construct object function with array parameter

Question

In Javascript, if I want to construct a object which can be used into polymorphism and inheritance, I would like to code like this:

function clicked(label,name,value){
    this.label=label;
    this.name=name;
    this.value=value;
}

When I want to create new object, I can use following methods:

var clicked1= new clicked("a","b","c");
var clicked2= new clicked("d","e","f");
clicked1.label="h";

But here I want to change some parameter into array. How can I do. for example, Change every label keys into label[ ], thus I can use later:

clicked1.label.push("xxx");

just.... some parameter are type of array instead of just string, I want to know how to change my code for that... — WillDo

So just use an array instead of a string. What did you try writing? What don't you understand? — SLaks

Types are very simple in Javascript:

var clickedArray = new clicked([], "b", "c"); 
// label is an array in this instance of your object
clicked1.label.push("xxx");

You can use getters/setters:

function clicked(lbl,name,value){
    var label=lbl;
    this.name=name;
    this.value=value;
    this.getLabel = function(){
        return label;
    };

    this.setLabel = function(lbl){
        label = lbl;
    };
}
