我有这个代码。我在按钮单击时应用了隐藏/显示功能。它工作得很好，但只显示子列表的第一个值。不知道什么破了。有人能帮我吗？
<div ><button id="showmenu" type="button">Show menu</button></div>
<div class="sidebarmenu" style="display: none;">
<ul id="sidebarmenu1">
<li><a href="#" >Circle List</a>
<ul>
<li><a href="addCircle.jsp">Add</a></li>
<li><a href="EditDiv.jsp">Edit</a></li>
<li><a href="deletediv.jsp">Delete</a></li>
<li><a href="adddivision.jsp">View All</a></li>
</ul>
</li>
</ul>
</div>
</div>
这是我的 jQuery
$(document).ready(function() {
$('#showmenu').click(function() {
$('#showmenu').text($('.sidebarmenu').is(':visible') ? 'Show Menu' : 'Hide Menu');
$('.sidebarmenu').toggle("slide");
});
});
这是我的 CSS
.sidebarmenu ul {
margin: 0;
padding: 0;
list-style-type: none;
font: bold 12px verdana;
width: 180px; /* Main Menu Item widths */
border-bottom: 1px solid #ccc;
}
.sidebarmenu ul li {
position: relative;
}
/* Top level menu links style */
.sidebarmenu ul li a {
display: block;
overflow: auto; /*force hasLayout in IE7 */
color: black;
text-decoration: none;
padding: 6px;
border-top: 1px solid #bbb;
border-bottom: 1px solid #bbb;
border-right: 1px solid #bbb;
}
.sidebarmenu ul li a:link,.sidebarmenu ul li a:visited,.sidebarmenu ul li a:active
{
background-color: #d2d2d2 /*background of tabs (default state)*/
}
.sidebarmenu ul li a:visited {
color: black;
}
.sidebarmenu ul li a:hover {
background-color: #e8e8e8;
}
/*Sub level menu items */
.sidebarmenu ul li ul {
position: absolute;
width: 89px; /*Sub Menu Items width */
top: 0;
visibility: hidden;
}
.sidebarmenu a.subfolderstyle{
background: url(../images/right.PNG) no-repeat 97% 50%;
}
/* Holly Hack for IE \*/
* html .sidebarmenu ul li {
float: left;
height: 1%;
}
* html .sidebarmenu ul li a {
height: 1%;
}
这是我的 JS：
<script type="text/javascript">
//Nested Side Bar Menu (Mar 20th, 09)
//By Dynamic Drive: http://www.dynamicdrive.com/style/
var menuids = [ "sidebarmenu1" ] //Enter id(s) of each Side Bar Menu's main UL, separated by commas
function initsidebarmenu() {
for ( var i = 0; i < menuids.length; i++) {
var ultags = document.getElementById(menuids[i])
.getElementsByTagName("ul")
for ( var t = 0; t < ultags.length; t++) {
ultags[t].parentNode.getElementsByTagName("a")[0].className += " subfolderstyle"
if (ultags[t].parentNode.parentNode.id == menuids[i]) //if this is a first level submenu
ultags[t].style.left = ultags[t].parentNode.offsetWidth
+ "px" //dynamically position first level submenus to be width of main menu item
else
//else if this is a sub level submenu (ul)
ultags[t].style.left = ultags[t - 1]
.getElementsByTagName("a")[0].offsetWidth
+ "px" //position menu to the right of menu item that activated it
ultags[t].parentNode.onmouseover = function() {
this.getElementsByTagName("ul")[0].style.display = "block"
}
ultags[t].parentNode.onmouseout = function() {
this.getElementsByTagName("ul")[0].style.display = "none"
}
}
for ( var t = ultags.length - 1; t > -1; t--) { //loop through all sub menus again, and use "display:none" to hide menus (to prevent possible page scrollbars
ultags[t].style.visibility = "visible"
ultags[t].style.display = "none"
}
}
}
if (window.addEventListener)
window.addEventListener("load", initsidebarmenu, false)
else if (window.attachEvent)
window.attachEvent("onload", initsidebarmenu)
</script>
注意：我只发布了 HTML 的一部分。我的列表中有更多项目，当没有应用幻灯片功能时，完整的子列表看起来很好。
