仿微信支付密码的弹框

问题：pc端，在用户选择完支付方式之后，点击 -‘ 确认支付 ’ 时，需要输入密码，此时需要一个输入密码的弹出框。

下面就来写一下，静态页面（比较粗略：）：

看一下-----html代码：

<!-- 支付密码-弹框 start -->
<div class="goPayTanKuang" style='display:none;'>
    <div class="payChoose_tk">
        <div class="payChoose_in">
            <div class="payChooseTotal clearAfter">
                <div class="orderNum">订单编号：DD154563267899675</div>
            </div>
            <div class="line"></div>
            <div class="payStyle" style='font-size:34px;'>￥880</div>
            <ul class="clearAfter">
                <li><input type="password" name="" maxlength="6" οninput="goPayTkInput()"></li>
            </ul>
            <a class="goPay" href="javascript:;">确定</a>
            <div class="close" οnclick="$('.goPayTanKuang').hide()">
                <img src="img/payChooseGbi.png" alt="">
            </div>
        </div>
    </div>
</div>
<!-- 支付密码-弹框 start -->

css样式：

         是在之前的弹框基础上改的，这里就不简化了:）
