                var elem = e.target || e.srcElement;  
                while (elem) { //循环判断至跟节点，防止点击的是div子元素

                $(\'#test\').css(\'display\', \'none\'); //点击的不是div或其子元素。。这里可以更改其他的内容
/*if ( $(\'#side_shop_cart\').hasClass(\'sh-hi\') ) {

$(\'.shop-car-sider\').animate({left:\'35px\',opacity:\'hide\'},\'normal\',function(){

$(\'.shop-car-sider\').removeClass(\'sh-hi\');

    <body>  
        <div id="test" style="width: 300px; height: 300px; background-color: #CBC7BC;">  
            div测试内容，点击其它地方会隐藏此div模块。
