hi friends,
i went through "Douglas Crockford" book "Javascript : The good parts"
and i rearranged the code as below and it worked,
(function(){
var personProto = {
describe : function(){
alert("NAME IS "+this.name);
}
};
if(typeof Object.createObj !== 'function'){
Object.createObj = function(protoOfObj){
var F = function(){};
F.prototype = protoOfObj;
return new F();
};
}
var jane = Object.createObj(personProto);
jane["name"] = "JANE";
var tarzan = Object.createObj(personProto);
tarzan["name"] = "TARZAN";
jane.describe();
tarzan.describe();
})();
Thoughts on it please ,
waiting for the reply
