The invention provides a HTML interface control paste tool with an attached data processing function interface of a maintenance information system which business staff can design on their own and use. The tool adopts a visual mode of operation, can freely produce tables, floats or block area combinations in an absolutely positioned layout. The block areas are the container of the business elements, can be associated through the mode of reusing the existing interface control or be associated through the mode of dragging the business elements to the selected block area, the two modes both produce their own specific tags in the block areas. The block areas can adopt basic controls, such as pictures, text controls, and the like to describe and modify, can also adopt the appearance design such as borders, background color, font, size, and the like. The produced designing scheme is a description of the combination sequence of each HTML element that contains specific tags, and generates the page codes using the description, and dynamically compiles the codes for work use by the business staff. The business staff complete the interface development on their own, which greatly reduces the overhead costs.
