我的代码如下：
<script language="javascript">
function Person(name, age){
this.name = name;
this.age = age;
this.say = sayFunc();
}
function sayFunc(){
alert(this.name+ ":" +this.age);
}
var person1 =new Person("张三",18);
person1.say();
</script>
运行结果this.name为空,this.age未定义
请问错在哪里?
<script language="javascript">
function Person(name,age){
this.name = name;
this.age = age;
this.say = function(){
alert(this.name + ":" + this.age);
};
}
var person = new Person("张三",18);
person.say();
</script>
this.name是批量sayFunc的name和age,所以会出错
我修改了一下:

var person1 =new Person("张三",18); person1.say() </script>
