The invention provides a dynamic expanding method and a system for an embedded browser JavaScript interface. The method comprises the following steps that: step 1, the browser expands an application support interface, an application library loading interface and an application library unloading interface of a JavaScript engine in a static manner; step 2, a service provider develops a plurality of application interfaces required by services of the service provider and compiles codes of developed interfaces into dynamic library files in a binary form, and stores the dynamic library files in a memory of the browser through the application library loading interface; and step 3, when the browser parses the application support interface in a page frame, and searches for entrance addresses of the application interfaces of the service provider in the memory of the browser by the interface, if so, executing a program of the application support interface to dynamically expand the JavaScript interface of the browser based on the services. The application support interface is the JavaScript interface expanded by the browser for searching for the entrance addresses of the interface program with an appointed interface name. If the entrance addresses are found, the application interface is expanded.

The invention discloses a service rule engine execution system and method. The system comprises a SpringBoot framework and a Mysql database, the SpringBoot architecture comprises a Drools rule engine,a Javascript engine and a database operation layer, the Drools rule engine and the Javascript engine are connected with the Mysql database through the database operation layer; scripts of corresponding rules are stored by using the Mysql database, the corresponding rule scripts are obtained from the Mysql database when a request is received, whether the corresponding rules belong to the Drools rule engine or a Javascript engine is judged, then corresponding interpretation execution is performed, and corresponding contents are returned. According to the system and the method, calling in a Springed Cloud Feign mode is supported, and the influence on calling codes is small when service rules and corresponding data models are changed; and no additional component dependence is required.

The invention belongs a dynamic compiling and executing method of a JavaScript engine of an embedded browser, and the method comprises: creating and expanding a combined cache region, compiling a script hot point and an abstract syntax tree, scanning the abstract syntax tree, compiling byte codes and target codes, executing a script and determining and compiling a hot point region. According to the invention, the hot point scanning process is performed in front of the process of converting the abstract syntax tree into byte codes in a dynamic compiling mode in the JavaScript engine of the embedded browser and the advantages of fast explanation and execution response speed and high JIT execution efficiency are fully combined to further detect the hot point beyond the circulating structure in the explanation and execution process. Therefore, the method has the advantages of effectively improving the synchronism and efficiency of dynamic compiling of the JavaScript engine of the embedded browser and the JavaScript script operation, shortening the delay time between the dynamic compiling and executing, quickly executing the JavaScript script, updating the information displayed on a webpage in time and effectively improving the utilization effect of the user.

The invention provides a method and a device for rewriting a browser pop-up box by an external application program. The method includes: monitoring and capturing messages thrown by a Javascript engine of a browser; transmitting the captured messages to the external application program; interrupting transmission of a message, requiring modification of a browser interface by the external application program, in the captured messages thrown by the Javascript engine so as to disable the browser to redraw a UI (user interface) which is related to the message requiring modification of a browser interface by the external application program; allowing the external application program to redraw the UI according to the messages thrown by the Javascript engine; after the external application program finishes redrawing the UI, returning to execution flow of the Javascript engine of the browser, and allowing the browser to continue operating. The compatibility problem of the browser can be overcome, and modification of the browser interface is simpler.
