Engine instance, you can easily execute the script language. By convention, we start with a simple hello World: Public class runjavascript {Public static void main (string [] ARGs ){Scriptenginemanager factory = new scriptenginemanager ();Scriptengine engine = factory. getenginebyname ("JavaScript ");Engine. eval ("Print ('Hello World ')");}} This Java code will execute JavaScript and print out Hello world. What if a syntax error occurs in JavaScript

Such as Copy Code code as follows: public void greet () throws Scriptexception { Scriptenginemanager manager = new Scriptenginemanager (); ScriptEngine engine = Manager.getenginebyname ("JavaScript"); if (engine = = null) { throw new RuntimeException ("Cannot find JavaScript language execution engine"); } Engine.eval ("println (' Hello ');"); } It can a

easier to operate. In addition, the script engine includes Error events and Timeout events, which can be registered based on actual usage. II. The script engine demonstrates that I have created a form program to test whether to enable the AllowUI attribute, set the timeout time, and select a method for calling the script engine. The code of the test program is long. The following lists the main parts: using System; using System. drawing; using System. collections; using System. componentModel;

implement javax.script.ScriptEngine (for simplicity, can inherit Javax.script.AbstractScriptEngine) and javax.script.ScriptEngineFactory two interfaces. Of course, before you implement your own scripting language engine, go to scripting.dev.java.net project to see if someone has helped you do your job, so you can use it directly. Scripting APIThe Scripting API is an API for scripting language programs in Java, where the Scripting API is found in Javax.script, and we use this API to write JavaS

Build your own C # script with RoslynIn the next generation of C #, an important feature is the "Compiler as a service", which simply means that the compiler is opened up to one that can be invoked in code. Recently used the Microsoft release of the Project Roslyn CTP version, feeling is very powerful.To execute a C # script in your own code, start with the following steps. Download the Roslyn CTP version and install it on the Microsoft website Add references to Roslyn.Compilers.dll

Also does not jump out of time reminders of the dialog box, vice versa; Reset the Language property clears the Addcode-loaded code; For the Timeout property, the ScriptControl examines the object's Allowui properties when a timeout occurs.

Description of the Script API running on JVM, jvmscriptapi descriptionBasic API description Other languages can be executed on jvm. A script engine is required to execute other languages. JDK provides related APIs. This API is suitable for any language that can run on the JVM. · ScriptEngine is a script execution engine used to execute specified scripts. Based on several eval rewriting forms, you can know that it can be used to execute a script in

JAR service discovery mechanism. It is possible-drop any JSR-223 compliant script engine in the CLASSPATH and access the same from your Java application S (much like JDBC drivers, JNDI implementations is accessed).So we can either use the JSR223 API to execute the script or, of course, execute it directly using the API provided by the scripting language. Let's look at the following separately.JSR-223by Scriptenginemanager#getenginebyname This API we can get a script engine that implements JSR-2
