这是我的代码:
var Quo = function(string) { //This creates an object with a 'status' property.
this.status = string;
};
Quo.prototype.get_status = function() { //This gives all instances of Quo the 'get_status' method,
//which returns 'this.status' by default, unless another
//instance rewrites the return statement.
return this.status;
};
var myQuo = new Quo("confused"); //the `new` statement creates an instance of Quo().
document.write(myQuo);
当我运行此代码时,结果为
[object Object]
。由于get_status()
附加到Quo
prototype
,所以调用Quo
的实例是否足以调用该方法?我在这里错过了什么? 最佳答案
不应该是document.write(myQuo.get_status());
吗?
更新:
另一个选择是像这样覆盖toString方法:
Quo.prototype.toString = function() {
return this.status;
};
