需要 rhino-1.7.7.jar 包

程式碼範例：

package cn.java.mozilla.javascript;import org.mozilla.javascript.Context;import org.mozilla.javascript.Scriptable;public class Test {    public static void main(String[] args) {        test4JsNormalCode();        test4JsObj();        test4JsFunc();        test4JsFuncWithParam();    }        protected static void test4JsNormalCode() {        Context ctx = Context.enter();        Scriptable scope = ctx.initStandardObjects();        String jsStr = "100*20/10";        Object result = ctx.evaluateString(scope, jsStr, null, 0, null);        System.out.println("result=" + result);    }        protected static void test4JsObj() {        Context ctx = Context.enter();        Scriptable scope = ctx.initStandardObjects();                String jsStr = "var objTest = { ‘key1‘:‘value1‘ }; objTest.key1;";        Object result = ctx.evaluateString(scope, jsStr, null, 0, null);        System.out.println("result=" + result);    }        protected static void test4JsFunc() {        Context ctx = Context.enter();        Scriptable scope = ctx.initStandardObjects();        String jsStr = "var testFunc = function(){ return ‘testFunc...‘ }; testFunc();";        Object result = ctx.evaluateString(scope, jsStr, null, 0, null);        System.out.println("result=" + result);    }        protected static void test4JsFuncWithParam() {        Context ctx = Context.enter();        Scriptable scope = ctx.initStandardObjects();        scope.put("param1", scope, "value1");        String jsStr = "var testFunc = function(param){ return ‘testFunc...‘+‘param=‘+param }; testFunc(param1);";        Object result = ctx.evaluateString(scope, jsStr, null, 0, null);        System.out.println("result=" + result);    }}

輸出結果

result=200result=value1result=testFunc...result=testFunc...param=value1
