基于bootstrap.js制作简洁模态登录框，点击按钮弹出登录框表单，输入账号，密码效果。这是一款响应式的弹窗登录框插件。
使用方法：
1、head引入css文件
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" />
2、head引入js文件
<script type="text/javascript" src="js/jquery-1.12.4.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
3、body引入HTML代码
<div class="modal fade" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
</div>
<div class="modal-body">
<h4 class="modal-title" align="center">登录框</h4>
<br/>
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="name" class="col-sm-offset-2 col-sm-2 control-label">账号</label>
<div class="col-sm-5">
<input type="text" class="form-control" id="name" placeholder="请输您的入账号">
</div>
</div>
<div class="form-group">

<div class="col-sm-5">

</div>
</div>
<div class="form-group">
<div class="col-sm-offset-4 col-sm-5">
<button id="submitBtn" type="submit" class="btn btn-default btn-block btn-primary">登陆</button>
</div>
</div>
</form>
</div>
<div class="modal-footer">
</div>
</div>
<!-- /.modal-content -->
</div><!-- /.modal-dialog -->

<script type="text/javascript">
$(function(){
