javascript - 平滑滚动前的 sleep 功能

Question

如何在平滑滚动之前添加 3 秒暂停？用户点击按钮，然后会休眠 3 秒，然后平滑滚动就会运行。

 $(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

您可以像这样添加 setTimeout() :

 $(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        setTimeout(function(){
          $('html,body').animate({
            scrollTop: target.offset().top
          }, 1000);
        }, 3000);
        return false;
      }
    }
  });
});
