疑惑：window.location='url' 与window.lcoation.href='url'效果一样，都会跳转到新页面，区别在哪？查得的资料如下：
1：window.location是页面的位置对象，window.location.href是 location的一个属性值，并且它是location的默认属性就是说对window.location直接赋值一个url实际上就是对window.location.href赋值2：
The Window.location read-only property returns a Location object with
information about the current location of the document.Though Window.location is a read-only Location object, you can also
assign a DOMString to it. This means that you can work with location
as if it were a string in most cases:location = 'http://www.example.com'is a synonym(同义词) oflocation.href = 'http://www.example.com'.
https://developer.mozilla.org/en-US/docs/Web/API/Window/location
location 是 location.href 的簡寫，無論是訪問 值 還是賦值。
從功能上，location 等於 location.href；
但從本體論上，location 是一個對象，location.href 是它的一個屬性。
這種怪異的行爲應該是爲了兼容無疑
