Abstract: An operation instruction for a hyperlink object is received. The hyperlink object is associated with a hyperlink. A determination is made as to whether a predetermined event exists when the operation instruction is received. The predetermined event is different from the operation instruction. In response to determining that the predetermined event does not exist when the operation instruction is received, a first page corresponding to the hyperlink is redirected to. In response to determining that the predetermined event exists when the operation instruction is received, a second page associated with the predetermined event is determined, and the second page is redirected to. The second page is different from, and associated with, the first page.

Abstract: A page request is received from a browser. A page script corresponding to the page request is allocated from a plurality of page scripts corresponding to the page request. The page script is transmitted to the browser for generation of a script execution parameter by execution of the page script by the browser. A page verification request is received from the browser, where the page verification request includes the script execution parameter. Whether a page verification request is expired is determined, where if the page verification request is expired, generating error prompt information indicating a page expiration. If the page verification request is not expired, whether the script execution parameter is valid, is determined. If the script execution parameter is valid, the validity is indicated, otherwise the page request is rejected.

Abstract: The present application provides two-dimensional code (2D-code) scanning interaction methods and apparatuses. An exemplary 2D-code scanning interaction method may include scanning a 2D code to obtain a first 2D-code value corresponding to the 2D code. The method may also include obtaining a second 2D-code value corresponding to the first 2D-code value. The first 2D-code value is generated in accordance with the second 2D-code value, and is corresponding to the second 2D-code value. The method may further include calling an application corresponding to the second 2D-code value and opening the second 2D-code value for interaction through the application.

Abstract: One embodiment provides a system that facilitates control of the display direction of content on a device. During operation, the system receives, by a client computing device, a first command to lock a state of a display for the device. The system sets a current display state to a locked state. In response to receiving a second command to terminate the first command, the system sets the current display state to a state that is the display state prior to receiving the first command. The system detects a change in a position of the device. In response to determining that the current display state is an unlocked state, the system changes a display direction for content displayed on the device. In response to determining that the current display state is the locked state, the system refrains from changing the display direction for content displayed on the device.
