用js封装的时间设置器

文章出处：作者：　发布时间：2005-04-24

js的成员和方法好象没有private和public之分，列一下public的成员和方法

成员：
name 控件的名字，既这个控件的变量名（必选）
fName 时间的input的name，可以后台获取，也就是input的name属性（可选，默认为 m_input

方法：
play() 使时间框呈现动态效果
getTime() 获取设定的时间

IE5.5+效果最佳，IE5运行也没有问题，就是css有些对不齐（IE5实在是太老了。。。可以退休了）
运行代码框

<style type="text/css">
body {
	background-color: #D4D0C8;
}
.m_frameborder {
	border-left: 2px inset #D4D0C8;
	border-top: 2px inset #D4D0C8;
	border-right: 2px inset #FFFFFF;
	border-bottom: 2px inset #FFFFFF;
	width: 100px;
	height: 19px;
	background-color: #FFFFFF;
	overflow: hidden;
	text-align: right;
	font-family: "Tahoma";
	font-size: 10px;
}
.m_arrow {
	width: 16px;
	height: 8px;
	font-family: "Webdings";
	font-size: 7px;
	line-height: 2px;
	padding-left: 2px;
	cursor: default;
}
.m_input {
	width: 18px;
	height: 14px;
	border: 0px solid black;
	font-family: "Tahoma";
	font-size: 9px;
	text-align: right;
}
</style>
