to be an ungoogleable question because there is a js library named "Prototype"...

Answer 1

Use jQuery.extend . The properties of the second argument will be copied over to the first one:

$.extend(Obj.prototype,{
   field1: "hi there",
   func1: function(){
     //do stuff
   }
});

This is what jQuery uses internally, jQuery.fn being an alias for jQuery.prototype:

jQuery.fn.extend({
   attr: function( name, value ) {
      return jQuery.access( this, jQuery.attr, name, value, arguments.length > 1 );
   },

   removeAttr: function( name ) {
       return this.each(function() {
                jQuery.removeAttr( this, name );
        });
   }, ...

Answer 2

You could also do something like

var p = Obj.prototype;

p.newMethod = function(window.alert("Hi! I live"));
p.newProperty = false;

Answer 3

maybe just:

Obj.prototype = {
  run: function(){},
  fooBar: function(test1,test2){}  
};

?

Answer 4

have a look at the "extend" functions of libraries like jQuery and YUI3

http://api.jquery.com/jQuery.extend/

http://yuilibrary.com/yui/docs/yui/yui-extend.html http://yuilibrary.com/yui/docs/yui/yui-extend.html

Also look at merge (jQuery, YUI3) and augment (YUI3) and at the usage.
