window.location.hash returns hash tag in front of value

Question

I have the following code in MVC3 view:

 $(document).ready(function () {
    if (window.location.hash) {
        var manager= new Manager();

        manager.doSomeStuff(window.location.hash);
    }
});

The interesting thing is that when there is no hash tag in the URL, or there is only a hash tag example:

http://localhost:1223/Index/AboutUs

http://localhost:1223/Index/AboutUs#

When the window.location.hash is empty and the function is not executed. But when there is some value in the hash tag:

http://localhost:1223/Index/AboutUs#categoryId=5&manufacturerId=8

The value in the window.location.hash is #categoryId=5&manufacturerId=8

Can you explain to me why the # tag is included in the value and why when there is no value after the # tag, the window.location.hash is empty.

Answer 1

There's nothing much to explain. It is the way it works.

The hash property returns the anchor portion of a URL, including the hash sign (#).
