//采用call方式实现js继承
function A(color) {
this.Acolor = color;
this.AshowColor = function() {
document.writeln("Acolor: " + this.Acolor);
}
}
function B(color, name) {
A.call(this, color);
this.Bname = name;
this.BshowName = function() {
document.writeln("Bname: " + this.Bname);
}
}
var objA = new A("red");
objA.AshowColor();
document.writeln("----------------");
var objB = new B("black", "demo");
objB.AshowColor();
objB.BshowName();
document.writeln("----------------");
