在滑到下一组问题之前，我正在尝试验证每张幻灯片上的表格。
除了单选按钮外，一切似乎都很好。如果未选中一个按钮并且如果选中了答案，则我正在尝试向一组按钮添加一类“错误焦点”，除了 return $error = false;
这是表格http://www.foresightaus.com.au/form/
$nextBtn.click(function(e){
e.preventDefault();
var newIndex = 0,
currentSlide = $slide.eq(currentIndex),
$text = currentSlide.find($('li input[type="text"]')),
$email = currentSlide.find($('#yourEmail')),
$radio = currentSlide.find($('li.radio-btns')),
formFields = currentSlide.find("input:text, li.radio-btns"),
$error = true;
formFields.removeClass("error-focus");
//-----------------------------------------------------------------
//-- Validate Text Fields
$text.each(function(){
if($(this).val()==""){
//errorMessage("Please Enter Your Name");
$(this).focus().addClass("error-focus");
$error = true;
}else{
$error = false;
}
}); // end text each

if($error = false){
if(currentIndex<lastIndex){
newIndex = currentIndex+1;
}
slideToImage(newIndex);

});
function isValidEmail(email) {
var emailRx = /^[\w\.-]+@[\w\.-]+\.\w+$/;
return emailRx.test(email);
}
