我有一个菜单栏。我刚刚找到一些有用的东西，使整个菜单栏区域可以用jquery点击。
这是设计代码：
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MenuControl.ascx.cs" Inherits="MenuControl"%>
<link rel="stylesheet" href="css/Menu3.css" type="text/css" />
<div id="header" align="center" >
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$(".Menu").click(function(e) {
window.location = $(e.target).find("a").attr("href");
return false;
});
});
</script>
<table width="100%" cellpadding ="0" cellspacing ="0" align="center">
<tr>
<td align="center">
<asp:Menu ID="Menu1" runat="server" Orientation ="Horizontal" CssClass="Menu"
ForeColor ="Black" Width="100%" ScrollDownText=""
StaticPopOutImageUrl="~/images/down_arrow_1.gif">
<StaticMenuItemStyle Height="40px"/>
<DynamicMenuItemStyle Height="40px" CssClass="Menu" HorizontalPadding="10px"/>
<StaticHoverStyle CssClass="menuhover" />
<DynamicHoverStyle CssClass="menuhover" />
</asp:Menu>
</td>
</tr>
</table>
</div>
当我点击菜单项的区域但是当我点击原始菜单项时，如何正常工作，那么错误就像：
Server Error in '/EasyWeb' Application.

答案 0 :(得分：1)
你的问题在这里：
window.location = $(e.target).find("a").attr("href");
当您点击a元素时，e.target会成为a元素本身，所以......
$(e.target).find('a');
返回一个空的jQuery对象，因为e.target没有子元素。如果你想使用e.target：
var $a = e.target.nodeName.toLowerCase() == 'a' ? $(e.target) : $(e.target).find('a');
window.location = $a.attr('href');
通过这种方式，您可以检查是否已经点击了a元素。如果是的话，使用它;如果没有，搜索它。
