在http://www.aceona.com/网站发现的模拟alert confirm的插件。 http://labs.abeautifulsite.net/archived/下有好几个别的组件，jQuery-alerts,jquery-fileTree,jquery-multiSelect这三个是比较有用的，jQuery-alert的demo网址：http://labs.abeautifulsite.net/archived/jquery-alerts/demo/ jQuery-alert有jAlert(msg),jConfirm(msg,title,callback),jPromt(msg,value,title,callback)四种形式， 1.msg可以用样式。 2.这几个的样式均可自定义。 <!-- lang: js --> // jQuery Alert Dialogs Plugin // // Version 1.1 // // Cory S.N.
