i have radiobutton in view. binding values radiobutton db. after selection using jquery want send selected value of radiobutton controller. here view code.

@{     viewbag.title = "permmapping";     layout = "~/views/shared/_layoutc3card.cshtml";     list<c3card.dal.edmodel.ts_grp_perm_mapping> tmgrp1 = (list<c3card.dal.edmodel.ts_grp_perm_mapping>)viewbag.selectedcheckboxes; }  script type="text/javascript">     $.ajax({         type: 'post',         url: '/grpcontroller/savenewuser',         data: { usr_groupid: $('#ddl_group').val() },         datatype: 'json',         success: function (data) {             alert('user saved successfully.');             $('#tbluserregistration').empty();         }     });  </script> 

this table

<table id="tbluserregistration">     <tr>         <td>             <div class="form-box form-box-default">                 @html.dropdownlist("ddl_group", viewbag.list selectlist, "--select--")             </div>         <td>     </tr>     <tr>         <td>             <div>                 <ul>                     @{ int row = 0; }                     @foreach (c3card.dal.edmodel.tm_perm_level obj in tmgrp)                     {                         <li>@html.radiobutton("mid",obj.perm_id)@obj.perm_levelname</li>                     }                 </ul>             </div>         </td>     </tr> </table> 

here want selected radiobutton id want send controller using javascript.

this controller code.

public actionresult index() {     list<tm_perm_level> tm_perm_level = grppermbal.getallpermtype();     viewbag.chklist = tm_perm_level;     // list<tm_grp_group> tm = userservice.getallgroup();     viewbag.list = new selectlist(grppermbal.getallgroup(), "grp_id", "grp_name");     return view("~/views/grpcontroller/permmapping.cshtml"); }  public jsonresult savenewuser(int usr_groupid,string usr_doctypeids) {     list<ts_grp_perm_mapping> ts_grp_perm_mapping = grppermbal.getdata(usr_groupid);     viewbag.selectedcheckboxes = ts_grp_perm_mapping;          int result = grppermbal.savenewuser(usr_groupid,usr_doctypeids);     return json(result, jsonrequestbehavior.allowget); } 

to value of selected radio button can use

var selected = $('[name="mid"]:checked').val()); 

so ajax data options becomes

data: { usr_groupid: $('#ddl_group').val(), usr_doctypeids: selected }, 

which bind value of selected option string usr_doctypeids parameter in savenewuser() method
