Question

<form action="1.html">
    <input type="radio" id="check1" name="check" />
    <input type="radio" id="check2" name="check" />
</form>

What I want to implement is :

when “check2” is checked,change “action” value to “2.html”

when “check1” is checked,change “action” value back to “1.html”

Answer 1

This should take care of your problem.

$(function(){
    $('#check1').click(function() {
        $(this).parent().attr('action', '1.html');
    });

    $('#check2').click(function() {
        $(this).parent().attr('action', '2.html');
    });
});
