用于匹配url中特殊字符的正则表达式模式

Question

I am trying to match url in javascript using match() function, It takes regex as a pattern. I need to match special characters of url ( ://..:/.?=& )

var url = 'http://www.sun.com:80/index.html?q=1&q2=2#fragment'; 

I have checked other pages but unable to find specific regex. and please also suggest good source to learn about writing regex.

[Update] I am trying to break url in strings save into the array like ( string= ['http', '', '', 'www', 'sun', 'com', '80', 'index', 'html', 'q', '1', 'q2', '2'] ) . For example - if pattern matches a variable saves the index position of url and then i use slice() function to extract the value ,my working url might be on different languages also (urdu etc) , i need to write regex for specific url symbols (:/.?=&# )

Answer 1

This is the simplest one (works for any language), since we added only the special characters here.

decodeURI(window.location.href).split(/[\/.?=&:#]+/g);

The following is for English:-

   var res = window.location.href.split(/[^A-Za-z0-9]+/g);

res will be the result array containing all text(param and values) except the special characters. There are better ways to parse the URL, but that depends on what is required. This solution is for what you exactly asked for. If URL contains Urdu characters:-

decodeURI(window.location.href).split(/[^A-Za-z0-9\u0600-\u06ff]+/g);

\؀-\\u6ff -> this is the unicode range of URDU characters. Now added that too. Note, we added "decodeURI", so that first the non-english characters will get decoded and then we do the search using regex.
