The invention discloses a method for webpage caching of a terminal browser. The method comprises the following steps of loading a webpage, generating a DOM (document object model) tree and a Render tree corresponding to the webpage, and storing the DOM tree and the Render tree in a memory; generating an index object corresponding to the webpage, wherein the index object is used for indicating the storage addresses of the DOM tree and the Render tree corresponding to the webpage; storing the index object into an index list. The embodiment of the invention also discloses a device for the webpage caching of the terminal browser and a terminal. By adopting the method, the speed of the browser executing the webpage returning operation can be accelerated, the operation time is shortened, and the energy and electricity of the terminal can be favorably saved.
