JavaScript实现日历

说明：时间的问题在开发十几种非常的实用 但处理很麻烦 下面提供一个简单但是 实用的方法！只是在页面通过调用下面的javaScript ！在数据库中的的数据类型可以申请为String的类型 调用和处理起来也就很方便 不用进行转换！、

效果图：

 

<script language="JavaScript">

String.prototype.Format = function(){
var tmpStr = this;
var iLen = arguments.length;
for(var i=0;i<iLen;i++){
   tmpStr = tmpStr.replace(new RegExp("\\{" + i + "\\}", "g"), arguments[i]);
}
return tmpStr;

</script>

 

调用方法：

 

<input type="text" size="30" name="inputTime" Readonly="true">
<input type="button" onclick="Calendar.display('inputTime', event)" value="选择日期">

 

也可以将上面代码保存在一个js文件里（保存时把开头和结尾的<script></script>标识代码去掉），比如：calendar.js，然后在网页中通过下面方式引入该文件的调用<script src="calendar.js"></script>，然后就可以在网页中调用了。
