jQuery实现鼠标滑过遮罩并高亮显示效果

<script type="text/javascript">
    $(function() { 
        var conAry = $("[name=h_light]"); 
        conAry.each(function(){ 
        var $this = $(this); 
        var els = $("a", $this); 
        els.each(function(){ 
        var el = $(this); 
        el.mouseover(function() { 
        els.css({ "opacity": 0.2}); 
        el.animate({ "opacity": 0.9 }); 
        }); 
        }); 
        $this.mouseout(function() { 
        els.css("opacity", 1); 
        }); 
        }); 
        });
