jquery dynamic radio button validation

Question

I have created 20 radio button dynamically

 <script>

$(function() {

    $( "#sortable1, #sortable2" ).sortable({

        connectWith: ".connectedSortable"

    }).disableSelection();

    $( "#sortable2" ).sortable({

       remove: function(event, ui) { 

           t = ui.item[0].attributes['id'].nodeValue;


          k = $("input[name='"+t+"' ]");


          k.remove();

       },


       receive: function(event, ui) { 

           //itemid = ui.item[0].attributes['id'];

        t = ui.item[0].attributes['id'].nodeValue;   
        $("#element").append( "<br/>" +ui.item[0].innerHTML.trim() );
            for(i=1; i<=20; i++)
            { 
                j=$("#over" + i).append("<br/> <td><input type=radio name='"+ui.item[0].innerHTML.trim()+"' value='"+i+"'></td> <br/>");
               var radVal=$("#over" + i+":checked").val();
  alert(radVal);
            }

}


    });        

});

` 'Player';

for($j=1;$j<=20;$j++)

{

echo '<th align="center">'.$j.'</th>';

}

echo '';

echo ""; { echo ""; echo ""; echo "";

for($i = 1; $i <=20; $i++) { echo "";
echo "";
echo ""; }
} echo "";

?> `

my question is that how to check validation value

Answer 1

var temp = $('#over1:checked').val();

要么

 var temp = $('#over1').val();

Answer 2

Change the code where you generate the radiobutton to: (Add the value attribute)

<input type=radio name='"+ui.item[0].innerHTML.trim()+"' value='"+i+"'> 

After adding all the radio button if you call this function on any click event

function getChecked(){
     var radVal=$("input[name=nameOfRadiobuttons]:checked").val();

     alert(radVal);
}

Put a button on th HTML Page calling the function

<input type=button onclick='getChecked()'>

radVal will give the index of the checkbox selected..If its undefined then you might not have checked any radio button
