Question

I need to write regex in this code to detect id on url like this: http://example.com/#1

var url = "http://example.com/#1";
var id = ; // id naumber (any date after hash 0, 00, 0000...)
if (window.location.hash == "#" + id + "") {
 alert("your id is : " + id + "");
}

Answer 1

how about:

/#(\d+)/

the id is captured in group 1

var url = "http://example.com/#1";
var id = /#(\d+)/;
if (url.match(id)) {
     alert(url.match(id)[1]);
}
