我要把这在希望有人可能会看到一个错误，因为我已经讨论了这样的方式来很多次了。这是工作的罚款约十分钟但当时刚刚分手。

I'm throwing this up in hope that someone might spot a mistake because I've gone over this way to many times now. It was working fine for about ten minutes but then just broke.

我有一个codeigniter网站，有3个领域的一个非常简单的接触形式。我使用isHappy.js来验证表单，然后发送关闭服务器。 isHappy.js应停止AJAX功能，直到形式已经得到证实，但此部分没有发生。如果我点击提交按钮没有填写表单验证错误闪烁，但随后的AJAX调用时，形式提交。

I have a codeigniter website with a very simple contact form with 3 fields. I'm using isHappy.js to validate the form and then send off to the server. isHappy.js should stop the AJAX function until the form has validated but this parts not happening. If I click the submit button without filling out the form the validation errors flash up but then the ajax call is made and the form is submit.

 $(function() { 

 $('#contact-form').isHappy({
   fields: {

     '#email': {
       required: true,
       message: 'How can I reach you sans email??'
     },
     '#subject': {
       required: true,
       message: 'Can you give me a clue to what you inquiring about please'
     },
     '#body': {
       required: true,
       message: 'More details please....'
     }
   }
});

 $('#contact-form').bind('submit', function(e) {
                e.preventDefault();
                var query_params = $('#contact-form').serialize();

                $.ajax({
                    type: 'POST',       
                    url: 'http://website.dev:8080/contact/email/ajax',
                    data: query_params,
                    dataType: 'json',

                    success: function(string){
                        $('#contact-form').fadeOut('medium', function() {
                                $('#linkedin').after("<div style=\"clear:both;\" /><div id=\"contact-complete\" stlye=\"width:100%;height:200px;\"><h1>"+string+"</h1></div>").fadeIn('medium');        
                        });                                                             
                    }

                });
    });     
}); 

和HTML：

<form action="http://website.dev:8080/contact/email" method="post" accept-charset="utf-8" id="contact-form">        
<div class="contact-input">
    <input type="text" name="email" id="email" placeholder="Your email" value="" />
</div>
<div class="contact-input">
    <input type="text" name="subject" id="subject" placeholder="Subject" value="" />
</div>
<div class="contact-textarea">
    <textarea rows="10" placeholder="How can I help you?" name="body" id="body"></textarea>
</div>
<input type="submit" value="Send" id="contact-click" />

推荐答案

按照 happy.js文档，如果验证失败，发生两件事情：

According to the happy.js docs, If validation fails two things happen:

在该领域将获得不高兴类。 在该领域将获得＆LT;跨度＆GT; 前右等，同一个类 unhappyMessage的DOM 和任何领域的id的id是加 _unhappy 。 The field will get an unhappy class. The field will get a <span> right before it, in the DOM with a class of unhappyMessage and an id of whatever the field's id is plus _unhappy.

这纯粹是presentational。你必须检查的形式不你的AJAX调用之前，包含具有不高兴类的任何投入。

This is purely presentational. You'll have to check that the form does not contain any inputs with unhappy classes before your AJAX call.

var is_unhappy = false;
$('#contact-form div :input').each( function(i) {
    if ( $(this).hasClass('unhappy') ) {
        is_unhappy = true;
        return false;
    }
});
if(!is_unhappy){
    //do ajax.
}
