使用ip和http进行jquery验证 [英] jquery validation with ip and http

问题描述

我有一个人们可以输入其IP的字段.因此，我尝试使用jquery验证该字段:

I have a field where people enter their IP. So I try to validate that field with jquery:

$.validator.addMethod("http-ipvalidation", 
    function(value, element) {
        return /^[\d.]+$/.test(value);
    }, 
   "Sorry, only numbers and dots allowed here"
);

但是有些人正在使用DynDNS，然后可以使用url.所以现在我需要允许两者.有没有办法将默认的jQuery URL验证与我的自定义IP验证结合在一起?

But some people are using DynDNS which can then use an url. So now I need to allow both. Is there a way to combine the default jquery url validation with my custom IP validation?

我可以更改jquery url检查，但是这个正则表达式很疯狂，所以我不知道从哪里开始:

I could alter the jquery url check but this regex is crazy, so I wouldn't know where to begin:

return /^(https?|ftp):\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i.test(val);

另外，我认为允许人们在没有http(s)://的情况下进入也很好.因此，总而言之，我想创建一个验证，用户可以在其中输入:

Plus I think it would be nice to allow people to enter without the http(s):// as part of it. So to summarize I want to create validation where users can enter:

12.34.56.78或my.domain.com或http://my.domain.com

也许，我应该做一个简单的验证来取出一些特殊字符，然后保留它?预先感谢.

Perhaps, I should just take a simple validation to take out some special characters and leave it at that? Thanks in advance.

推荐答案

我建议几乎不做任何事情来验证此字段； IDN 意味着用户可以合法地在该字段中输入几乎所有内容:█▄ִ█▄█ִ▀ t.tk(当前是域名抢注者)或█ִ̲̲̲̅̅̅ b ִ̲̲̅̅ o ִ̲̲̅̅ x ִ̲̲̅̅ e ִ̲̲̅̅ d ִ̲̲̲̅̅̅█.tk(已对一些IDN域名进行分类的网站)或其他恐怖的合法地址，大多数浏览器都可以将其转换为幕后ASCII副本.

I recommend doing nearly nothing to validate this field; IDN means that users can legitimately enter nearly anything into the field: █▄ִ█▄█ִ▀▄▀.tk (currently a domain-squatter) or █ִ̲̲̲̅̅̅bִ̲̲̅̅oִ̲̲̅̅xִ̲̲̅̅eִ̲̲̅̅dִ̲̲̲̅̅̅█.tk (a website cataloging some IDN domain names) or other horrible-looking-yet legal addresses that most browsers can turn into their behind-the-scenes ASCII counterparts.
