1. A method implemented by one or more computing devices, the method comprising: providing a page containing a plurality of objects, wherein the page includes a first region displaying multiple first-level categories and a second region displaying multiple second-level categories; obtaining a status of the objects; determining whether the status of the objects satisfies a preset condition; and performing an automatic switching control on; a current second-level category displayed in the second region by: determining whether the current second-level category displayed in the second region is a last second-level category of a plurality of second-level categories under a first-level category to which the current second-level category belongs, automatically switching to a next second-level category of the first-level category to which the current second-level category belongs in response to determining that the current second-level category displayed in the second region is not the last second-level category of the plurality of second-level categories under the first-level category to which the current second-level category displayed in the second region belongs, determining whether the first-level category to which the current second-level category belongs is a last first-level category of the multiple first-level categories in response to determining that the current second-level category is the last second-level category of the plurality of second-level categories under the first-level category to which the current second-level category belongs, and automatically switching to a next first-level category in the first region and switching to a first second-level category of the next first-level category in the second region in response to determining that the first-level category to which the current second-level category belongs is not the last first-level category of the multiple first-level categories, or a current first-level category displayed in the first region in response to determining that the status of the objects satisfies the preset condition.
