我正在尝试使用jquery ajax调用将用户添加到数据库.用户可以很好地添加到数据库中,但是ajax总是返回错误.我不知道如何检索特定的错误.下面是我的代码,表单,php和jquery.
这是jquery
$(document).ready(function() {
//ajax call for all forms.
$('.button').click(function() {
var form = $(this).closest('form');
$.ajax({
type: "POST",
url: form.attr('data'),
dataType: 'json',
data: form.serialize(),
success: function (response) {
alert('something');
},
error: function() {
alert('fail');
}
});
});
});
这是PHP
<?php
include 'class_lib.php';
if(isset($_POST['username'])) {
$user = new Users;
$user->cleanInput($_POST['username'], $_POST['password']);
if($user->insertUser()) {
echo json_encode('true');
} else {
echo json_encode('false');
}
}
这是HTML
<div id='newUser' class='tool'>
<h3>New User</h3>
<form method='post' name='newUser' data='../php/newUser.php'>
<span>Username</span><input type='text' name='username'><br>
<span>Password</span><input type='password' name='password'>
<input type='submit' …我正在尝试将使用jquery的类添加到第n个子项，以便它将在IE中工作。它似乎不起作用，我遵循了一些没有结果的示例。我把小提琴挂了
