Realizing method of JavaScript extended object based on Android platform, and binding interface structure

Abstract

The invention provides a realizing method of a JavaScript extended object based on an Android platform, and a binding interface structure. The realizing method of the JavaScript extended object based on the Android platform comprises the following steps of: sending an attribute reading request to the binding interface of the JavaScript extended object of a Web application client by a browser engine according to the JavaScript extended object; calling a pre-set acquisition statement by the binding interface of the JavaScript extended object according to the attribute reading request and setting field name parameters of the acquisition statement to be an attribute name of attribute data to be acquired; and executing the acquisition statement and returning the attribute data which has the corresponding attribute name and is acquired from the Web application client back to the browser engine. According to the realizing method and the binding interface structure, the direct reading and value assignment of the attribute date of the Java object are realized so that the conditions for realizing more abundant extending function are created.

Description

technical field [0001] The invention relates to an Android platform-based JavaScript extension object implementation method and a binding interface structure, belonging to the technical field of intelligent terminals. Background technique [0002] The Android (Android) platform is an operating system platform of a smart terminal, which can be used in a smart phone or a set-top box. JavaScript is an object-based and event-driven client-side scripting language with relative security. JavaScript extension objects are object files written in the JavaScript language to extend new functionality for the browser. [0003] figure 1 It is a schematic diagram of the system structure of implementing a JavaScript extension object based on the Android platform in the prior art; as shown in the figure, the system mainly includes: a Web application client and a browser engine. JavaScript extension objects are added to the browser engine. Specifically, these JavaScript extension objects a...

[0005] The defect of the prior art is that the process of invoking the corresponding Java object according to the JavaScript extension object is realized through the JavaScript extension object binding interface of the Web application client

However, existing Java objects usually include two parts: process data and attribute data. The Android platform was originally designed only for mobile smart terminals such as mobile phones. The extension functions required for these application scenarios are limited, so only the JavaScript extension object binding interface The function of calling the process data of the Java object is designed, but the function of directly reading and assigning the attribute data is not designed; Direct reading and assignment, while the lack of functions in the existing JavaScript extended object binding interface limits the realization of extended functions
