METHOD FOR PRESERVING HISTORY OF HTML CONTENT

摘要

PROBLEM TO BE SOLVED: To use history data of contents by providing a means for holding data equivalent to the history of a user operation in an HTML file which is read in a second frame. SOLUTION: Operation keys 2 and 2a are for reading the prescribed HTML file into a first fame 1a with the click operation of a user. The prescribed HTML file is newly read instead of the HTML file which is displayed at present and a display content is switched by clicking the operation key 2 by the user. The second frame 1b is set to be different from the first frame 1a in such a way that the new HTML file is prevented from being read by the user operation when the prescribed HTML file is once read. The history of the file which is read into the first frame 1a is held in the HTML file which is read into the second frame 1b.
