一款html5+CSS3实现的超炫酷的登录表单,按照页面提示的用户名和密码输入正确,并输入显示的验证码,点击“登录”按钮显示验证动画效果,同时页面全屏化显示,验证成功后进入登录成功的界面,整个页面一直会有动感的粒子背景显示,整体效果相当的酷炫。

页面的head部分,需引入四个CSS样式文件,代码如下:

<link type="text/css" rel="stylesheet" href="css/default.css" />
<!--必要样式-->
<link type="text/css" rel="stylesheet" href="css/styles.css" />
<link type="text/css" rel="stylesheet" href="css/demo.css" />
<link type="text/css" rel="stylesheet" href="css/loaders.css" />

页面的body部分,用了多个div容器的嵌套,代码如下:

<div class='login'>
	<div class='login_title'>
		<span>管理员登录</span>
	</div>
	<div class='login_fields'>
	    <div class='login_fields__user'>
	      <div class='icon'>
	        <img alt="" src='img/user_icon_copy.png'>
	      </div>
	      <input name="login" placeholder='用户名' maxlength="16" type='text' autocomplete="off" value="Richer"/>
	      <div class='validation'>
	        <img alt="" src='img/tick.png'>
	      </div>
	    </div>
	    <div class='login_fields__password'>
	      <div class='icon'>
	        <img alt="" src='img/lock_icon_copy.png'>
	      </div>
	      <input name="pwd" placeholder='密码' maxlength="16" type='text' autocomplete="off">
	      <div class='validation'>
	        <img alt="" src='img/tick.png'>
	      </div>
	    </div>
	    <div class='login_fields__password'>
	      <div class='icon'>
	        <img alt="" src='img/key.png'>
	      </div>
	      <input name="code" placeholder='验证码' maxlength="4" type='text' name="ValidateNum" autocomplete="off">
	      <div class='validation' style="opacity: 1; right: -5px;top: -3px;">
          <canvas class="J_codeimg" id="myCanvas" onclick="Code();">对不起,您的浏览器不支持canvas,请下载最新版浏览器!</canvas>
	      </div>
	    </div>
	    <div class='login_fields__submit'>
	      <input type='button' value='登录'>
	    </div>
	</div>
	<div class='success'></div>
	<div class='disclaimer'>
	    <p>欢迎登陆后台管理系统</p>
	</div>
</div>
<div class='authent'>
  <div class="loader" style="height: 44px;width: 44px;margin-left: 28px;">
    <div class="loader-inner ball-clip-rotate-multiple">
        <div></div>
        <div></div>
        <div></div>
    </div>
    </div>
  <p>验证登录中...</p>
</div>
<div class="OverWindows"></div>

页面的底部,需引入layui的样式文件、jQuery库和其余的JS文件,并设置好验证码等的事件响应,代码如下:

<link type="text/css" rel="stylesheet" href="layui/css/layui.css" />
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery-ui.min.js"></script>

<script type="text/javascript" src="Js/Treatment.js"></script>
<script type="text/javascript" src="js/jquery.mockjax.js"></script>
<script type="text/javascript">

var truepwd = "freedom";

var CodeVal = 0;
Code();
function Code() {
	if(canGetCookie == 1){

	}else{

	}
}
function showCheck(a) {
	CodeVal = a;
    var c = document.getElementById("myCanvas");
    var ctx = c.getContext("2d");
    ctx.clearRect(0, 0, 1000, 1000);
    ctx.font = "80px 'Hiragino Sans GB'";
    ctx.fillStyle = "#E8DFE8";
    ctx.fillText(a, 0, 100);
}
$(document).keypress(function (e) {

    if (e.which == 13) {
        $('input[type="button"]').click();
