This article will explain in detail what are the regular expressions for matching URLs. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.

A regular expression describes a pattern of string matching, which can be used to check whether a string contains a certain substring, replace a matching substring, or extract a substring from a string that meets a certain condition.

Then the expression:

var match = /^((ht|f)tps?):\/\/ [\w\-]+(\. [\w\-]+)+([\w\-\.,@?^=%&:\/~\+#]* [\w\-\@?^=%&\/~\+#])?$/;

Match:

(1), directly match domain name address:

var matchString = 'https://i.cnblogs.com/';console.log(match.test(matchString)); // ==> true

(2), matching links containing (*.htm,*.html,*.php,*.aspx...) Address of suffix:

var matchString = 'https://i.cnblogs.com/EditPosts.aspx';console.log(match.test(matchString)); // ==> true

(3), matching address with parameters:

var matchString = 'https://i.cnblogs.com/EditPosts.aspx? opt=1';console.log(match.test(matchString)); // ==> true

Instructions for use:

(1)The address must start with http/https/ftp/ftps;

(2)Address cannot contain two-byte symbols or non-linked special characters.
