js创建对象

<script language="javascript">
//1、无参函数new出来
  function Car(){
    var ōcar = new Object;
    ocar.color = "blue";
    ocar.doors = 4;
    ocar.showColor = function(){
      document.write(this.color)
    };
  return ocar;
  }
  var car = Car();


//2、有参函数new出来
 function Car(color,door){
    var ōcar = new Object;
    ocar.color = color;
    ocar.doors = door;
    ocar.showColor = function(){
      document.write(this.color)
    };
  return ocar;
  }
  var car = Car();


//3、直接创建实体对象

js中：

LODOP_OB = {
    id:"LODOP_OB",
    classid:"clsid:2105C259-1E0C-4534-8141-A753534CB4CA",
    width:0,
    height:0,
    LODOP_EM:{
        id:"LODOP_EM",
        type:"application/x-print-lodop",
        width:0,
        height:0,
        pluginspage:"install_lodop32.exe"
    }
};
alert(LODOP_OB.LODOP_EM.id);
