How to access dropdown text (not value) using Requ

问题:

I am working on MVC 4.0.

I need to access my dropdown box Text (not value) using Request.Form("ddlId") in my controller code.

and display the selected info on confirmation page of registration.

i.e. lets consider I am having Country dropbox as below.

 <select data-val="true" data-val-required="Required" id="CountryId" name="CountryId" style="width:210px"><option value="">--Select--</option><option value="1">USA</option><option value="2">UK</option></select>

now, in controller when i use,

            objWizard.CountryId = Request.Form["CountryId"];

I got the value of COuntry dropbox, not the text selected by user.

How can i select text of dropbox using Request.Form(...)????

Or any alternative........

My jquery code is as below.

   $.post( '@Url.Action("ConfirmDetails", "Wizard")', $("form").serialize(), function (r)
                    {
                        // inject response in confirmation step
                        //$(".wizard-step:visible")
                        $("#confirmdiv").html(r);
                    });

i'll assume that you are posting a form and that look likes

<form>
<select id="CountryId">
  <option value=1>US</option>
  <option value=2>UK</option>
</select>
<input type="submit" value="submit" id="btnSubmit"/>
</form>

on form submit cancel the default behavior

$("#btnSubmit").click(function(e){
e.preventDefault();
//now make a hidden field here and put the text of selected option in that 
var selectedOption = $("#CountryId option:selected").text();
$("<input/>",{type:'hidden',name:'CountryName'}).val(selectedOption).appendTo("form");
// now post the form 
$.post( '@Url.Action("ConfirmDetails", "Wizard")', $("form").serialize(),function (r)
  {
   // inject response in confirmation step
   //$(".wizard-step:visible")
   $("#confirmdiv").html(r);
  });
});

in the controller

[HttpPost]
public ActionResult ConfirmDetails()
  {

   var countryName = Request.Form["CountryName"];
  }

You can use JQuery post for this,

var selectedLi=$('#CountryId option:selected');

$.post('controller/action',{CountryId :selectedLi.val(),CountryName:selectedLi.text() }, function(data) {
  $('.result').html(data);
});

And in your action you can get those values like this,

 public ActionResult Action(string CountryName,string CountryId )
  {

//...........
  }

You could emit the value tag as the country name on the server and prevent any need for javascript.

<select id="CountryId">
  <option value="US">US</option>
  <option value="UK">UK</option>
</select>

You can use, ddlHospitalName.Items.FindByValue(Convert.ToString(Request.Form["ctl00$contentPlaceHolder$ddlHospitalName"])).Text;
