You can't refresh without the warning; refresh instructs the browser to repeat the last action. It is up to the browser to choose whether to warn the user if repeating the last action involves resubmitting data.

You could re-navigate to the same page with a fresh session by doing:

<pre><code>window.location = window.location.href;
</code></pre>

I've written a function that will reload the page without post submission and it will work with hashes, too. 

I do this by adding / modifying a GET parameter in the URL called <code>reload</code> by updating its value with the current timestamp in ms. 

<pre><code>var reload = function () {
 var regex = new RegExp("([?;&amp;])reload[^&amp;;]*[;&amp;]?");
 var query = window.location.href.split('#')[0].replace(regex, "$1").replace(/&amp;$/, '');
 window.location.href =
 (window.location.href.indexOf('?') &lt; 0 ? "?" : query + (query.slice(-1) != "?" ? "&amp;" : ""))
 + "reload=" + new Date().getTime() + window.location.hash;
};
</code></pre>

Keep in mind, if you want to trigger this function in a href attribute, implement it this way: <code>href="javascript:reload();void 0;"</code> to make it work, successfully.

The downside of my solution is it will change the URL, so this "reload" is not a real reload, instead it's a load with a different query. Still, it could fit your needs like it does for me.

The other solutions with <code>window.location</code> didn't work for me since they didn't make it refresh at all, so what I did was that I used an empty form to pass new and empty postdata to the same page. This is a way to do that based on <a href="https://stackoverflow.com/a/43482781/4284627">this answer</a>:

<pre><code>function refreshAndClearPost() {
 var form = document.createElement("form");
 form.method = "POST";
 form.action = location.href;
 form.style.display = "none";

 document.body.appendChild(form);
 form.submit(); //since the form is empty, it will pass empty postdata
 document.body.removeChild(form);
}
