Question

从元素上移出鼠标时，我首先要激活它。

我正在尝试隐藏当前元素：$(this).find('a').tab('hide'); 但这没有效果。

$('.nav-tabs > li').mouseover( function(){
  $(this).find('a').tab('show');
});

$('.nav-tabs > li').mouseout( function(){
  $(this).find('a').tab('hide');
});

Answer 1

找到第一个标签，然后使用标签将其选中。

$('.nav-tabs > li').mouseover( function(){
  $(this).find('a').tab('show');
});
$('.nav-tabs > li').mouseout( function(){
  $('a[href="#tab1"]').tab('show');
});

使用jquery时，您可以通过以下方式隐藏标签页：获取标签页引用并在删除鼠标时隐藏。

请遵循以下示例。

$('.nav-tabs > li').mouseover( function(){
    $('a', this).tab('show');
});
$('.nav-tabs > li').mouseout( function(){
    $(this).removeClass('active');

    const tab = $('a', this).attr('href');
    $(tab).removeClass('active');
});
