The invention particularly relates to a terminal page turning and data keeping method. The terminal page turning and data keeping method comprises the steps of firstly, establishing a parent page andthree sub-pages, namely a head sub-page, a main body sub-page and a bottom sub-page, and introducing the three sub-pages into the parent page; then, packaging global data acquisition and assignment methods in the parent page, and adding opening and canceling of a page switching loading waiting effect; and finally, packaging a parent page data acquisition and assignment method in the main body sub-page, and packaging an opening and canceling method of a page switching waiting loading effect in the parent page. The terminal page turning and data keeping method is easy to implement, safe and reliable, can meet and be applied to various terminals which use browser kernels to achieve service functions, has no performance limitation, facilitates transformation and expansion of various services,can achieve efficient local service data reading and writing, improves page conversion efficiency and page transition friendliness.Therefore, the system development cost is reduced, and the user experience is improved.
