这个url的正则表达式判断的JavaScript!比较全面的。它验证的情况包括IP,域名(domain),ftp,二级域名,域名中的文件,域名加上端口!用户名等等信息,貌似作者也是在网上找的,我从一个项目代码中扣出来的,是我见过的最强最全面的url验证方式!太猛了,贴在这里与大家分享,URL的验证实在是很频繁。

function IsURL (str_url) { var strRegex = '^((https|http|ftp|rtsp|mms)?://)' + '?(([0-9a-z_!~*/'().&=+$%-]+: )?[0-9a-z_!~*/'().&=+$%-]+@)?' //ftp的user@ + '(([0-9]{1,3}.){3}[0-9]{1,3}' // IP形式的URL- 199.194.52.184 + '|' // 允许IP和DOMAIN(域名) + '([0-9a-z_!~*/'()-]+.)*' // 域名- www. + '([0-9a-z][0-9a-z-]{0,61})?[0-9a-z].' // 二级域名 + '[a-z]{2,6})' // first level domain- .com or .museum + '(:[0-9]{1,4})?' // 端口- :80 + '((/?)|' // a slash isn't required if there is no file name + '(/[0-9a-z_!~*/'().;?:@&=+$,%#-]+)+/?)$'; var re=new RegExp(strRegex); //re.test() if (re.test(str_url)) { return (true); } else { return (false); } } 

代码二:

function CheckUrl(str) { var RegUrl = new RegExp(); RegUrl.compile("^[A-Za-z]+://[A-Za-z0-9-_]+//.[A-Za-z0-9-_%&/?//.=]+$");//jihua.cnblogs.com if (!RegUrl.test(str)) { return false; } return true; } 

代码三:

function checkUrl(urlString){if(urlString!=""){var reg=/(http|ftp|https):////[/w/-_]+(/.[/w/-_]+)+([/w/-/.,@?^=%&:/~/+#]*[/w/-/@?^=%&/~/+#])?/;if(!reg.test(urlString)){alert("不是正确的网址吧,请注意检查一下");						}					}}

下面给大家分享一个常用的验证网址的正则表达式
