javar script到底是什么

我学习jQuery和ajax的过程中,知道jQuery是一个js库,
了解异步通信本质是通过js的XMLHttpRequest对象实现的。

为什么js能实现异步通信,js和浏览器,网络通信有啥关系?

搜索了很多答案,越来越搞不懂js到底是什么了,感觉js无所不能的样子。

假如我想了解js和整个web相关的体系结构,应该看哪本(哪几本书)!!

我是个野路子出身的,好不容易搞懂了C# .net,学到ajax, 虽然会写,基本明白。

但对于更深的理解脑袋里有一万个为什么在飘。

求教各位兄台指点迷津!

本质上说,任何图灵等价的编程语言(包括C#、汇编、机器语言、Basic、Java,也包括js)都是“无所不能”的。没有任何事情是js能做,而机器语言不能做的(虽然基本的x86指令只有100多条,根本没有什么面向对象,也没有面向过程)。
这个道理很浅显,无论什么语言,最后都是转换成机器语言执行的。但是反过来,有个牛人用js写过一个x86的模拟器,虽然速度很慢,但是可以运行linux这样完整的操作系统,这又说明没有什么机器语言能做而js做不到的事情。

js是一种编程语言,其实js是俗称,应该叫ecmascript,一种解释执行,多范式的脚本语言。在我上小学六年级以前,一直以为js=java。

我想在script里嵌套JAVA语句,接收从另一个页面传来的变量,然后根据他来决定下面的一个span的显示方式 其实就是想通过JS做一个分页的上一页下一页的显示,比如在第一页的时候,上一页的链接隐藏,当只有一页的时候,上一页下一页都隐藏,最后一页的时候下一页隐藏,就是这种效果 大致的代码如下,请问该怎么改怎么,两个从request中取的值都是可以取到的,已经在下面当前页数:X / Y显示了,但是这段代码没有达到预期效果 <head> <script> var oSpan1=getElementById("span1"); var oSpan2=getElementById("span2"); var index=<%=Integer.parseInt(request.getAttribute("index").toString())%> var totalPage=<%=Integer.parseInt(request.getAttribute("totalPage").toString())%> if(index==1&&totalPage==1) { oSpan1.display="none"; oSpan2.display="none"; } else if(index==1Page&&totalPage!=1) { oSpan1.display="none"; oSpan2.display="span"; } else if(index==totalPage&&totalPage1=1) { oSpan1.display="span"; oSpan2.display="none"; } else { oSpan1.display="span"; oSpan2.display=span"; } </script> </head> <body> 当前页数: <%=request.getAttribute("index") %>/ <%=request.getAttribute("totalPage") %> <br/> <span id="span1"><a href="first?index=<%=Integer.parseInt(request.getAttribute("index").toString())-1%>">上一页</a></span> <span id="span2"><a href="first?index=<%=Integer.parseInt(request.getAttribute("index").toString())+1%>">下一页</a></span> </body>

elFinder java connector的使用方法
想将elFinder文件管理器与java后台程序连接,发现已经有人写了elfinder-servlet作为elFinder的java连接器,看了他的使用说明,自己也尝试了和多次,但是就是没有成功啊... 按照使用说明,可以将这个连接器作为一个jar包引入,自己写两个类继承java连接器中的两个抽象类,直接运行这个工程,访问servlet就应该显示elfinder的界面,但是不管用。。。后来又自己写了个jsp页面,但显示没有连接到backend... jsp页面代码: <html> <head> <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/smoothness/jquery-ui.css" /> <link rel="stylesheet" type="text/css" href="http://elfinder.org/demo/css/elfinder.min.css" /> </head> <div id="elfinder"></div> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" ></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js"></script> <script src="http://elfinder.org/demo/js/elfinder.min.js" ></script>​ <script type="text/javascript"> $().ready(function() { var f = $('#elfinder').elfinder({ url : '/MyDemoServlet' }).elfinder('instance'); }); </script>​ </html> 运行后就显示Unable to connect to backend elfinder-servlet源码及说明网址: <https://github.com/Studio-42/elfinder-servlet>
JAVA POST登录异常问题?
网上找的HTTP登录代码,登录后返回能200,但是不用用户名密码也返回200,且用Cookie[] cookies = httpClient.getState().getCookies(); StringBuffer tmpcookies = new StringBuffer(); for (Cookie c : cookies) { tmpcookies.append(c.toString() + ";"); System.out.println("cookies = "+c.toString()); } 能取到Cookies,这个搞不懂 登录成功后跳到另一个网页,但是用System.out.println("ResponseBody:\n" + stringBuffer.toString());返回如下: ``` <html> <head><title></title> <SCRIPT LANGUAGE="JavaScript"> var currentWindow = window; if(currentWindow != null){ currentWindow.top.location = "/NMMP/jsp/login.jsp"; } </SCRIPT> </head> ``` 感觉跳转时少了东西,所以跳转后的网页不对,请各们大神帮分析下,或者给个思路,本人不是搞程序的,只是想做一个来应对自己的重复工作,完整代码如下:本人无C币,如果有兴趣帮我做可商量 ``` import java.io.BufferedReader;
