Javascript object-based programming for C# object-oriented programmers

<script>

    
    function individual(msg) // class individual
    {
        this.mx = msg;    // mx is a public property of class individual instance
        var zuper = this.mx + '!'; // zuper is a private property of class individual instance
        
        this.show = function() { // public method
            alert(zuper);
        }
        
        this.showSomething = function() { // public method
            alert(this.something);
            quick();
        }
        
        function quick() { // private method
            alert('quick');
        }
    }

    var x = new individual("Hello");
    var y = new individual("World");
    
    alert(x.mx); // shows Hello
    alert(y.mx); // shows World
    
    alert(x.zuper); // shows undefined    
    y.zuper = "xxx"; // but this one creates a different instance of outside zuper on y's instance, but this is different from y's inside zuper
    alert(y.zuper); // shows xxx
    
    
    x.show(); // shows "Hello!"
    y.show(); // to prove that the outside zuper instance on y is different from inside(acts like a private property), this will not show "xxx", this shows "World!"
    
    y.something = "George"; // you can attach properties on javascript's object on whim
    y.showSomething(); // shows "George"
    
    y.quick(); // this will make javascript terminate silently
    alert("Not shown"); // won't get executed 
    
</script>

Put prefix to a property

<script>


String.prototype.splice = function( idx, rem, s ) {
    // sourced from: http://stackoverflow.com/questions/4313841/javascript-how-can-i-insert-a-string-at-a-specific-index
    return (this.slice(0,idx) + s + this.slice(idx + Math.abs(rem)));
};

String.prototype.putPrefixToProperty = function(prefix) {
    ndx = -1;
    for(i = this.length - 1; i > 0; --i) {
        if (this[i] == '.') {
            ndx = i;
            break;
        }
    }    
    return this.splice(++ndx,0,prefix)        
}


alert("ProductId".putPrefixToProperty("txt_"));
alert("PurchasedDto.ProductId".putPrefixToProperty("txt_"));
alert("PurchasedDto.LineItem.ProductId".putPrefixToProperty("txt_"));

</script>

Output:

txt_ProductId
PurchasedDto.txt_ProductId
PurchasedDto.LineItem.txt_ProductId

Trivia: Did you know you can copy alert's text(or any dialog for that matter) by pressing Ctrl+C
