[英]Asp.Net MVC - redirect to same page without passing parameter
I'm trying to redirect in same Index page that do multiple actions. 我正在尝试在同一索引页面中重定向以执行多项操作。
The problem is when in Index page with id parameter " http://example.com/Student/Index/1 " Url.Action("Index") or Html.ActionLink("Index") will always generate : " http://example.com/Student/Index/1 " instead of " http://example.com/Student " 问题是在ID参数为“ http://example.com/Student/Index/1 ”的索引页中,何时Url.Action(“ Index”)或Html.ActionLink(“ Index”)始终生成:“ http:/ /example.com/Student/Index/1 “代替” http://example.com/Student “
This happen on Menu and Breadcrumb. 这发生在菜单和面包屑上。
Controller : 控制器:
public ActionResult Index(int? id)
{
if (id == null) {
// Show List
} else if (id <= 0) {
// Show Create Form
} else {
//Show Edit Form
}
}
Is there any way to redirect to same page without parameter on View? 有没有办法在View上不带参数的情况下重定向到同一页面?
您可以将路由值设置为空字符串
@Html.ActionLink("Link text", "Index", new { id = "" })
There can be multiple ways. 可以有多种方式。 Action Link which generates the html link
生成HTML链接的Action Link
@Html.ActionLink("link text", "someaction", "somecontroller", new { id = "123" }, null)
generate as : 生成为:
<a href="/somecontroller/someaction/123">link text</a>
URL.action which only genrates url which you will need to put in html link tag URL.action仅生成您需要放入html链接标记中的url
Url.Action("someaction", "somecontroller", new { id = "123" })
generates 生成
/somecontroller/someaction/123
