Question

I would like to make an url rewriter in javascript, my problem is that if i make something like:

var str='/test/service-34.htm',
    exp='/test/service-[0-9]*.htm';
console.log(str.match(exp));

I would get ‘/test/service-34.htm’ as response, so if i can’t make a replace like:

/test/service-34.htm -> test.php?service=$1

Answer 1

Try:

"/test/service-34.htm".replace(
  /\/test\/service\-([0-9]+)\.htm/
, "test.php?service=$1"
);

It is important to create a backreference to use the [0-9] part in your replacement. Also you might want to use + instead of * to make the number required.
