// 随滚动条浮动
    $(\'.Step_points\').width($(\'.Leftbox\').width());
    var Step_points_top=$(\'.Step_points\').offset().top;
    $(window).scroll(function(){
        console.log($(window).scrollTop());
        if($(window).scrollTop()>Step_points_top){
            $(\'.Step_points\').addClass(\'fixed\');
        }else{
            $(\'.Step_points\').removeClass(\'fixed\');
        }
    });
