在创建对象时遇到麻烦。控制台说在最后一行有问题。请告诉我应该如何，我更熟悉Java，所以这对我来说有点困惑。
var dog = {
name:"Dog",
age:"11",
getName : function() {
alert(this.name);
}
}
function Dog(name, age) {
this.name = name;
this.age = age;
}
var d1 = new Dog("Rex", 8);
d1.getName();
JavaScript中的传统OO
function Dog(name, age) {
this.name = name || "Dog";// if the name is not given, it defaults to "Dog"
this.age = age || "11";
}
Dog.prototype.getName = function() {
alert(this.name);
}
var d1 = new Dog("Rex", 8);
d1.getName();
JavaScript中的更多显式面向对象
function createDog(name, age) {
// create a new dog and return it
var dog = {
name: name || "Dog",// if the name is not given, it defaults to "Dog"
age: age || "11"
};
return dog;
}
createDog.getName = function(dog) {
// explicit dog as 1st parameter
alert(dog.name);
}
//createDog is a normal function that returns something, no "new" needed
var d1 = createDog("Rex", 8);
createDog.getName(d1);
