Question

I need write a function that will “uncheck” the old “checked” boxes with in a group. Basically, are group A and group B and once items from group A is checked and submitted, it shows the items from group A and same thing with group B. But the issue is when item from group A is selected and displayed and you do the same thing from group B. The items form group A still shows up. is there any built in function in jQuery that will do the trick. The code is set up at http://jsfiddle.net/rexonms/mJgcK/

And the jQuery 1.2.6 (I don’t have privilege to use newer version)

$(document).ready(function(){

$('.option').hide();//Hiding all options
$('.answer').hide(); //Hiding all the answers   
$('#showMeContainer').hide(); //Hiding the show me button
$('.answerTitle').hide();


$('.selectOne').change(function(event){


    var name = $('.selectOne option:selected').attr('name');
    //alert(name);
    $('#showMeContainer').hide(); 
    $('.option').hide();
    $('.' + name).show();
    $('#showMeContainer').show(); 


});

$('#showMe').click(function(event) {  
    $('.answer').hide();
    $('.answerTitle').hide();
    var checked = $('.option').find(':checked');
    $.each(checked, function() {
        var name = this.name;
        $('.' + name).show();
         $('.answerTitle').show();

    });

    var x = $('#compBody').height() + 50;// Getting the height on the div
    $('#pageBody').css('height',x); // updating the height of the outer div

});
});​

Answer 1

Just add the following line

$(".options [type=checkbox]").attr('checked', false);

In $('.selectOne').change()

That will uncheck all checkboxes when the list selection changes.
