我的问题是，我得到的数据似乎总是当我试图创建一个帐户帐户
用户名必须是3至15个字符
并且从未创建帐户。
也让我困惑的是，页面重新加载获取到的login.html
create.html上表
<form action="create.php" method="post" id="createForm">
<div>
<div class="row">
<div class="12u">
<input type="text" name="Username" placeholder="Username" id="username"/>
</div>
</div>
<div class="row">
<div class="12u">
<input type="password" name="Password" placeholder="Password" id="password"/>
</div>
</div>
<strong id="strongText" style="display: none;"></strong>
<div class="row">
<div class="3u">
<input type="button" value="Create Account" id="create"/>
</div>
<div class ="6u"></div>
<div class="3u">
<input type="button" value="Have an account?" id="login"/>
</div>
</div>
</div>
</form>
create.html上的东西的JavaScript
$(document).ready(function() {
$("#create").click(function(e) {
e.preventDefault();
document.getElementById("create").disabled = true;
document.getElementById('strongText').innerHTML = "Creating account, please wait...<br>";
$("#strongText").fadeIn();
var username = $('#username').val();
var password = $('#password').val();
$.ajax({
type: 'POST',
data: {
username: username,
password: password
},
url: 'createCheck.php',
success: function(data) { //Receives the data from the php code
//console.log(data);
if (data == "Unavailable") {
document.getElementById('strongText').innerHTML = "Username Unavailable<br>";
document.getElementById("create").disabled = false;
} else if (data == 'Username must be between 3 and 15 characters') {
document.getElementById('strongText').innerHTML = data + "<br>";
document.getElementById("create").disabled = false;
