Code Completion -- Aptana Eclipse Plugin

Question

I have been doing javascript development for the last couple weeks and have tried JSDT and Aptana to assist in code completion. JSDT wasn't very good at all, but I did have more luck with Aptana (used as eclipse plug-in, not the standalone product). The problem I'm encountering is that when I create javascript classes I cannot get code completion to work. For example, if I use the following then code completion doesn't work:

var foo = new function(value){
   this.myMethod= function(){
   }
}

I have also verified that the following won't work:

function foo(value){
   this.myMethod= function(){
   }
}

I have found that using a JSON style does work:

var foo = {
    myMethod: function(){

    }
}

Does anyone know why Aptana works for the last style, but not the first? Using the JSON style won't work for me because I have to have seperate instances of the class in question.

Also, I am not very successful in getting code completion to work across files. For example, if I have 3 files in the javascript directory then I usually cannot get Aptana to pick up the JSON style markup in the other two classes. This DID work at one point (for the first 2 classes I created), but since then whenever I add new classes they aren't picked up.

Thank you very much for you assistance.

Answer 1

I have identified that the following works:

/**
* The foo function
*/
function foo() { 
}

/**
* The bar function
* @param {Object} a Object a
 * @param {Object} b Object b
 */
function bar(a, b){
};

foo.prototype.b = bar;

var x = new foo();
x.b

In the above example the key is that you are registering the method using prototype. I also tried the following, but it didn't work.

/**
* The foo function
*/
var foo = new function() { 
}

/**
* The bar function
* @param {Object} a Object a
 * @param {Object} b Object b
 */
function bar(a, b){
};

foo.prototype.b = bar;

var x = new foo();
x.b

Any ideas what the difference is? Is the second a valid class in javascript?
