The invention discloses a page and control increasing method based on a WEB. The method includes the steps of (1) increasing node pages, (2) increasing controls, and (3) displaying the pages, wherein in the first step, a controller sends a client request to a tree menu management module, a JDBC interface is called, and a template is selected to be stored in a portal base table in a relation library; in the second step, the controller sends the client request to a control management module, and the control management module stores a node id and a column parameter in the portal base table in the relation library through JDBC; in the third step, the controller sends the client request to the control management module and the tree menu management module, control information and service data are obtained through data access management, and instantiation of the pages is achieved. The method achieves web online operation, and on the basis that safety requirements of a power system are met, measurement point information in a real-time database and service lists and the portal base table in a relation database can be displayed in real time.
