                $('#_4th_prize').attr('disabled','disabled');
                $('#_4th_prize').val('')
                $('#rest_prize').removeAttr('disabled');
            }else{
                           alert("You have entered "+field_val+" number");
            }
        }
        else{
            alert("You have entered wrong number"); 
        }
    }

I have calling tournamentPrize() function in onblur this field when i entered any number it is not showing the proper result. always display -1

I want to get my proper result when i will enter 2,4,8,16,32,64 and 128 But if i am entered any number except above number the result also showing wrong.

Suppose i want to enter 3 the alert box will be come alert("You have entered wrong number"); but it is showing alert("You have entered 3 number");

Please somebody help me

Maybe you are also searching a polyfill of .indexOf() for Internet Explorer < 9: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… — ˈvɔlə

function tournamentPrize(v){
        var myArray=[2, 4, 8, 16, 32, 64, 128];

        var field_val = +v; // convert value to number from string
        // OR var field_val = parseInt(v); OR var field_val = Number(v);

        if(myArray.indexOf(field_val) !== -1){ //entered valid value in array
            if (field_val==2) {
               ....
            } else if(field_val==4){
               .....
            } else{
               alert("You have entered "+field_val+" number");
            }
        }
        else{
            alert("You have entered wrong number"); 
        }
}
