当鼠标移回处理程序元素时，防止滑动事件

Question

当用户将光标移回处理程序元素时，我想阻止/停止滑动功能。

例如，如果您将鼠标悬停在Home上，.tab-pane将向下滑动，如果您将鼠标从.tab-pane移至Home标签，则会重新向下滑动内容。我需要检测鼠标是否来自关联的.tab-pane什么都不做。

$('a[data-toggle="tab"]').hover(
  function(e) {
    $(this).parent().addClass('active');
    var target = $(this).data("target");
    $($(e.target).attr('href')).slideDown('slow');
  },
  function(e) {
    $(this).parent().removeClass('active');
    var target = $(this).data("target");

    var targetId = target.replace('#', '');
    var relatedTarget = $(e.relatedTarget);

    if (relatedTarget.attr('id') === targetId) {
      return;
    }

    $($(e.target).attr('href')).hide();
  }
);

$('.tab-pane').hover(function(e) {}, function() {
  $(this).slideUp('slow');
  $('.nav-tabs li').removeClass('active');
});

.tab-pane {
  border-left: 1px solid #eee;
  border-right: 1px solid #eee;
  border-bottom: 1px solid #eee;
  padding: 20px;
  background: #ddd;
}

我只调整了脚本，请试试这个：

＆＃13;

＆＃13;

$('a[data-toggle="tab"]').hover(
  function(e) {
    $(this).parent().addClass('active');
    var target = $(this).data("target");
    $('.tab-pane.active:not(#'+target+')').hide(); // Hide the tab panel except the current target
    $($(e.target).attr('href')).slideDown('slow').addClass('active'); // Add the class 'active' to the tab panel
  },
  function(e) {
    $(this).parent().removeClass('active');
    var target = $(this).data("target");

    var targetId = target.replace('#', '');
    var relatedTarget = $(e.relatedTarget);

    if (relatedTarget.attr('id') === targetId) {
      return;
    }

    $($(e.target).attr('href')).hide();
  }
);
$('.container').hover(
  function(e) {},
  function(e) {
    $('.tab-pane.active').slideUp('slow');
    $('.nav-tabs li').removeClass('active');
});

＆＃13;

.tab-pane {
  border-left: 1px solid #eee;
  border-right: 1px solid #eee;
  border-bottom: 1px solid #eee;
  padding: 20px;
  background: #ddd;
}
