带有帖子功能的MVC Html.ActionLink？

Question

I'm checking to see if anyone has written an MVC extension for Html.ActionLink that you can pass in Post parameters like such:

<% Html.ActionLink("Click me", "Index", "Home", new { MyRouteValue = "123" }, null, new { postParam1 = "a", postParam2 = "b" }); %>

That would render the link like normal but having an onClick event that submits an also rendered form with an Action url for the Action, Controller, and Route Values with additional hidden inputs from the Post Parameters like such:

<a href="#" onClick="$('#theform').submit(); return false;">Click me</a>
<form id="theform" action="/Home/Index/123" method="post">
   <input type="hidden" name="postParam1" value="a">
   <input type="hidden" name="postParam2" value="b">
</form>

I'm looking to redirect users to various pages with potentially a lot of data. Not only from page to page, but from email to page also. This would be highly reusable and I think would clean up a lot of code, and would save a bunch of time writing this if its already floating around out there. I hate recreating the wheel when I don't have to.

Answer 1

ActionLink is just for creating an <a> . What you are asking for would blow up if it is already inside of a form. If it isn't then it is preferable to make the link the submit button inside the form and NOT use javascript (javascript and emails don't get along great).

You could create the form and appende it to the end of the DOM. This could be done through partial view or through javascript.

Honestly I suggest you don't use a POST. If you persist most of the data and just have the ids needed to retrieve said data, you should never have to pass too much data in an actionlink.

Ajax.ActionLink works perfectly fine for a post request. To refresh page, you can create a function that refreshes page (eg function reload(){ windows.location.reload();} ). It would look something like this.

@Ajax.ActionLink("DiaplyName", "Action", new { parameters to post }, new AjaxOptions { HttpMethod = "POST", InsertionMode = InsertionMode.Replace, OnComplete="reload();"})

Note: You'll need to reference the appropriate scripts to use ajax or jQuery code.

This piece of code was helpful for me and saved my day.. I improved it and it helped me for Impersonated user.. here is bellow ,what i did..

  <% if (Session["SessionUserImpersonate"] != null && Session["SessionUserImpersonate"] != "" && Session["SessionUserImpersonate"] == "Yes")
    {
        BLL.Models.User userold = new BLL.Models.User();
        userold = (BLL.Models.User)Session["SessionUserOld"];      
        %>
    <span class="FL">(Impersonated as <%=Website.Backoffice.SessionHelper.Session_User.UserName != null ? Website.Backoffice.SessionHelper.Session_User.UserName:"" %>  , </span>

    <form class="FL" id='frmid' action="/Index/Login?username=<%=userold.UserName%>&password=<%=userold.Password%>&IsImpersonate=No"  method="post">
                <a class="TxtRed" style="cursor:pointer;" onclick="$('#frmid').submit(); return false;" > - finish impersonated session  </a>
                </form>   
                ) &nbsp;&nbsp;
    <%} %>
