我需要编写一个函数来“取消选中”组中的旧“选中”框。基本上，是A组和B组，一旦检查并提交了A组的项目，它显示了A组的项目以及与B组相同的内容B组的相同内容。A组的项目仍然出现。jQuery中是否有任何内置函数可以解决问题。代码设置在http://jsfiddle.net/rexonms/mJgcK/

还有 jQuery 1.2.6（我没有使用更新版本的特权）
$(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
});
});
