PROBLEM TO BE SOLVED: To suppress the increase of a screen display time in the case of adding a new HTML (Hyper Text Markup Language) file and the increase of the processing time of a screen operation in JavaScript(R) by preventing a DOM (Document Object Model) tree size from increasing even when the number of panel caches increases concerning a screen switching control method for switching the screen of a plurality of HTML documents.SOLUTION: An HTML document is converted into DOM format data whose display processing is possible on a Web browser, and stored in a main memory as a hierarchically structured DOM tree, and DOM format data P1 of the HTML document to be displayed is constructed on the DOM tree to be handled on the Web browser so as to be displayed, and DOM format data P2 to P6 to be non-displayed are moved to DOM trees D1 to D5 constructed in in-line frames I1 to I5 so as to be non-displayed. In the case of switching a screen, the non-displayed DOM format data are moved from the DOM tree in the in-line frames to the DOM tree to be handled on the Web browser so as to be displayed. |
