我是否可以在任何地方看到当前Ajax.ActionLink方法的方法定义,因为我希望能够使用自定义方法扩展它但不确定其当前的方法定义
编辑:这是我到目前为止所做的:
public static class AjaxExtensions
{
public static IHtmlString MyActionLink(
this AjaxHelper htmlHelper,
string linkText,
string action,
string controller,
object routeValues,
AjaxOptions ajaxoptions,
object htmlAttributes
)
{
var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext);
var anchor = new TagBuilder("a");
anchor.InnerHtml = linkText;
anchor.Attributes["href"] = urlHelper.Action(action, controller, routeValues);
anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));
return MvcHtmlString.Create(anchor.ToString());
}
}
但显然我需要添加默认Ajax.ActionLink包含的AjaxOptions内容,但我不确定它的定义是什么样的。
这样做的原因是我希望linkText成为一个HtmlString,因为我想这样做:@Ajax.MyActionLink("<span class="highlight">Hello</span> World",...)
第二次编辑:
我现在收到编译错误:
...does not contain a definition for 'MyActionLink' and the best extension method overload 'MyProject.Helpers.AjaxExtensions.MyActionLink(System.Web.Mvc.AjaxHelper, System.Web.HtmlString, string, object, System.Web.Mvc.Ajax.AjaxOptions)' has some invalid arguments
这是我的扩展方法:
public static IHtmlString MyActionLink(
this AjaxHelper ajaxHelper,
HtmlString linkText,
string action,
object routeValues,
AjaxOptions ajaxoptions
)
{
return MyActionLink(ajaxHelper, linkText, action, routeValues, ajaxoptions);
}
以下是我如何使用它:
@Ajax.MyActionLink(@Html.Raw(item.ITEMID.Replace((string)ViewData["ID"], "<span class='highlighted'>" + (string)ViewData["ID"] + "</span>")), "MoreDetails", new { id = item.ITEMID }, new AjaxOptions()
{
UpdateTargetId = "MoreDetails-" + item.ITEMID,
InsertionMode = InsertionMode.Replace
})
第三次编辑:
我更改了我的扩展方法:
public static IHtmlString MyActionLink(
this AjaxHelper ajaxHelper,
IHtmlString linkText,
string action,
object routeValues,
AjaxOptions ajaxoptions
)
{
return MyActionLink(ajaxHelper, linkText, action, routeValues, ajaxoptions);
}
现在我收到以下错误:
Cannot evaluate expression because the current thread is in a stack overflow state. System.Collections.IDictionary
