jsp小网站源码

quot网站源码是什么意思

       网站源码,我们可以把它理成源文代码,源码就拿我们当前看到的网站这个网页来说吧,其实它是源码侠义道1源码由一大堆的源代码组成,通过我们的网站IE(Microsoft Internet Explorer)浏览器(或服务器)翻译成现在我们所看到的这个样子。网站源码也分为两种,源码一种是网站动态源码如:ASP,PHP,源码JSP,网站.NET,源码CGI等,网站易源码 查询系统一种是源码静态源码如:HTML等。什么是网站动态源码呢?最大的特点就是能够和用户之间互动。比如说网易的源码信箱,张三登陆的网站时候,会看到欢迎光临张三,咸鱼卖源码侵权李四又登陆了,李四又看到欢迎光临李四,其实他们两个人登陆的是一个页面,这个就是动态源码的好处,如果要是小说同步阅读源码用静态源码,好么网易有几百万的邮箱用户,每个人做一个页面那要多少页啊?动态源码不单单只有这么一点用处,比如说我们常见的一些论坛、留言本、计数器、成品网站源码韩国聊天室等,都是由动态源码开发的。什么是静态源码呢,比如说我们当前看到的这个网页他就是静态的源码,静态源码无法实现以上的那些功能。现在有不少源码下载站,提供别人开发好的源码让我们下载。他们开发的都不错,美工也相当不错,基本上下载下来,只要稍加改动就可以使用了,更方便了我们建站,您可以跟据自己所需去下载,更重要的是,要先看看您自己使用的网站空间,是那一种的,比如说您使用的是ASP空间,那么您一定要下载ASP源码,不然下载别的是不能运行的。。
