jq实现 元素显示后 点击页面的任何位置除元素本身外 隐藏元素

$(".share-weixin").on("click",function(e){
        var $wx=$(".weixin-share"),_winW=$(window).width(),_winH=$(window).height(),_winScrollT=$(window).scrollTop(),_winScrollL=$(window).scrollLeft();
        $wx.css({"display":"block",left:_winW/2-125+_winScrollL+"px",top:_winH/2-132+_winScrollT+"px"});

        e.stopPropagation();
        $wx.on("click",function(e){
            e.stopPropagation();
        });
        $("body").one("click",function(e){
            $(".weixin-share").css("display","none");
        });
    });
