Javascript variable set to a string

Question

Why does my this.pPos is set to a string containing the function code, instead of the function return value?

http://jsfiddle.net/SpGwL/

function game(mode, boardDim) {
 //mod
 this.mode = mode;
 //dim tabla
 this.boardDim = boardDim;
 //pozitii initiale elemente
 if (this.mode == 'easy') {
 //creez pozitii specifice 
 this.pPos = function () {
 var pPos = Math.floor(Math.random() * Math.pow(this.boardDim, 2));
 return pPos;
 };
 }
}
var asd = new game('easy');
alert(asd.pPos);

This should return a random number, but it returns the function's text.

• elclanrs: Because you're not calling the function, asd.pPos()

Answer 1

You have to call the function.

alert(asd.pPos());

Alerting the function itself will implicitly call toString() on it.

• salezica: +1, it's not text. It's just that Javascript gives you the function's code when you attempt to turn it into a string, like alert() does.
