Bootstrap 3.x: how to have url change upon clicking modal trigger?

Question

Using Bootstrap v3.3.5

I have a webpage that is using the url domain.com/companies

This is my trigger for the modal in that webpage.

<a href="#modal-add-company" class="btn btn-effect-ripple btn-effect-ripple btn-success" data-toggle="modal"><i class="fa fa-plus"></i> New Company</a>

This will successfully trigger this modal

<div id="modal-add-company" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true">

However, the url does not change to domain.com/companies#modal-add-company

Nor does the url domain.com/companies#modal-add-company actually trigger the modal on reload.

What do I need to do to have the following:

1. change the url to domain.com/companies#modal-add-company whenever I trigger the modal and the modal is shown, and
2. if i directly type the url domain.com/companies#modal-add-company, the modal is shown

Using jQuery this could be a viable solution

$(document).ready(function(){
   $(window.location.hash).modal('show');
   $('a[data-toggle="modal"]').click(function(){
      window.location.hash = $(this).attr('href');
   });
});

Assuming you have a trigger to close the modal like this:

<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>

You can add this below the code block above:

$('button[data-dismiss="modal"]').click(function(){
     var original = window.location.href.substr(0, window.location.href.indexOf('#'))
     history.replaceState({}, document.title, original);
 });

And assuming you want escape button to still be able to close the modal, and also change the url the whole code block would look like this:

    $(window.location.hash).modal('show');
    $('a[data-toggle="modal"]').click(function(){
        window.location.hash = $(this).attr('href');
    });

    function revertToOriginalURL() {
        var original = window.location.href.substr(0, window.location.href.indexOf('#'))
        history.replaceState({}, document.title, original);
    }

    $('.modal').on('hidden.bs.modal', function () {
        revertToOriginalURL();
    });
