javascript中的this
<script type="text/javascript">
var person = {
name:"Kevin Yang",
sayHi:function(){
alert("你好，我是"+this.name);
}
}
setTimeout(person.sayHi,2000);
</script>

[解决办法]
this 指 调用者的对象

setTimeout(person.sayHi,2000);
换成
person.sayHi();

就能正确了。
[解决办法]
你这里 this 指的是 window 对象

}
}
setTimeout(person.sayHi,2000);
</script>
