jquery radio button when checked need an alert

Question

Hello

In my application i need a radio group, in which whenever a button is checked, an alert occur so that i can post its value to ajax post in jquery.

Can you help me please how i can do it in jquery?

Answer 1

Try something like this:

$(function(){
  $('input[type="radio"]').click(function(){
    if ($(this).is(':checked'))
    {
      alert($(this).val());
    }
  });
});

If you give your radio buttons a class then you can replace the code $('input[type="radio"]') with $('.someclass').

Answer 2

$('#radioId').click(function() {
        if ($(this).is(':checked')) {
      // put your code here and your alert
   }
}

Answer 3

$("input[type=radio]").change(function(){
    alert( $("input[type=radio][name="+ this.name + "]").val() );
});
