The method comprises the following steps of receiving a page loading request so as to obtain a corresponding template; loading the template; obtaining content data of a generated HTML file according to markers in the template; and finally inputting the content data into the template so as to generate an HTML file. In the process, the markers exist in the template in an HTML code annotation mode, so that an editor can prompt syntactic errors in HTML codes; even if the markers have errors, the template loading and the HTML file generation cannot be influenced; the occurrence of page 404 problems is avoided; and the goal of fast and accurately generating the HTML file is achieved.
