Abstract: A system information transmitting method and apparatus, and a computer-readable storage medium are provided. The method includes receiving, at a terminal, a system call instruction sent by a browser, acquiring, at the terminal, target system information according to the system call instruction, dividing, at the terminal, the target system information into at least one data set, obtaining, at the terminal, encoded pseudo-touch event information by encoding the at least one data segment in the target system information according to a positional relationship of respective touch points in a simulated pseudo-touch event in a touch plane, and transmitting, from the terminal, as an input parameter of the target script, the encoded pseudo-touch event information to the target script through the browser.

Abstract: Provided is an apparatus for communication between a webpage and an operating system. The apparatus includes memory storing a first software for an operating system and a second software for a web browser. The apparatus also includes processing circuitry that executes the first software to provide the operating system including a clipboard and executes the second software to cause the web browser to access a web page. Further, a software (the first software or the second software) executed by the processing circuitry detects a message that is buffered in a clipboard provided by the operating system, and determines whether the message is in a preset format that is indicative of the software executed by the processing circuitry being a destination of the message. The software executed by the processing circuitry then processes the message when the message is in the preset format.
