Trying To Match Url Pathname With Regex

I'm trying to match this: /Wedding to /Wedding/Areas /Wedding being the word to match. I think I'm not escaping the character correctly. var pattern = new RegExp('^/' + href + '*$

Solution 1:

var pattern = newRegExp("^/" + href + ".*$");

you forget the dot before the asterisk

but a better regex would be :

"^/" + href + "/.*$"

to be sure to have a subpath and not a partial word

Solution 2:

You can use the following regex to match the path name portion of a url:

var pathNameRegex = /^(?:(?:\w{3,5}:)?\/\/[^\/]+)?(?:\/|^)((?:[^#\.\/:?\n\r]+\/?)+(?=\?|#|$|\.|\/))/;


var matches = "https://stackoverflow.com/questions/9946435/trying-to-match-url-pathname-with-regex?rq=1".match(pathNameRegex);
//The last next of matches will have "questions/9946435/trying-to-match-url-pathname-with-regex"console.log(matches[matches.length - 1]);

   matches = "/questions/9946435/trying-to-match-url-pathname-with-regex?rq=1".match(pathNameRegex);
//The last next of matches will have "questions/9946435/trying-to-match-url-pathname-with-regex"console.log(matches[matches.length - 1]);

   matches = "//stackoverflow.com/questions/9946435/trying-to-match-url-pathname-with-regex?rq=1".match(pathNameRegex);
//The last next of matches will have "questions/9946435/trying-to-match-url-pathname-with-regex"console.log(matches[matches.length - 1]);
