纯粹是为了打发时间 ， 手写了一个 JS 的 Alarm 控件。
代码如下 ：
<html> <kopf> <script type = "text/javaScript"> var alertObj = new Object (); var GeneralStyle = {Zindex: 0, Breite: "200px", Höhe: "100px", Grenze: "Dick solide #ccccc", Hintergrund: "#ffffff", Position: "Absolute", top: "35%", links: "40%"} var txtstyle = {Textalign: center "} var btnstyle:" links ","} var btnstyle ".
