我有一个带有三个单选按钮的表单。When one of the radio buttons is selected I have another table show on the form. 验证未正确更新。它应该只显示对显示的表的验证。如果未显示付款表，我不想验证这些字段。
<script type="text/javascript">
$(document).ready(function() {
$('input[name="group1"]').change(function(){
if ($(this).val() == "charge")
{
$('#charge').css('display', 'inline');
}
else
{
$('#charge').css('display', 'none');
}
});
});*/

我不得不将验证更改为：
if ( ($("#selection").attr('checked') == false ) ) {
$("#errors").after('<span class="error">Please select an option.</span>');
hasError = true;
}
if ( ($("#selection").attr('checked') == true ) ) {
//validate cctype
if ( ($("#cctype").val() == '') ) {
$("#errors").after('<span class="error">Please select a credit card type.</span>');
hasError = true;
}
