The invention discloses a webpage programming information transmission method, device and system, and relates to the field of the Internet. The problem that the webpage programming information with large information content cannot be transmitted cross a browser through a url is solved. The method comprises the following steps: a first browser converts to-be-transmitted webpage programming information into a unique corresponding character string and creates a unique corresponding character sign for the character string, writes the character sign in the url to transmit to a second browser, and sends corresponding character string to a server to save at the same time, and the server generates the unique corresponding character sign; the second browser reads the character sign in the url and sends the character sign to the server; the server compares with the received character sign with a generated character signal, and sends the unique corresponding character string of the same character sign to the second browser; and the second browser converts the received character string into the unique corresponding webpage programming information. The method disclosed by the invention is mainly used for the cross-browser transmission process of the webpage programming information.
