表单未使用绝对位置的validationEngine()插件提交

Question

我正在使用validationEngine jQuery 插件来验证我的网络表单。验证完成后，我想通过 ajax 提交表单。表单提交正常，无需附加验证引擎插件。验证有效，但 ajax 在完成后不会触发提交表单。我做错了什么：

jQuery("form#sign-up").validationEngine({
    onValidationComplete: function () {
        var first = $("input#first").val();
        var last = $("input#last").val();
        var email = $("input#email").val();
        var pass = $("input#pass").val();



        var dataString = 'first=' + first + '&last=' + last + '&email=' + email + '&pass=' + pass;

        //to send the ajax request  
        $.ajax({
            type: "POST",
            url: "./register.php",
            data: dataString,
            success: function () {
                $('#sign-up').html("<div id='message'></div>");
                $('#message').html("<h2>Thanks!</h2>")
                    .append("<p>We'll send you an email when infoFree is ready to Rock n' Roll.</p>")
                    .hide()
                    .fadeIn(500, function () {
                    $('#message').append("<img id='checkmark' src='./assets/images/check.png' />");
                });
            }
        });
    }
});

验证引擎会阻止表单实际提交，因此不必在 onValidationComplete 中执行所有操作，只需将其全部移至表单提交时的函数中即可：

$(document).ready(function() {
  $("form#sign-up").validationEngine();
  $("form#sign-up").submit(function(){
    var first = $("input#first").val();
    var last = $("input#last").val();
    var email = $("input#email").val();
    var pass = $("input#pass").val();

    var dataString = 'first='+ first + '&last=' + last + '&email=' + email + '&pass=' + pass;

    //to send the ajax request  
    $.ajax({
      type: "POST",
      url: "./register.php",
      data: dataString,
      success: function() {
        $('#sign-up').html("<div id='message'></div>");
        $('#message').html("<h2>Thanks!</h2>")
        .append("<p>We'll send you an email when infoFree is ready to Rock n' Roll.</p>")
        .hide()
        .fadeIn(500, function() {
          $('#message').append("<img id='checkmark' src='./assets/images/check.png' />");
        });
      } 
    });
  });
}); // ready
