SELECTION LIST OBJECT GENERATING METHOD IN DYNAMIC MULTI-STEP ON SAME FRAME OF STATIC WEB DOCUMENT

摘要

PURPOSE: A selection list object generating method in dynamic multi-step on a same frame of a static web document is provided to decrease a loss of a storage space of a computer by generating several multi-step selection lists in one frame when generating two selected list objects or more. CONSTITUTION: A frame of a web is divided into a frame 1 and a frame 2(501). A width of the frame 1 is set as 100 percents of a width of all frame and a width of the frame 2 is set as 0 percent of the width of all frame(502). A main list and a sub list are generated in the frame 1(503). It is identified as to whether one element among the main list of the frame 1 is selected(504). A control is transmitted to the frame 2 when one element is selected(505). A cache of the frame 2 is deleted(506). A preprocessing controller of the frame 2 searches elements of the sub list dependent to the selected element of the main list of the frame 1(507). It is identified as to whether an element of the sub list is existed(508). A controller of the frame 2 deletes previous elements of the sub list of the frame 1 when the element of the sub list is existed(509). The controller of the frame 2 outputs searched elements to the sub list of the frame 1, deletes a cache stored in the frame 2 when controlling the preprocess, and returns the control to the frame 1(510,511).
