问题描述

有人能告诉我使用的 jQuery来显示成功的表单提交 *的的教程，而无需刷新页面的*。类似的事情发生在当消息被传递Gmail和黄色叠加显示您的邮件递送，然后褪色出局。 我要显示的信息取决于表单提交的结果。

Can someone show me a tutorial of using jquery to display successful form submission *without refreshing the page*. Something like that happens on gmail when a message is delivered and the yellow overlay that shows that you message was delivered and then fade outs. I want the message to be displayed depending on the result of the form submission.

推荐答案

好吧......这样的事情......但我没有尝试...所以用它就像教程。您也可以使用JSON

Ok ... something like this ... but I didn't try it ... so use it just like tutorial.. You can also use json

记者：

function processForm() { 
        $.ajax( {
            type: 'POST',
            url: form_process.php,
            data: 'user_name=' + encodeURIComponent(document.getElementById('user_name').value),
            success: function(data) {
                $('#message').html(data);
            }
        } );
}

HTML：

html:

<form action="" method="post" onsubmit="processForm();return false;">
<input type='text' name='user_name' id='user_name' value='' />
<input type='submit' name='submit' value='submit'/>
</form>
<div id='message'></div>

form_process.php

form_process.php

$user_name = $_POST['user_name'];
if(do something){
     echo "login success";
else{
     echo "login unsuccessful";
}
