Question

我得到此错误，我将运行以下java文件。

 import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;

import javax.script.Bindings;
import javax.script.Invocable;
import javax.script.ScriptContext;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class TestForTheThread {
    public static void main(String args[]) {
        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("javascript");
        try {
             URL yahoo = new URL("http://localhost/XMLLoadProject/thiru.js");  
                URLConnection yc = yahoo.openConnection();  
                BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
                engine.eval(in);
        } catch (ScriptException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("fail to load");
        }catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("fail to load");
        }
        Invocable invocable = (Invocable) engine;
        Object result;
        try {
            result = invocable.invokeFunction("idplogurl", "thriu");
            System.out.println(result);
        } catch (ScriptException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
    }
}

示例js文件

var idplogurl = function(idpcode) {
    /*! jQuery v1.11.2 | (c) 2005, 2014 jQuery Foundation, Inc. | jquery.org/license */
   document.write('<script type="text/javascript" src="'+ idpcode+ '"></script>');
}

在javascript文件中（＆＃39; thiru.js＆＃39;）包含文档（javascript默认对象）。一些网站说用浏览器不可能。 任何人请对此错误提出质疑。 我收到了这个错误

javax.script.ScriptException：sun.org.mozilla.javascript.internal.EcmaError：ReferenceError：＆＃34; document＆＃34;没有定义。（＃17）在第17行

请帮助我任何人......

尝试使用此案例或驼峰案例

ScriptEngine engine = mgr.getEngineByName("JavaScript");
 or
ScriptEngine engine = mgr.getEngineByName("javaScript");

粘贴您的javascript代码

尝试this您可能会有所了解。

javax.script.ScriptException：sun.org.mozilla.javascript.internal.EcmaError：ReferenceError：＆＃34; document＆＃34;未定义
