URL을 찾아서 변수를 만드십시오.

Question

<p>Lorem ipsum dolor sit amet http://www.google.com/ consectetur adipisicing.</p> 

위 문장에서 URL에서 변수를 만드는 가장 좋은 방법은 무엇입니까?

jQuery가 문장을 검색하여 http으로 시작하는 항목을 찾고 공백 문자를 치기 전까지 변수와 그 다음에 나오는 모든 항목을 만들길 바랍니다. 따라서이 예에서 변수의 값은 http://www.google.com/입니다.

:contains과 정규식과 같은 무언가에 대해 생각하고 있었습니까?

그래서 :

var url = $("p").html().match(/that whole thing/); 

What is the best regular expression to check if a string is a valid URL?

그것은 아무튼
