javascript - 如何使用 jquery 使整个菜单栏元素+区域可点击

Question

我有一个菜单栏。我刚刚发现了一些有用的东西，使整个菜单栏区域应该可以用 jquery 点击。

这里是设计代码:

<%@ 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>

当我单击菜单项的区域时如何工作正常但是当我单击原始菜单项时会发生如下错误:

Server Error in '/EasyWeb' Application.

我的 jquery 代码有问题吗？？

Answer 1

你的问题在这里:

window.location = $(e.target).find("a").attr("href");

当您单击 a 元素时，e.target 将成为 a 元素本身，因此...

$(e.target).find('a');

返回一个空的 jQuery 对象，因为 e.target 没有子元素。如果您想使用 e.target，您需要这样做:

var $a = e.target.nodeName.toLowerCase() == 'a' ? $(e.target) : $(e.target).find('a');
window.location = $a.attr('href');

这样您就可以检查您是否已经点击了 a 元素。如果是，则使用它；如果没有，搜索它。
