Question

var id = "<?php echo $val->id; ?>";

var myRadio = $('input[name=<?php echo "mala".$val->id; ?>]').val();

if (myRadio.val.length > 0){
   $("#anketa").load('http://www.svastara.rs/anketa/anketa_m1_data', 
       { answer: myRadio, id: id });
   }
});

Why this if (myRadio.val.length > 0) returns it looks like false, when i am sure that there is something in the string. If its not a good way, how to check that the string is empty or not?

Answer 1

No need in val, since you should already get the value with val() method in the previous line:

if (myRadio.length > 0) { ... }
