| 在java代码中还可调用javascript函数和方法调用函数package test;
/** * * @author hongrui xing */import javax.script.*;
public class InvokeScriptFunction { public static void main(String[] args) throws Exception { ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName("JavaScript");
// JavaScript code in a String String script = "function hello(name) { print('Hello, ' + name); }"; // evaluate script engine.eval(script);
// javax.script.Invocable is an optional interface. // Check whether your script engine implements or not! // Note that the JavaScript engine implements Invocable interface. Invocable inv = (Invocable) engine;
// invoke the global function named "hello" inv.invokeFunction("hello", "邢红瑞!!" ); }}使用OOP机制,调用并得到返回值package test;
/** * * @author hongrui xing */import javax.script.*;
public class InvokeScriptMethod { public static void main(String[] args) throws Exception { ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName("JavaScript");
// JavaScript code in a String. This code defines a script object 'obj' // with one method called 'hello'. String script = "var obj = new Object(); obj.hello = function(name) { return name+'红瑞'; }"; // evaluate script engine.eval(script);
// javax.script.Invocable is an optional interface. // Check whether your script engine implements or not! // Note that the JavaScript engine implements Invocable interface. Invocable inv = (Invocable) engine;
// get script object on which we want to call the method Object obj = engine.get("obj");
// invoke the method named "hello" on the script object "obj" Object ob=inv.invokeMethod(obj, "hello", "hello" ); System.err.println(ob); }} |
