如何通过Ajax提交和验证表单
问题描述:
请尝试通过使用Ajax同时向我的数据库提交并验证我的表单,但是它对我不起作用. 这是我的jQuery
Please I am trying to simultaneously submit and validate my form to my database through the use of Ajax, but it is not working for me. Here is my jquery
$(document).ready(function(){
$(".button").click(function(){
$("#myform").validate();
//Ajax to process the form
$.ajax({
type: "POST",
url: "process.php",
data: { firstname: $("#firstname").val()},
success: function(){
$('#message').html(data);
}
});
return false;
});
});
问题是当我提交表单时,Ajax表单提交给自己. 请问什么是将jquery validate和$ .ajax一起使用的正确方法?
The problem is when I submit the form,the Ajax form submit to itself. Please What is the right way to use the jquery validate and $.ajax together?
答
尝试一下(按预期方式为我工作):
Try this (working for me as expected):
HTML表单:
<link rel="stylesheet" href="http://jquery.bassistance.de/validate/demo/css/screen.css" />
<script src="http://jquery.bassistance.de/validate/lib/jquery.js"></script>
<script src="http://jquery.bassistance.de/validate/jquery.validate.js"></script>
<script>
// JQuery Script to submit Form
$(document).ready(function () {
$("#commentForm").validate({
submitHandler : function () {
// your function if, validate is success
$.ajax({
type : "POST",
url : "process.php",
data : $('#commentForm').serialize(),
success : function (data) {
$('#message').html(data);
}
});
}
});
});
</script>
<form class="cmxform" id="commentForm" method="get" action="">
<fieldset>
<p>
<label for="cname">Name (required, at least 2 characters)</label>
<input id="cname" name="name" minlength="2" type="text" required />
<p>
<label for="cemail">E-Mail (required)</label>
<input id="cemail" type="email" name="email" required />
</p>
<p>
<label for="curl">URL (optional)</label>
<input id="curl" type="url" name="url" />
</p>
<p>
<label for="ccomment">Your comment (required)</label>
<textarea id="ccomment" name="comment" required></textarea>
</p>
<p>
<input class="submit" type="submit" value="Submit" />
</p>
</fieldset>
</form>
<div id="message"></div>
PHP代码:
<?php
echo $_POST['email'];
?>
