You can do this with .replace():

您可以使用.replace()执行此操作:

var urlNumbers = $("#urlbox").val().replace("example.com/", "");

If you want to be safe and also remove any possible http:// or www. then use the following regex:

如果您想要安全并且还删除任何可能的http://或www。然后使用以下正则表达式:

var urlNumbers = $("#urlbox").val().replace(/example.com\/|http:\/\/|www./gi, "");

If your URL always looks like 'http:/example.com/123456' then you can just substring it at the last "/".

如果您的网址总是看起来像'http:/example.com/123456'那么您可以在最后一个“/”处对其进行子串。

In Javascript, you can detect the last "/" and split it like this:

在Javascript中,您可以检测到最后一个“/”并将其拆分为:

var originalUrl = $("#urlbox").val();
var urlNumbers = originalUrl.substring(originalUrl.lastIndexOf("/"));

However, it is better to do this on the PHP side (and work more securely with POST instead of GET):

但是,最好在PHP端执行此操作(并使用POST而不是GET更安全地工作):

$originalUrl = $_POST["short"];
$urlNumbers = substr($originalUrl, strrpos($originalUrl, "/"));
