I want to get the relative URL from an absolute URL in JavaScript using regex and the replace method.

I tried the following but it is not working:

var str="http://localhost/mypage.jsp";
document.write(str.replace("^[\w]*\/\/[\w]*$",""));

    If by “relative URL” you mean the part of the string after the first single /, then it’s simple:

    document.write(str.replace(/^(?:\/\/|[^/]+)*\//, ''));

    This matches all the characters up to the first single / in the string and replaces them with the empty string.

    In: http://localhost/my/page.jsp –> Out: /my/page.jsp
