今天帮朋友做个网站,发现了一个很好用的日期控件,如图:

calendar控件

用法也相当简单,方法如下:

1.在网页中嵌入一个IFRAME和一段SCRIPT.

<IFRAME frameBorder=0 id=popFrame name=popFrame scrolling=no src="Calendar.htm" style="BORDER-BOTTOM: 2px ridge; BORDER-LEFT: 2px ridge; BORDER-RIGHT: 2px ridge; BORDER-TOP: 2px ridge; POSITION: absolute; VISIBILITY: hidden; Z-INDEX: 65535"></IFRAME>
<SCRIPT>document.onclick=function() {document.getElementById("popFrame").style.visibility="hidden";}</SCRIPT>

2.插入一个窗体,其中包含一个文本框和一个按钮,注意按钮的类型(button),在按钮中插入单击事件.

3.OK,大功告成.

附控件代码如下,把代码存为Calendar.htm文件就可以了.
