VBasic和VbScript，java和javaScript是什么关系
它们之间最大的关系就是语法很相似。VBaisc和VBscript的关系很明显，同样是微软的产品，VBscript的全称是Microsoft Visual Basic Scripting Edition，所以可以把Vbscript看作是Vbasic的简化版本，减少了许多功能。这只要是想把它作为一个脚本语言上的考虑。由此，它们的语法相同，内置函数的用法也一样。java与Javascript之间的关系就比较浅了。JavaScript是由Netscape公司开发的脚本语言。最出叫Mocha，后来改称LiveScript,随之Java走红，紧接着Netscape公司引进sun的有关概念，将其改为JavaScript。JavaScript是一种紧缩的基于对象的描述语言，用于客户端和服务器端Internet应用程序的开发。嵌入在Web页面中的JavaScript语句能够实别和响应鼠标单击、表单输入、页面浏览等拥护事件。一般不需要编译，由浏览器解释执行，不需要特殊的开发环境，用普通文本器即可进行。JavaScript不能对硬盘进行写入或者改写工作，也不会传播和病毒程序，使用JavaScript绝对安全。 不过可以说的是java与javascript之间的语法很相似，但不像vbasic与vbscript那么亲密。它们的出身本来就不同。
为什么用mocha测试的时候提示说nodejs版本过低
目前node的发布版本为：稳定长期支持版本：6.10；开发预览版本：7.9。看下你机器上的node版本是多少，一般都用稳定版，如果低于6.10就下载最新稳定版安装下，应该能解决。如果是Windows XP系统，那就不用折腾了，node已经停止对Windows XP的支持（当然你可以看下mocha支持的最低node版本是多少，5.x版本的话，XP应该还是能用的，具体可以到node官网查）。
mocha界面为什么和别人的不一样
版本的原因吧。这是跟踪软件mochapro的教程，是做一些ae特效的必备插件，是现在最流行的JavaScript测试框架之一，在浏览器和Node环境都可以使用。mocha工具栏每个工具的用法，这边要通过创建X样条工具来选择跟踪的范围，点击S是显示平面曲面，调整替换的范围，其他都是辅助选择的工具。
javascript用什么开发工具
JavaScript自推出后就大受开发者的青睐，基于JavaScript的开发工具（这里包含大量的JS开发资源，包括前端、框架、通用类等）不计其数，开发者们可以灵活选择，轻松构建应用。本文分享十款JavaScript开发工具1. Kreate这款工具有助于对 jQuery对象快速生成DOM。你可以创建单个或多个元素。 2. Night Watch jsNightwatchjs拥有一个简洁而强大的语法，能够允许你快速编写测试。它是专用于浏览器应用和网站的一款端到端的测试解决方案。 3. GulpjsGulp是比较火的开源项目，配置更简洁、更直观，受到很多开发者的青睐。4. Easy StarjsEasystarjs是利用 JavaScript API编写的，常用语构建HTML5游戏。开发者可以将其与现有的JS框架搭配使用。 5. Headroom.jsHeadroom.js 是一款轻量级、高性能的JS组件（无依赖性）。6. HarpjsHarp是一款快速的、轻量级的Web服务器。Harp serves Jade，Markdown，EJS，CoffeeScript, Sass, LESS以及Stylus as HTML、CSS & JavaScrip均可轻松配置。 7. Gantt TwprojectTwoproject是一款在线免费的JS开发工具，基于jquery创建而来，拥有强大迷人的特性，包括CSS皮肤样式、资源等。8. MochaMocha是一款功能丰富的JavaScript测试框架，可基于node.js及浏览器运行，它使异步测试变得更为简单有趣，支持灵活且准确的输出，捕捉异常现象。 9. Responsive NavResponsive Nav是一款轻量级的插件，帮助你为小屏幕创建连接导航。支持为移动设备创建触摸交互设计以及CSS转换等特性。 10. File API
java设置servletoutputstream的文件名字
1. 核心代码//设置Mime-Typeresponse.setContentType("application/msword");//设置下载默认文件名response.setHeader("Content-Disposition", "attachment;filename=123.doc");登录后复制完整代码public R《Object》 download(@PathVariable String id, HttpServletResponse response) { File uploadFile = new File(id + ".doc"); //获取后缀名 String suffix = uploadFile.substring(uploadFile.lastIndexOf(".")); String responseType = ResponseTypeUtils.getResponseContentByType(suffix); response.setContentType(responseType); response.setHeader("Content-Disposition", "attachment;filename=" + System.currentTimeMillis() + suffix); //输入流,通过输入流读取文件内容 try (FileInputStream fileInputStream = new FileInputStream(uploadFile)) { ServletOutputStream outputStream = response.getOutputStream(); int len; byte; while ((len = fileInputStream.read(bytes)) != -1) { outputStream.write(bytes, 0, len); //刷新一下 outputStream.flush(); } //关闭资源 outputStream.close(); return R.ok(); } catch (Exception e) { throw new RuntimeException(e.getMessage(), e); } }登录后复制当然也可以通过NIO的方式实现代码，具体可参见HttpServletResponse 返回图片的几种方法对比，核心代码如下：fis.getChannel().transferTo(0,fis.available(),Channels.newChannel(response.getOutputStream()));登录后复制3 参考状态码文件扩展名Content-Type(Mime-Type)文件扩展名Content-Type(Mime-Type).*（
