-

i want split radio button values form know option chosen is, price. value before | separator price , value after | option chosen.

<input type="radio" name="arm" value="50|1" id="split" required> option: 1<br> <input type="radio" name="arm" value="100|2" id="split" required> option: 2<br> <input type="radio" name="arm" value="150|3" id="split" required> option: 3<br>  <input type="radio" name="mechanism" value="50|1"> option: 1<br> <input type="radio" name="mechanism" value="100|2"> option: 2<br> <input type="radio" name="mechanism" value="150|3"> option: 3<br>  <input type="radio" name="base" value="50|1"> option: 1<br> <input type="radio" name="base" value="100|2"> option: 2<br>  <input type="radio" name="fabric" value="50|1"> option: 1<br> <input type="radio" name="fabric" value="50|2"> option: 2<br> <input type="radio" name="fabric" value="50|3"> option: 3<br>  <script>      jquery(":text[name='quantity'], :radio[name='arm'], :radio[name='mechanism'], :radio[name='base'], :radio[name='fabric']").change(function(){     var arm = jquery(":radio[name='arm']:checked");     var arr = arm.split('|');     var $mechanism = jquery(":radio[name='mechanism']:checked");     var $base = jquery(":radio[name='base']:checked");     var $fabric = jquery(":radio[name='fabric']:checked");     var $quantity = jquery(":text[name='quantity']");     if($arm.length ==1){         var = parseint($arm.val(arr[0]), 10);         var m = parseint($mechanism.val(), 10);         var b = parseint($base.val(), 10);         var f = parseint($fabric.val(), 10);         var q = parseint($quantity.val(), 10);         jquery("#result").val((a + m + b + f) * q);     }     });  </script>

i trying split values using: 

var arm = jquery(":radio[name='arm']:checked"); var arr = arm.split('|');

and passing value follows:

 var = parseint($arm.val(arr[0]), 10);

this not work. no jquery or javascript guru, should make work?

this line:

var arr = arm.split('|');

you need value of arm , split that.

var arr = arm.val().split('|');
