如何把span元素在ActionLink MVC3
本文关键字:ActionLink MVC3 元素 span | 更新日期: 2023-09-27 18:18:00
我怎么能把一个span元素在ActionLink而不是与URL.ACTION?
:
<li><span>
@Ajax.ActionLink("LinkText", "ControllerName", new AjaxOptions
{
UpdateTargetId = "div",
InsertionMode = InsertionMode.Replace,
HttpMethod = "GET",
LoadingElementId = "progress"
})
</span></li>
生成:
<li>
<span>
<a href="/Home/ControllerName" data-ajax-update="#scroll"
data-ajax-mode="replace" data-ajax-method="GET"
data-ajax-loading="#progress" data-ajax="true">LinkText</a>
</span>
</li>
但是我需要别的东西。如何创建一个自定义的MVC3 ActionLink方法来生成以下输出:
<li>
<a href="/Home/ControllerName" data-ajax-update="#scroll"
data-ajax-mode="replace" data-ajax-method="GET"
data-ajax-loading="#progress" data-ajax="true">
<span>LinkText</span> // this span generated inside <a>
</a>
</li>
如何在ActionLink中放置span元素而不是URL。行动
简单的回答:你不能。ActionLink方法HTML对链接文本进行编码,对此你无能为力(你可以在微软开一个罚单,让他们提供一个重载,让你在ASP中完成这个操作)。. NET MVC vNext)。
现在你可以编写一个不编码的自定义html帮助器:
public static class AjaxExtensions
{
public static IHtmlString MyActionLink(
this AjaxHelper ajaxHelper,
string linkText,
string actionName,
AjaxOptions ajaxOptions
)
{
var targetUrl = UrlHelper.GenerateUrl(null, actionName, null, null, ajaxHelper.RouteCollection, ajaxHelper.ViewContext.RequestContext, true);
return MvcHtmlString.Create(ajaxHelper.GenerateLink(linkText, targetUrl, ajaxOptions ?? new AjaxOptions(), null));
}
private static string GenerateLink(
this AjaxHelper ajaxHelper,
string linkText,
string targetUrl,
AjaxOptions ajaxOptions,
IDictionary<string, object> htmlAttributes
)
{
var a = new TagBuilder("a")
{
InnerHtml = linkText
};
a.MergeAttributes<string, object>(htmlAttributes);
a.MergeAttribute("href", targetUrl);
a.MergeAttributes<string, object>(ajaxOptions.ToUnobtrusiveHtmlAttributes());
return a.ToString(TagRenderMode.Normal);
}
}
然后:
@Ajax.MyActionLink(
"<span>LinkText</span>",
"ActionName",
new AjaxOptions {
UpdateTargetId = "div",
InsertionMode = InsertionMode.Replace,
HttpMethod = "GET",
LoadingElementId = "progress"
}
)
我知道这是旧的,但我使用这种快速和肮脏的方式来添加样式按钮链接在我的网格。你可以添加重载来包含路由名等。也希望对大家有所帮助。
public static MvcHtmlString GridAnchor(this HtmlHelper html, string linkText, string actionName, string controllerName,
object routeValues, object htmlAttributes)
{
var result = new TagBuilder("a");
var url = UrlHelper.GenerateUrl(null, actionName, controllerName, new RouteValueDictionary(routeValues), html.RouteCollection,
html.ViewContext.RequestContext, true);
result.Attributes.Add("href", url);
result.MergeAttributes(new RouteValueDictionary(htmlAttributes));
result.InnerHtml = "<span>" + linkText + "</span>";
return MvcHtmlString.Create(result.ToString());
}
我稍微修改了Darins的答案,以便能够适应RouteValues。
<>之前
public static class AjaxExtensions
{
public static IHtmlString MyActionLink(
this AjaxHelper ajaxHelper,
string linkText,
string actionName,
AjaxOptions ajaxOptions
)
{
var targetUrl = UrlHelper.GenerateUrl(null, actionName, null, null, ajaxHelper.RouteCollection, ajaxHelper.ViewContext.RequestContext, true);
return MvcHtmlString.Create(ajaxHelper.GenerateLink(linkText, targetUrl, ajaxOptions ?? new AjaxOptions(), null));
}
public static IHtmlString MyActionLink(
this AjaxHelper ajaxHelper,
string linkText,
string actionName,
object routeValues,
AjaxOptions ajaxOptions
)
{
System.Web.Routing.RouteValueDictionary routeVals = new System.Web.Routing.RouteValueDictionary(routeValues);
var targetUrl = UrlHelper.GenerateUrl(null, actionName, null, routeVals, ajaxHelper.RouteCollection, ajaxHelper.ViewContext.RequestContext, true);
return MvcHtmlString.Create(ajaxHelper.GenerateLink(linkText, targetUrl, ajaxOptions ?? new AjaxOptions(), null));
}
private static string GenerateLink(
this AjaxHelper ajaxHelper,
string linkText,
string targetUrl,
AjaxOptions ajaxOptions,
IDictionary htmlAttributes
)
{
var a = new TagBuilder("a")
{
InnerHtml = linkText
};
a.MergeAttributes(htmlAttributes);
a.MergeAttribute("href", targetUrl);
a.MergeAttributes(ajaxOptions.ToUnobtrusiveHtmlAttributes());
return a.ToString(TagRenderMode.Normal);
}
}
我知道这是一个旧线程,但你也可以做一些内联的行:
<li><span>
@{
var lnk = Ajax.ActionLink("LinkText", "ControllerName", new AjaxOptions {
UpdateTargetId = "div",
InsertionMode = InsertionMode.Replace,
HttpMethod = "GET",
LoadingElementId = "progress"
});
@Html.Raw(lnk.ToString().Replace(">LinkText<", "><span>LinkText</span><"));
// Remember to include the open and closing >< !
}
</span></li>
我知道这是一个hack,但是你可以很容易地沿着这些行写一个扩展
使用JQuery实现这一点有多难?
我们总是可以使用JQuery
和附加<span></span>
一旦DOM加载。
可能不是完美的解决方案,但对于开发人员使用jquery和不想写html的帮助类如上答案,这可能是周围的工作
我使用Jetbrain的Annotation包修改了markdotnet的答案,以提供对actionName参数的智能感知。我还更改了linkText参数,以改善代码的可视化;VS会将其视为HTML代码,而不仅仅是一个简单的字符串。
的例子:
@Ajax.MyActionLink(
@<div>
<span>Click me</span>
</div>,
"MyAction",
new { Id = 1 },
new AjaxOptions
{
UpdateTargetId = "targed-id",
OnComplete = "oncomplete();"
})
