I have an MVC application. After I finished the web site I need to change @url.content
behavior.
So I need to override @url.content
in all of my website application. How can I do it?
<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>
I think your best bet here would be just to create another UrlHelper
Extension Method.
public static class MyExtensions
{
public static string ContentExt(this UrlHelper urlHelper, string Content)
{
// your logic
}
}
MHF,
As mentioned in my comments above, i 'feel' you should create a bespoke html.image() helper, rather than try to override the url.content() helper, given that your problem is related to images, and not url.content() per se. here's how i'd approach this:
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));
}
}
useage:
@Html.Image("~/content/images/ajax-error.gif", new{@class="error_new"})
Now, the above is purely a 'lift' from an old mvc project, with a comment added to give a hint as to what you might do. I haven't tested this in any way, so caveat emptor :)
good luck
