純粹是為了打發時間，手寫了一個js的警報控件。
代碼如下：
<html> <head> <script type =“ text/javaScript”> var alertobj = new Object（）; VAR GeneralStyle = {Zindex：0，寬度：“ 200px”，高度：“ 100px”，邊界：“厚實的#cccccc”，背景：“ #ffffff”，位置：“絕對”，top：“ 35％”，左：“ 40％”} var txtStyle = var txtStyle = verv {textAlign：peration's peration's perition's perition's perition's perition：peration's perition：peration's perition：peration's peration。 “ 70％”，顏色：“＃333333”，fontweight：“ Bold”，OutlineColor：“＃3366ff”，Outlinestyle：“ Ridge”，OutlineWidth，OutlineWidth：“ thin”，// outline：“ thin ridge＃3366ff”，ninthhtml：ok oignhtml：“ ok oil oferobj = pertareals = nersals：nersal nertals：nersal nestle nertal nertless：nersal nertals nestlets： btnset：btnstyle，isexist：false} alertobj.createComponent = function（）{var component = document.createelement（greatelement（gragonments [0]）; var styles =參數[1]; for（styles中的var屬性）{if（styles [property]！= null）{try {component.style [property] = styles [property]; } catch（err）{document.write（err.name+“：”+property+“ <br/>”）; //設置屬性錯誤！ }}}返回組件; } alertobj.show = function（）{if（！this.isexist）{this.isexist = true; var bodyobj = document.body; BodyObj.Style.Zindex = -1; BodyObj.style.background =“＃999999”; var divoBj = this.createComponent（“ div”，this.generalset）; var txtObj = this.createComponent（“ p”，this.txtset）; txtobj.innerhtml = gragonments [0]; var btnobj = this.createComponent（“ button”，this.btnset）; btnobj.innerhtml = this.btnset.innerhtml; btnobj.onclick = function（）{bodyobj.style.zindex = 0; BodyObj.style.background =“”; Bodyobj.Removechild（DivoBj）; if（arperobj.isexist）{alertobj.isexist = false; }} divobj.appendchild（txtObj）; DivoBj.AppendChild（BTNOBJ）; Bodyobj.AppendChild（DivoBJ）; }}函數show（s）{alertobj.show（s）; } </script> </head> <body> <p onclick =“ show（'內部測試'）;”>單擊“ show nerver </p> </hody> </hody> </html>”
