目标是在浏览器中单击后退按钮时显示警报。它仅在单击“后退”按钮之前，单击页面上的其他位置时才起作用，否则它将转到上一页而没有警告消息，我已在此处包含我的代码。我想在页面加载后返回。
$(document).ready(function() {
if (window.history && window.history.pushState) {
//window.history.pushState('', null, './');
window.history.pushState(null, "", window.location.href);
$(window).on('popstate', function() {
alert('Warning! Your data will lose.');
document.location.href = 'www.redirecturl.com';
});
