jQuery Alert Dialogs,又一个基于jQuery的提示框插件,主要包括Alert、Confirm、prompt这三种,还有一个高级范例,可以在提示框内嵌入HTML语言,可以自定义风格样式。jQuery的提示框插件有很多种,每一款都是出自不同的高人之手,因此都比较有自己的特点,包括风格和使用方法等。

这个Jquery插件的目的是替代JavaScript的标准函数alert(),confirm(),和 prompt()。这个插件有如下这些特点:
1:这个插件可以使你可以支持你自己的css制定。使你的网站看起来更专业。
2:允许你自定义对话框的标题。
3:在IE7中,可以使你避免使用JavaScript 的prompt()函数带来的页面重新加载。
4:这些方法都模拟了Windows的模式对话框。在你改变改变浏览器窗口大小时候,它能够自适应用户
窗口的调整。
5:如果你引入了jQuery UI Draggable plugin插件,那这个插件也可以被自由拖动。
