在click / ul li / jQuery上顺利滚动

标签： javascript jquery scroll

我遇到了问题＆＃34; Q＆amp; A＆＃34;部分。就像那里有4个问题，那就是链接。 如果你点击一个，那么＆＃34; p＆＃34;将会滑下来。等等。但是当我点击这个问题时，我希望页面向下或向上滚动（如顶部）。

$(function() {
  var $_openedFaq = null;


  function openFaq($__p) {
    $__p.slideDown();
  }


  function closeFaq($__p) {

  }


  $('.faq ul li').each(function() {
    var $faq = $(this);
    var $p = $(this).find('p');


    $(this).find('a').click(function(e) {
      e.preventDefault();

      if ($_openedFaq != null) {
        closeFaq($_openedFaq.find('p'));

        $_openedFaq.find('a').removeClass("open");
      }


      if (($_openedFaq == null) || (($_openedFaq != null) && !$faq.is($_openedFaq))) {
        openFaq($p);

        $_openedFaq = $faq;

所以当你点击＆＃34;问题1＆＃34;我希望页面滚动，直到她与问题1相提并论。对不起我糟糕的英语^^

谢谢。

答案 0 :(得分：0)

$(document).on('click', 'a[href^="#"]', function    (     (event) {
event.preventDefault();

$('html, body').animate({
    scrollTop: $($.attr(this, 'href')).offset().top
}, 500);

}）;

href是目标

的ID

答案 1 :(得分：-1)

您可以通过以下方式收集每个元素li的偏移顶部：

var offset = $(this).offset().top;

然后顺利滚动使用：

$('html, body').animate({
     scrollTop: offset
}, 1000);

<强>演示：

＆＃13;
＆＃13; 
$(function() {
  var $_openedFaq = null;


  function openFaq($__p) {
    $__p.slideDown();
  }


  function closeFaq($__p) {
    $__p.slideUp();
  }


  $('.faq ul li').each(function() {
    var $faq = $(this);
    var $p = $(this).find('p');
    var offset = $(this).offset().top;

    $(this).find('a').click(function(e) {
      e.preventDefault();
      
 $('html, body').animate({
        scrollTop: offset
    }, 1000);
      
      if ($_openedFaq != null) {
        closeFaq($_openedFaq.find('p'));

        $_openedFaq.find('a').removeClass("open");
      }


      if (($_openedFaq == null) || (($_openedFaq != null) && !$faq.is($_openedFaq))) {
        openFaq($p);

        $_openedFaq = $faq;

        $p.prev('a').addClass("open");

      } else {
        $_openedFaq = null;
      }
    });
  });
