提交表单后，我想重置表单以显示原始空白值。这是代码：
PHP Form
<form action="index.php" method="post" id="contact_form" >
<div id="topic_error" class="error"><img src="images/error.png" /> What category should this be filed in?</div>
<div>
<select name="topic" id="topic">
<option value="">Please select a topic...</option>
<option value=" Computer Repair ">Computer Repair</option>
<option value=" Website Design ">Website Design</option>
<option value=" Say Hi ">Just Want to Say Hi</option>
</select>
</div>
<h4>NAME:</h4><div id="name_error" class="error"><img src="iamges/error.png" /> Please enter your name</div>
<div><input class="contact_name" type="text" name="name" id="name" placeholder="Enter Name" /></div>
<H4>EMAIL:</H4><div id="email_error" class="error"><img src="images/error.png" /> Please enter your email</div>
<div><input class="contact_email" type="text" name="email" id="email" placeholder="you@mail.com" /></div>
<h4>SUBJECT:</h4><div id="subject_error" class="error"><img src="images/error.png" /> Please enter a subject</div>
<div><input class="contact_subject" type="text" name="subject" id="subject" placeholder="How did you become so awesome?" /></div>
<h4>MESSAGE:</h4><div id="message_error" class="error"><img src="images/error.png" /> Please give us a few more details</div>
<div><textarea class="contact_message" name="message" id="message" placeholder="Give us some details"></textarea></div>
<div id="mail_success" class="success"><img src="images/success.png" /> Thank you. The mailman is on his way.</div>
<div id="mail_fail" class="error"><img src="images/error.png" /> Sorry, we don't know what happened. Please try again later.</div>
<div id="cf_submit_p">
<input class="submit" type="submit" id="send_message" value="">
</div>
</form>
contact.js 文件
$(document).ready(function(){
$('#send_message').click(function(e){
e.preventDefault();
var error = false;
var topic = $('#topic').val();
var name = $('#name').val();
var email = $('#email').val();
var subject = $('#subject').val();
var message = $('#message').val();
if(topic.length == 0){
var error = true;
$('#topic_error').fadeIn(500);
} else {
$('#topic_error').fadeOut(500);
}
if(name.length == 0){
var error = true;
$('#name_error').fadeIn(500);
} else {
$('#name_error').fadeOut(500);
}
if(email.length == 0 || email.indexOf('@') == '-1'){
var error = true;
$('#email_error').fadeIn(500);
} else {
$('#email_error').fadeOut(500);
}
if(subject.length == 0){
var error = true;
$('#subject_error').fadeIn(500);
} else {
$('#subject_error').fadeOut(500);
}
if(message.length == 0){
var error = true;
$('#message_error').fadeIn(500);
} else {
$('#message_error').fadeOut(500);
} if(error == false){
$('#send_message').attr({'disabled' : 'true', 'value' : 'Sending...' });
$.post("send_email.php", $("#contact_form").serialize(),function(result){
if(result == 'sent'){
$('#cf_submit_p').remove();
$('#mail_success').fadeIn(500);
} else {
$('#mail_fail').fadeIn(500);
$('#send_message').removeAttr('disabled').attr('value', 'Send Message');
}
});
}
});
});
我认为不需要 send_email.php 文件，但如果需要，我可以将它放在这里。我会假设（我知道当你假设时会发生什么）这可以通过 javascript 中的某种触发器来完成。我确实尝试在该行form.trigger('reset');之后添加该行，$('#mail_success').fadeIn(500);但这不起作用
