Hitting POST routes with link.

So I'm looking for some advice on whether this is a good idea or not. I have come across a few situation when building apps where I want to trigger a route via a link, but I want want to use a something other than a GET request. A good example of this would be logging a user out. I could do this with a GET, but I would prefer to use POST or DELETE as to avoid any chance the user could bookmark the link. So I came up with a solution. I created a small javascript function.

function sendAsPost(action)
{
    var form = $('#sendAsPostForm');
    form.attr('action', action);
    form.submit();
}

Then I add a form to my main layout so it's on every page.

<form action="" method="POST" id="sendAsPostForm">
    {!! csrf_field() !!}
</form>

Now I can call a POST route with a link from anywhere in my app as simple as this:

<a href="#" onclick="sendAsPost(' route('logout') ')">Log-out</a>

--for some reason it removes the blade syntax curly braces around the route--

This seems to work great, I was just wondering how other people have dealt with this? Or if this is a terrible idea for some reason I'm not seeing. Thanks!
