잘못된 트리거를 피하면서 웹 브라우저에서 뒤로 버튼 클릭을 정확하게 감지하는 방법은 무엇입니까?

<code class="js">window.onload = function () {
  if (typeof history.pushState === "function") {
    history.pushState("jibberish", null, null);
    window.onpopstate = function () {
      history.pushState('newjibberish', null, null);
      // Handle back or forward button clicks here (excluding refresh)
    };
  } else {
    ... // Handle non-History API browsers
  }
}</code>

<code class="js">window.onload = function () {
  ... // Similar to History API code
} else {
  var ignoreHashChange = true;
  window.onhashchange = function () {
    if (!ignoreHashChange) {
      ignoreHashChange = true;
      window.location.hash = Math.random();
      // Detect back button click here
      // Note: Messes with hash symbol at the end of URL
    } else {
      ignoreHashChange = false;
    }
  };
}</code>

<code class="js">window.onbeforeunload = function (e) {
  if (e.preventDefault) {
    e.preventDefault();
    e.returnValue = '';
  }
}</code>
