如何在MVC中覆盖@url.content
本文关键字:覆盖 @url content MVC | 更新日期: 2023-09-27 18:22:48
我有一个MVC应用程序。完成网站后,我需要更改@url.content
的行为。
所以我需要在我的所有网站应用程序中覆盖@url.content
。我该怎么做?
<script src="@Url.Content("~/Scripts/jquery-1.7.1.js")"></script>
<script src="@Url.Content("~/Scripts/ui/jquery.ui.core.js")"></script>
<script src="@Url.Content("~/Scripts/ui/jquery.ui.widget.js")"></script>
<script src="@Url.Content("~/Scripts/ui/jquery.ui.tabs.js")"></script>
<script src="@Url.Content("~/Scripts/ui/jquery.ui.accordion.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.nivo.slider.js")"></script>
<script src="@Url.Content("~/Scripts/jwplayer.js")"></script>
我认为您最好只创建另一个UrlHelper
扩展方法。
public static class MyExtensions
{
public static string ContentExt(this UrlHelper urlHelper, string Content)
{
// your logic
}
}
MHF,
正如我在上面的评论中所提到的,我"觉得"你应该创建一个定制的html.image()帮助程序,而不是试图覆盖url.content()辅助程序,因为你的问题与图像有关,而不是url.content()本身
public static partial class HtmlHelperExtensions
{
public static MvcHtmlString Image(this HtmlHelper helper,
string url,
object htmlAttributes)
{
return Image(helper, url, null, htmlAttributes);
}
public static MvcHtmlString Image(this HtmlHelper helper,
string url,
string altText,
object htmlAttributes)
{
TagBuilder builder = new TagBuilder("image");
var path = url.Split('?');
string pathExtra = "";
// NB - you'd make your test for the existence of the image here
// and create it if it didn't exist, then return the path to
// the newly created image - for better or for worse!! :)
if (path.Length > 1)
{
pathExtra = "?" + path[1];
}
builder.Attributes.Add("src", VirtualPathUtility.ToAbsolute(path[0]) + pathExtra);
builder.Attributes.Add("alt", altText);
builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
return MvcHtmlString.Create(builder.ToString(TagRenderMode.SelfClosing));
}
}
用途:
@Html.Image("~/content/images/ajax-error.gif", new{@class="error_new"})
现在,上面的内容纯粹是从一个旧的mvc项目中"提升"出来的,添加了一条注释来提示你可能会做什么。我还没有以任何方式测试过这一点,所以请注意:)
祝好运
