Use jquery to implement the Mask Layer

<Div style = "display: none" id = "yinying"> </div> <script type = "text/javascript"> function showUnitInfo () {var screenWidth = $ (window ). width (); // the current window width var screenHeight = $ (window ). height (); // the current window height $ ("# yinying" ).css ({"display": "", "position": "fixed", "background ": "#000", "z-index": "1001", "-moz-opacity": "0.5", "opacity ":". 50 "," filter ":" alpha (opacity = 50) "," width ": screenWidth," height ": screenHeight}) ;}</script>

 

Written by jquery. class libraries must be referenced before use. First, write a div that is not displayed. When an event is triggered, add a style to the div. The height is the current window height and the width is the current window width.
