基于Layui Layer组件实现提现弹窗与表单验证

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>弹出层</title>
  <link rel="stylesheet" href="/static/layui/css/layui.css" rel="external nofollow" rel="external nofollow" >
  <script src="/static/layui/jquery.min.js"></script>
</head>
<body>
<span id="pro" ><font size="10">申请提现</font></span>
</body>
 
<script src="/static/layui/layui.js"></script>
<script type="text/javascript">
 
  $('#pro').on('click',function(){
    //提现弹窗之前进行一定判断伪代码
    //上述条件符合之后,弹出提现弹窗
    layui.use('layer', function() {
      var layer = layui.layer;
      layer.open({
        type: 2,
        // skin: 'layui-layer-molv',
        title: '申请提现',
        content:['/kk.php','no'] ,//不允许出现滚动条
        area:['600px', '400px']
      });
    });
 
  // });
})
  
</script>
</html>
