我发现了这个 JS FIDDLE ,它可以通过全宽下拉来完成我需要的工作。
问题:
我试图将按钮准确地放在中间,并以此填充宽度下拉菜单为中心。出于某种原因,当我使用html <center>
标签时,它不起作用。
$(document).ready(function() {
//variable where currentAnchor is stored
var currentSection = 0;
// hides the submenu as soon as the DOM is ready
$('#submenu').hide();
// toggles the submenu on clicking the noted link
$('#menu li a').click(function() {
// remove active class
$('#menu li a').removeClass('active');
// add active class
$(this).addClass('active');
var href = $(this).attr('href');
//hide all submenus
$('#hidden>ul').hide();
//show one particular menu
$(href).show();
//logic for hiding and showing submenu
if(currentSection == 0){
$('#submenu').slideToggle(200);
currentSection = href;
} else if(currentSection == href){
$('#submenu').slideToggle(200);
currentSection = 0;
} else{
currentSection = href;
}
return false;
});
});
#menu li {
display: inline-block;
}
#menu li a {
padding: 10px 20px;
background: #e45740;

你必须写下面的css来制作中心的按钮
#menu{
margin: 0 auto;
display: table;
}
我希望它有效......

假设您的HTML结构与提供的小提琴链接相同,您只需要将text-align:center;
添加到您的ul中,如下所示:
#menu {
text-align: center;
}
