How to set radio option checked onload with jQuery?

Need to check if no default is set and then set a default

Answer 1

If you want it to be truly dynamic and select the radio that corresponds to the incoming data, this works. It's using the gender value of the data passed in or uses default.

if(data['gender'] == ''){
 $('input:radio[name="gender"][value="Male"]').prop('checked', true);
}else{
  $('input:radio[name="gender"][value="' + data['gender'] +'"]').prop('checked', true);
};
