Javascript How can I extract the ID as INT from a URL?

I have url of the type:

localhost/Support/My-DNN-Module-Name/ID/133

I need to always extract the ID value at the end, in this case 133. This is what I am doing currently to extract it:

if (url) {
      // try tograb number as int from url
      var intValue = url.match( /\d+/ );
                if (intValue) {
                    console.log("converted url to int value and the result is: " + intValue);                   
                }
                else {
                    console.log("could not convert url to int value");
                }
}

Obviously this is not very good in case the URL contains other number(s), for example in the case that the localhost is entered as an actual ip address.

How can I target only the last part after ID and grab whatever number might be there please, ideally independent of what the url might look like before it?

Since the number you want always ends the string, you can add $ for the matched digits to be at the very end:

const str = 'localhost/12345/Support/My-DNN-Module-Name/ID/133';
const match = str.match(/\d+$/);
if (match) {
  console.log(match[0]);
}
