如何在单击链接时动态地将负 margin-bottom 应用于元素。尝试在单击选项卡时删除选项卡的底部边框。当我对 tab 元素应用负边距时，它起作用了，但它应用于所有看起来很有趣的选项卡。有人可以看一下吗？
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();
});
});/*----- Tabs -----*/
.tabs {
width:100%;
display:inline-block;

/* Clearfix */
.tab-links:after {
display:block;
clear:both;
content:'';
margin-bottom: -18px;

尝试像这样使用 toggleClass:
JS:
$( ".tab-links a" ).click(function() {
$( this ).toggleClass( "neq-margin" );
});
CSS:
.neq-margin {
margin-bottom: -2px;
}
