http://jsfiddle.net/u6Lbuwwe/1/

Below is the HTML code







Below is the jQuery code

$(document).ready(function(){
        var i=0;
    $("input:checkbox").click(function(){
            $('tr td').each(function{
                if($(this).find('checkbox').is(':checked'))
                    i++;
            });
        });
        if(i==3)
            $("input:checkbox").not(':checked').prop('disabled',true);
        else
            $("input:checkbox").not(':checked').prop('disabled',false);

i tried your fiddle. add jQuery and it should work

$(document).ready(function(){
    var i=0;
    var chkBox = $("input[type=checkbox]");
    chkBox.click(function(){
        var i = 0;
        chkBox.each(function(){
            if($(this).is(':checked')) i++;
        });
        if(i==3)
            chkBox.not(':checked').prop('disabled',true);
        else
            chkBox.not(':checked').prop('disabled',false);  
    });

});
