Don't. The browser does that for you. Simply have a name="contact" attribute and the browser will scroll down to that element automatically. for instance:

<h2 name="contact">The contact form is below</h2>
<form> ...

You can use this simple code to get the URL hash.

var hash = window.location.hash;
if(hash == "#contact") {
    // code
}

Note: this will also return the "#" tag!

url.match(/#contact$/) should return the matches as an array. Just check if it's not null.

The hash in the URL will map to the node with the same ID value. So in your case the page will auto scroll to div with an idea of #contact

you can use

var urlName = document.location.href;
var hash = urlName.split("#").length;
