Abstract

The invention is applicable to the technical field of browser interface extension, and provides a local extension method and system for a Javascript. The local extension method and system for the Javascript comprises the step of extending a management module by a browser layer, wherein the management module extends a Javascript file, and the browser layer loads the extended Javascript file of an extension layer; the step of calling Javascript natives packaged into a uniform API by the extended Javascript file; the step of providing a uniform calling interface for a standard layer by the uniform API. According to the local extension method and system for the Javascript, the extension layer is added between the standard layer and the browser layer, and therefore the natives of the browser layer can be packaged downwards, and the uniform calling interface is provided for the standard layer upwards; the development complexity is simplified; the maintenance cost is reduced; and the developing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of browser interface extension, in particular to a Javascript local extension method and system. Background technique [0002] In the field of web application development in the existing radio, television, Internet and other industries, most of the languages ​​selected for application development are Javascript. Calling the local method of the system through Javascript (hereinafter referred to as: native method) requires the browser to expand various methods according to the interface definition. System capabilities, that is, extending various native methods. These interfaces are defined differently. For example, many standards have been produced in the broadcasting industry: national standard NGB, Guangdong standard GCable, international standard HBBTV and other standards. Since various standards are not uniform, browsers need to perform localized interface extensions according to various standards. [00...
