Functions that enumerate JavaScript objects:
Function iterator (obj ){
For (var property in obj ){
Document. writeln ("<p>" + property + ":" + obj [property] + "</p> ");
}
}
A simple example (test. js ):
Function Employee (){
This. name = "";
This. dept = "general ";
}
Function Manager (){
This. reports = [];
}
Manager. prototype = new Employee ();
Function WorkerBee (){
This. projects = [];
}
WorkerBee. prototype = new Employee ();
Function SalesPerson (){
This. dept = "sales ";
This. quota = 100;
}
SalesPerson. prototype = new WorkerBee ();
Function Engineer (){
This. dept = "engineering ";
This. machine = "";
}
Engineer. prototype = new WorkerBee ();
Engineer. prototype. specialty = "code ";
Function iterator (obj ){
For (var property in obj ){
Document. writeln ("<p>" + property + ":" + obj [property] + "</p> ");
}
}
