使用jquery问题验证和提交表单

Question

I'm trying to submit form using j-query, before submitting it should do some validation and in that I've validation for capcha using ajax. Everything works fine without ajax validation.

<form id="RegistrationForm" name="RegistrationForm" method="post" action="save.php" >

jquery code

$('#RegistrationForm').submit(function(){
//some validation goes here
if($('#captcha').val() != '')
    { 
        var captcha = $('#captcha').val();
        $.ajax({
            url:'validate.php',
            type:'POST',
            data:{captcha:captcha},
            success: function(data){
                if(data == 'false')
                {
                    alert('Wrong Captcha is typed!');
                    return false;
                }
                else
                {
                                alert('enter');
                document.getElementById("RegistrationForm").submit();   
                                return true;

                }

              }
            });
    }
});`

while submitting form it shows alert "enter" but form not getting submitted. Thanks in advance.

You probably need to change your variable to a JSON seening how you are retreiving from a php. if thats not the solution try

if (data){

}else{

}

FYI this is not jquery validation. Jquery validation is a library set up in order to make sure the proper fields are set up correctly before submitting. What you have done is tested if the captcha is correct after submitting.
