当表单未经验证就提交时常见的问题是什么。前几天我通过验证让它工作正常，但现在它没有验证，只是提交。
这是一个使用 hide show 方法的多页表单，并且由于该函数在他的 form.submit 代码中，所以它也不起作用。我假设它被压倒了，但默认但使用 e.preventdefault() 只会导致提交/下一步按钮没有任何动作。
处理此问题时常见的小问题是什么，例如 jquery url 需要在表单之前，或者表单的脚本也需要在表单之前，等等。可能会意外删除 { 或 ; 是个问题？
这是我的表单脚本
<script type="text/javascript">
$('form#mainform').submit(function(e) {
var isValidYear = /^\d{4}$/.test(jQuery('#xxx').val());
var year_number = parseInt(jQuery('#xxxx').val());
var first_name = jQuery.trim(jQuery('#xxx').val());
var last_name = jQuery.trim(jQuery('#xxxx').val());
var form_email = jQuery.trim(jQuery('#xxxxx').val());
var street = jQuery.trim(jQuery('#xxxx').val());
var city = jQuery.trim(jQuery('#xxxx').val());
var state = jQuery.trim(jQuery('#xxxxx').val());
var isValidPhone = /^[2-9]\d{2}[2-9]\d{2}\d{4}$/.test(jQuery('#phone_day').val());
if(current_step == 1){
if(!jQuery('#step-1 input["radio"].required').is(":checked")){
alert('Please select xxxxxx');
}
else {
$('#mainform fieldset').hide();
$('#step-2').show();
current_step++;
}
return false;
}
if(current_step == 2){
if(!isValidYear || (year_number > <?php echo date('Y') ?>)){
alert('Please enter a Year.');
}
else {
$('#mainform fieldset').hide();
$('#step-3').show();
current_step++;
}
return false;
}
if(current_step == 3){
if(first_name.length <= 0 || first_name == 'First Name' || (!first_name.match(/[a-zA-Z]/)) || (first_name.match(/[0-9]/))){
alert('Please enter your First Name.');
}
else if(last_name.length <= 0 || last_name == 'Last Name' || (!last_name.match(/[a-zA-Z]/)) || (last_name.match(/[0-9]/))){
alert('Please enter your Last Name.');
}
else if(street.length <= 0 || street == 'Street Address'){
alert('Please enter your Street Address.');
}
else if(city.length <= 0 || city == 'City'){
alert('Please enter your City.');
}
else if(state.length <= 0 || state == 'State'){
alert('Please enter your State by 2 letter abbreviation.');
}
else if(country.length <= 0 || country == 'Other'){
alert('Please enter your Country.');
}
else if(!isValidPhone){
alert('If your phone number is correct, close this box and then Click the button in the form.');
}
else {
$('form#mainform').submit();
}
return false;
}
});
</script>
这是我在页脚中的验证网址
<script src="/jquery/jquery.validate.js"></script>
这是表格
