fedora15修改显示器刷新率
当前用户的显示器刷新率设置在当前用户目录下.config文件夹下的monitors.xml里。
vi ~/.config/monitors.xml
<rate>60</rate>
默认是60，修改成85后，保存退出monitors.xml

把一个元素放在屏幕的中心位置
jQuery.fn.center = function () {
this.css('position','absolute');
this.css('top', ( $(window).height() - this.height() ) / +$(window).scrollTop() + 'px');
this.css('left', ( $(window).width() - this.width() ) / 2+$(window).scrollLeft() + 'px');
return this;
}
//这样来使用上面的函数：
$(element).center();
