我有一个MVC应用程序。完成网站后,我需要更改@url.content
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>

我认为你最好的选择就是创建另一个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提到的,我觉得你应该创建一个定制的html.image()帮助器,而不是试图覆盖url.content()帮助器,因为你的问题与图像有关,而不是url.content()本身。这是我如何处理这个问题:
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,上述内容纯粹是来自旧的mvc项目的“升力”,并添加了一条评论,以暗示您可能会做什么。我没有以任何方式对此进行测试,因此请注意:)
祝你好运
