You are trying to show the gif in your current page. But when you set location.href its current content get destroyed and wait for the next content. When your current content get destroyed. So, your attempt to show loading in the current page will not work. May be there is work around. But I don't know.

To which control or html element you are trying to apply ".loading" css class? I do not see any html element with the class name.
