Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式举行繁杂的编程。以下是我为大家探寻整理的从零码起调用javascript，梦想能给大家带来扶助!更多精彩内容请实时关注我们我!

packageco.test;

importjava.io.FileReader;

importjava.io.LineNumberReader;

importorg.mozilla.javascript.Context;

importorg.mozilla.javascript.Function;

importorg.mozilla.javascript.Scriptable;

privateContextcx;

privateScriptablescope;

publicJSExploration

this.cx=Context.enter;

this.scope=cx.initStandardObjects;

publicObjectrunJavaScriptStringfilename

StringjsContent=this.getJsContentfilename;

Objectresult=cx.evaluateStringscope,jsContent,filename,1,null;

returnresult;

reader=newLineNumberReadernewFileReaderfilename;

Strings=null;

StringBuffersb=newStringBuffer;

whiles=reader.readLine!=null

sb.appends.append\n;

returnsb.toString;

Stringfilename=System.getPropertyuser.dir+/jsmap.js;

JSExplorationjsExploration=newJSExploration;

Objectresult=jsExploration.runJavaScriptfilename;

Scriptablescope=jsExploration.getScope;

Functionsum=Functionscope.getsum,scope;

FunctionisPrime=Functionsum.callContext.getCurrentContext,scope,sum,newObject[]2,8;

Objectss=isPrime.callContext.getCurrentContext,sum,isPrime,newObject[]2,8;

System.out.printlnContext.toStringss;

试验了一个java调用javascript的例子，假设把jsmap.js中的.与this有关的代码注销的话程序就可以正常运行。不住销掉的话就会报个运行时错误。。。

js代码如下有关this的代码已注销：

functionsumx,y

//this.formulaeObject=null;

//this.formulaeObject[vager]=functionc,d
