Why does location.toString() report the same as location.href?
提问by Dean James
The window.location is an object. But when you execute location.toString()it converts the object to the equivalent to location.href.
window.location 是一个对象。但是当您执行location.toString()它时，它会将对象转换为location.href.
My question is how? And can I set up objects to a similar behaviour?
我的问题是如何？我可以将对象设置为类似的行为吗？

You can add a toStringmethod to your object that returns what you want. In that case href
您可以toString向对象添加一个返回所需内容的方法。在这种情况下href
eg:
例如：
var obj = {
href:'',
toString:function(){
return this.href;
}
};
obj.href = 'http://stackoverflow.com';
obj.toString();
