problems

问题

  1. there is a possibly test.for we cant use good regex like /[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}/gi i think its best for using something like below better
  2. 有一个可能的测试。我们不能用很好的正则表达式/(a-z0-9)+((\ \]{ 1 }[a-z0-9]+)* \。[a-z]{2,5}/gi我认为使用下面这样的东西最好
  3. maybe i found a solution;
  4. 也许我找到了解决办法;

found = string.match(/([a-zA-Z0-9]+\.(com|co\.cc)|more\.domains)/gi);

发现= string.match(/((a-zA-Z0-9)+ \。(com |有限公司\ .cc)|更多\ .domains)/ gi);

this work great, i have a problem to join/replace them to the original string. any workarounds like how can we filter elements in array with regex in array with javascript?

这工作很好，我有一个问题连接/替换它们到原始字符串。任何解决方法，比如我们如何使用javascript在数组中使用regex过滤数组中的元素?

how would you tackle this problem? btw im using nodejs other language is acceptable.

你将如何解决这个问题?顺便说一句，我使用nodejs其他语言是可以接受的。

thanks

This handles www.example.com correctly:

这个处理www.example.com正确:

tld = ["com", "org", "edu", "net"] // feel free to add more

var input = "this is a test.for a question. at www.*.com " 
    + "the best place to learn. "
    + "programming.test wikipedia.com and windows.microsoft.edu";


re = new RegExp('\\S+\\.(' + tld.join('|') + ')\\b', 'g')

var dotted = input.replace(re, function($0) {
    return $0.replace(/\./g, "[dot]");
});

// this is a test.for a question. at www[dot]*[dot]com the best place to learn. 
// programming.test wikipedia[dot]com and windows[dot]microsoft[dot]edu
