The invention provides an interactive-interface fast implementation method based on a reusable library. The interactive-interface fast implementation method comprises correlating data and interface elements by virtue of active data / view model design, constructing a reusable basic element library, a universal function library and a special function library according to the characteristics of an interactive interface and then constructing a reusable library, and finally raising model into-library standard specifications, thereby providing a unified standard interface a configuration path, a database table from and a data / view model binding specification. The method is suitable for a development platform based on remote access of WEB and based on local interactive interfaces of tools such as QT and VS; the method is capable of realizing various types of interfaces needing to be interacted based on the reusable library, and has the characteristics of simple function library design rule, high reusability, quick interface molding and the like; besides, the effectiveness of the reusable library and the usability of the interactive interfaces can be further improved by improving and optimizing the standard specifications of the reusable library.
