Radio buttons and textfield script

[damipera]

hi guys, can you give me some ideas as to how i should deal with this?

i have 3 radio buttons (all with the same name and have values 1,2 and 3) and a textfield.

i want to have a javascript that makes the textfield mandatory when radio button 2 OR 3 is selected.

any ideas guys please?

thanks.

Add a check into your submit/validation routine


if (radiobutton.value == 2 || radiobutton.value == 3) {
//

you will need to check for the checked property too, as the radio button always has a value.

attach an event to the onchange event of each radiobutton and in the function test for which radio is selected and whether its value is 2 or 3; then act accordingly

in jQuery

$("input[type="radio"]").on('click', function(e){
 if($(this).is(":checked")){
   if($(this).val() == 2 OR $(this).val() == 3 ){
     //make things mandatory
   }
 }
});
