Prototyping Problem (mehr Code)

[Markus**]

Bei diesem Code fehlt mir, wie vehicle aufgebaut ist. Ist route_arr prototypisch oder eine in der Initialisierung gesetzte Eigenschaft?

LX, danke für die schnelle Antwort,
hier mehr code:

  
  
function vehicle(id) {  
	this.id = id;  
	this.route_arr = new Array;  
	this.date = "";  
	this.company = "";  
	this.company_name = "";  
	this.gate = "";  
	this.status = "";  
	this.changed = "";  
	this.departure_time = "";  
	this.destination = "";  
}  
  
vehicle.prototype = document.createElement("div");  
  
vehicle.prototype.Route_name = function(value) {  
 if (value != null) {  
	this.route_arr.push(value);  
	this.destination = value;  
	}  
	else {  
	var temp = this.route_arr.shift();  
	this.route_arr.push(temp);  
	return temp;  
	}  
}  
  
vehicle.prototype.GetDiv = function() {  
	this.style.width = "30px";  
	this.style.height = "10px";  
	this.style.border = "1px solid #bfbfbf";  
	this.appendChild(document.createTextNode("Test"));  
	return this;  
}  
  
var t = new vehicle(1);  
  
t.departure_time = "03:15";  
t.company = "ABCZ-OB";  
t.company_name = "Test";  
t.Route_name("Test1");  
t.Route_name("Test2");  
t.gate = "10";  
t.status = "1";  
t.changed = "0";
