onclick is deprecated and hard to read. Consider to use a listener to your button!

The code to refresh a page is window.location.reload();

    let btn_01;
    document.addEventListener("DOMContentLoaded", onReady);
    function onReady(){
        btn_01 = document.getElementById("button_1");
        btn_01.addEventListener("click",click_1);
    }
    function click_1(){
        window.location.reload();
    }

.button {
  background-color: #4CAF50; /* Green */
  border: none;
  color: white;
  padding: 8px 8px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 16px;
  margin: 4px 2px;
  cursor: pointer;
}

.button2 {background-color: #008CBA;} /* Blue */

<button id="button_1" >Refresh</button>

CodePudding user response：

you must change 2 things:

atribute onclick: you mus have this: " around the javascript. like

<button onclick="location=URL" >Refresh</button>

if you like to use style with .button, you must add atribute . like this:

<button onclick="location=URL"  >Refresh</button>

or, you can use other think in style: instead of .button{ ... }, use button{ ... }.

CodePudding user response：

I can't see how you are using the onclick. but something is wrong here:

<button onclick=location=URL>Refresh</button>

Parenthesis are missing. Maybe try something along the line of this

<button onclick="location.href='../'">
