本文实例效果其实就是一个点击弹窗效果，供大家参考，具体内容如下

先上jquery代码

//模态框垂直居中 function centerModals() { $('.modal').each( function(i) { var $clone = $(this).clone().css('display', 'block') .appendTo('body'); var top = Math.round(($clone.height() - $clone.find( '.modal-content').height()) / 2); top = top > 0 ? top : 0; $clone.remove(); $(this).find('.modal-content').css("margin-top", top - 50); }); } $('.modal').on('show.bs.modal', centerModals); $(window).on('resize', centerModals);

html代码

<!--登陆弹窗--> <form action="__URL__/doLogin" method="post" class="form-horizontal"> <!--模态框声名--> <div class="modal" id="myModal" tabindex="-1"> <!--窗口声名--> <div class="modal-dialog modal-sm"> <!--内容声名--> <div class="modal-content"> <div class="modal-header"> <button class="close" data-dismiss="modal"> <span>&times;</span> </button> <h4 class="modal-title">用户登录</h4> </div> <div class="modal-body"> <div class="form-group has-success has-feedback"> <label for="username" class="col-sm-3 control-label">账号</label> <div class="col-sm-9"> <span class="glyphicon glyphicon-user form-control-feedback" aria-hidden="true"></span> <span id="inputSuccess3Status" class="sr-only">(success)</span> <input type="text" id="username" name="username" class="form-control" placeholder="请输入您的用户名" title="可包含中文数字和常用字符" onkeydown="if(event.keyCode==32||event.keyCode==13){return false;}"> <!-- 禁用空格和回车 --> </div> </div> <div class="form-group has-success has-feedback"> <label for="password" class="col-sm-3 control-label">密码</label> <div class="col-sm-9"> <span class="glyphicon glyphicon-lock form-control-feedback" aria-hidden="true"></span> <span id="inputSuccess3Status" class="sr-only">(success)</span> <input type="password" id="password" name="password" class="form-control" maxlength="12" placeholder="请输入您的密码" oncopy="return false" oncut="return false" onpaste="return false" title="" onkeydown="if(event.keyCode==32||event.keyCode==13){return false;}"> </div> </div> </div> <div class="modal-footer"> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <button type="submit" class="btn btn-success" id="login">现在登录 »</button> </div> </div> </div> </div> </div> </div> </form>
