The principle is Add a hidden DIV layer with id="brg" and a width and height of 100% on the masked layer. This layer will be displayed when a button is clicked, so that the masked layer cannot be clicked and the focus is lost. Set the Z-axis position of the popped-up layer (determination window): Z-INDEX is the highest.

<span style="font-size:12px;"><div id="brg"></div><div id="showdiv"><div class="btn"><a href="#" id="close"><span >取消</span></span></a></div></div><a href="#" id="lay"><span>确定</span></a></span>

#brg{width:100%; height:100%;filter:alpha(opacity=60); -moz-opacity:0.6; opacity: 0.6; display:none;}#showdiv{z-index:20; display:none; }

2014-8-19: New Mask layer implementation: compatible with ie6:

<div id="brg"></div><div class="vip_none"><div class="close_btn"><a href="javascript:void(0)" id="close_btn"><img src="images/close_btn.png" height="23" width="23"></a></div><p>VIP充值尚未开放<br><br> 敬请期待～</p></div>
