jQuery实现页面点击后退弹出提示框的方法

jQuery(document).ready(function ($) {
  if (window.history && window.history.pushState) {
    $(window).on('popstate', function () {
      var hashLocation = location.hash;
      var hashSplit = hashLocation.split("#!/");
      var hashName = hashSplit[1];
      if (hashName !== '') {
        var hash = window.location.hash;
        if (hash === '') {
          alert("希望该网站能提供你帮助！");
        }
      }
    });
    window.history.pushState('forward', null, './#forward');
  }
});
