我已经为菜单栏转储了bootstrap3。
它工作正常，点击主菜单显示子菜单项。
但我想要的是，应在hover主菜单子菜单项上显示。
以下是onclick工作菜单栏的代码：
<div class="jumbotron">
<div class="container">
<p class="lead">Grid Example</p>

Javascript如下：
<script>
$(function() {
window.prettyPrint && prettyPrint()
$(document).on('click', '.yamm .dropdown-menu', function(e) {
e.stopPropagation()
})
})
</script>
任何人都可以帮我解决这个问题。 提前谢谢。
答案 0 :(得分：0)
试试这个：
<script>
$("#nav li").hover(
function(){
$(this).children('ul').hide();
$(this).children('ul').slideDown('slow');
},
function () {
$('ul', this).slideUp('slow');
});
</script>
并使你像这样
<ul id="nav">
