Abstract

The invention discloses a method and a device for implementing a local operation on a web page and belongs to the field of web technology. The method is applied to an electronic device that comprises a displaying unit and has an HTML operating environment. The method comprises the steps of: loading a web page in the HTML operating environment by address information; obtaining identification information for representing a status of local resources of the electronic device in the process of loading the web page; obtaining an operation request for representing a request for operating a first resource in the local resources; responding to the operation request with the first resource according to the operation request; and displaying a response result of the responding to the operation request with the first resource on the displaying unit. The device comprises a loading unit, an acquiring unit, a response unit and the displaying unit. According to the method and device, executing local operation on the web page is implemented, and local calling capacity of a javascript code is improved.

Description

technical field [0001] The invention relates to the field of web technologies, in particular to a method and device for realizing local operations on web pages. Background technique [0002] JavaScript is an object-based and event-driven client-side scripting language with relative security, which is widely used in client-side Web development. JavaScript is often used to add dynamic functions to HyperText Markup Language (English: HyperText Markup Language, abbreviation: HTML) web pages, such as responding to various user operations, etc. JavaScript can also be used in other occasions, such as server-side programming and so on. [0003] The JavaScript engine is an interpreter that can read and execute JavaScript source code, and is now mostly used in web browsers, such as Nitro in Apple Safari4, V8 in Chrome, TraceMonkey in Mozilla Firefox3.5, and so on. [0004] In the Chrome browser, Javascript engine V8 is responsible for parsing and running Javascript code. Among them,...
