我在ASP.net菜单中为具有子下拉菜单的菜单项设置了弹出图像。问题是我希望能够在悬停时更改图像,并且不确定我是否可以通过CSS或C#来完成。
带箭头图片的菜单项:
ASPX代码:
<asp:Menu ID="Menu1" StaticPopOutImageUrl="~/Sites/0/PageLayouts/Images/Horizontal_Main_Arrow.jpg" ItemWrap="false" runat="server" Orientation="Horizontal">
<DataBindings>
<asp:MenuItemBinding DataMember="MenuItem" TextField="Title" NavigateUrlField="URL" />
</DataBindings>
<StaticMenuStyle CssClass="TopStaticMenuStyle" />
<StaticSelectedStyle CssClass="TopStaticSelectedStyle" />
<StaticMenuItemStyle CssClass="TopStaticMenuItemStyle" />
<DynamicHoverStyle CssClass="TopDynamicHoverStyle" />
<DynamicMenuStyle CssClass="TopDynamicMenuStyle" />
<DynamicSelectedStyle CssClass="TopDynamicSelectedStyle" />
<DynamicMenuItemStyle CssClass="TopDynamicMenuItemStyle" />
<StaticHoverStyle CssClass="TopStaticHoverStyle" />
页面来源:
<td onmouseover="Menu_HoverStatic(this)"
onmouseout="Menu_Unhover(this)"
onkeyup="Menu_Key(event)"
id="ctl00_ContentPlaceHolder1_ctl00_ctl00_ctl00_Menu1n1">
<table class="TopStaticMenuItemStyle ctl00_ContentPlaceHolder1_ctl00_ctl00_ctl00_Menu1_4"
cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td style="white-space:nowrap;">
<a class="ctl00_ContentPlaceHolder1_ctl00_ctl00_ctl00_Menu1_1 TopStaticMenuItemStyle ctl00_ContentPlaceHolder1_ctl00_ctl00_ctl00_Menu1_3"
href="Home.aspx" target="_self"
style="border-style:none;font-size:1em;"
>Our Expertise</a>
</td>
<td style="width:0;">
<img src="../Sites/0/PageLayouts/Images/Horizontal_Main_Arrow.jpg"
alt="Expand Our Expertise"
style="border-style:none;vertical-align:middle;" />
</td>
</tr>
</table>
</td>

您可以使用Javascript执行此操作 - 只需将以下属性添加到您的img标记:
的onmouseover = “this.src = '.. /站点/ 0 /页面布局/图像/ Horizontal_Main_Arrow_Highlighted.jpg';”
的onmouseout = “this.src = '.. /站点/ 0 /页面布局/图像/ Horizontal_Main_Arrow.jpg';”
(或者你的其他jpg是什么!)
