javascript - Get asp.net RadioButtonList selected value with jQuery -

i want uncheck radiobuttonlist if click on listitem yet checked. code of radio:

<div class="filtrodiv100" style="margin-top: 17px;">                 <asp:radiobuttonlist id="rbttipi" runat="server" onclick="resetfun();" style="margin-top: 4px; margin-bottom: 8px;">                     <asp:listitem value="industriale">&nbsp; addizionale regionale industriale</asp:listitem>                     <asp:listitem value="civile">&nbsp; addizionale regionale civile</asp:listitem>                     <asp:listitem value="sostitutiva">&nbsp; addizionale regionale sostitutiva</asp:listitem>                     <asp:listitem value="imposta">&nbsp; imposta gas</asp:listitem>                 </asp:radiobuttonlist>             </div> 

my function:

<script type="text/javascript" >     function resetfun() {         var radiobuttons = $('#<%=rbttipi.clientid%>');       var id= $(this).attr('value')         }     }  </script>  

firstly, onclick attribute should onchange. because onchange captures change onclick fires after clicked , before change happens.

write resetfun() function below.

function resetfun() {     var radiobuttons = $('#<%=rbttipi.clientid%>');     var id = radiobuttons.find('input:checked').val(); // selected value } 

alternative solution:

write onchange attribute onchange="resetfun(this);". pass radio button list element parameter javascript function.

and resetfun function below:

function resetfun(radio) {     alert($(radio).find('input:checked').val()); }
