Function As Object

[Drycodez 4]

function a(){}a.name="You"a.age;alert(a.name)//prints: 'You'.

is it a good idea to defined object this way?

Only if you actually need to have properties on a function.

I learned that when doing what you did Sam, that's what's considered a 'constructor' for an object in JavaScript.

Yeah, but its still an object. Using the " new" keyword, just create a clone (copy/instance/prototype).

Mmm.. it does not make much sense. Maybe if you put some prototype function in the function (constructor) like this:

function a(name,age){  this.name = name;  this.age = age;}a.prototype = {   alert:function()   {	   alert(this.name+" is "+this.age+" years old")   },   giveAge:function()  {	 return this.age;  }};var me = new a("eric",25);me.alert();//shows eric is 25 years old 

Then you can make multiple a's, and they have all the same functions. If you just want make object for holding vars, you can als do this:

 //Like this:var a = {name:"eric",age:25}; //or like this: var a = {}; a.name = "eric";a.age	= 25;
