我在 anchor 标记内有一个按钮，当我单击该按钮时，我希望它平滑地滚动到具有 id“bodycontainer”的 div。

我认为问题出在 javascript 上，有什么想法吗？

$(function(){
  $('.icon-menu').click(function() {
    $('.menu').animate({
      left: "0px"
    }, 200);

    $('body').animate({
      left: "285px"
    }, 200);
  });

  $('.icon-close').click(function() {
    $('.menu').animate({
      left: "-285px"
    }, 200);

    $('body').animate({
      left: "0px"
    }, 200);
  });
  
  $('#bodycontainer').click(function() {
    var target = $(this.hash);
    target = target.length ? target : $('[name=' + this.hash.substr(1) +']');
    if (target.length) {
      $('html,body').animate({
        scrollTop: target.offset().top
      }, 1000);
      return false;
    }
  });
});
body {
  font-family: 'Nunito', sans-serif;
  padding: 0;
  margin: 0;
  display: block;
}

  margin: 0;

window.jQuery

最佳答案

太复杂了，JS应该是这样的

$('#start').click(function() {
    $('html,body').animate({
        scrollTop: $('#bodycontainer').position().top
    }, 1000 );

});
