Question

如何在单击链接时动态地将负margin-bottom应用于元素。单击时，尝试删除选项卡的下边框。当我对标签元素应用负边距时，它可以工作，但它适用于所有看起来很有趣的标签。有人可以看看吗？

jQuery(document).ready(function() {
    jQuery('.tabs .tab-links a').on('click', function(e)  {
        var currentAttrValue = jQuery(this).attr('href');
 
        // Show/Hide Tabs
        jQuery('.tabs ' + currentAttrValue).show().siblings().hide();
 
        // Change/remove current tab to active
        jQuery(this).parent('li').addClass('active').siblings().removeClass('active');
       // tried adding this code but it doesn't seem to work
        $(function() {
    		$('tab-links a').click(function () {
       			$( ".tab-links.active" ).css('margin-bottom','-2px');
    		});
		});

 
        e.preventDefault();

    });
});

Answer 1

尝试使用toggleClass，如下所示：

JS：

$( ".tab-links a" ).click(function() {
  $( this ).toggleClass( "neq-margin" );
});

CSS：

.neq-margin  {
  margin-bottom: -2px;
}

标签样式不适用
