好的,所以我有一个我想要制作的网站,并且有一个应该有效的下拉菜单。我甚至已经在这里使用了其中一个答案来获取此菜单的代码,创建了所有适当的类和所有内容,但它仍然拒绝工作。就此而言,我的意思是它只是静静地坐在那里。它应该从图像中下拉。

你需要添加jQuery,否则这将无效。

尝试使用preventdefault和stopimmediatepropagation:
$(function () {
$(".hoverli").hover(
function() {
$('ul.file_menu').slideDown('medium');
},
function() {
event.preventDefault();
$('ul.file_menu').slideUp('medium');
}
);
$(".file_menu li").hover(
function() {
event.preventDefault();
event.stopImmediatePropagation();
$(this).children("ul").slideDown('medium');
},
function() {
event.preventDefault();
event.stopImmediatePropagation();
$(this).children("ul").slideUp('medium');
}
);
});
