ASP.NET中为TextBox中添加calendar.js示例代码

  1.在工程文件下面新建文件夹"js",然后向其中添加JavaScript.js新建项,重命名为calendar.js。

  2.向calendar.js中写入代码,

  

复制代码 代码如下:

  var cal;

  var isFocus=false; //是否为焦点

  //function SelectDate(obj,strFormat) //两个参数改为只传一个

  function SelectDate(obj)

  {

  var date = new Date();

  var by = date.getFullYear()-80; //最小值 → 80 年前

  var ey = date.getFullYear()+20; //最大值 → 20 年后

  cal = (cal==null) ? new Calendar(by, ey, 0) : cal; //初始化为中文版,1为英文版

  //cal.dateFormatStyle = strFormat; // 默认显示格式为:yyyy-MM-dd ,还可显示 yyyy/MM/dd

  cal.show(obj);

  }

  /**//* 返回日期 */

  String.prototype.toDate = function(style){

  var y = this.substring(style.indexOf('y'),style.lastIndexOf('y')+1);//年

  var m = this.substring(style.indexOf('M'),style.lastIndexOf('M')+1);//月

  var d = this.substring(style.indexOf('d'),style.lastIndexOf('d')+1);//日

  if(isNaN(y)) y = new Date().getFullYear();

  if(isNaN(m)) m = new Date().getMonth();

  if(isNaN(d)) d = new Date().getDate();

  var dt ;

  eval ("dt = new Date('"+ y+"', '"+(m-1)+"','"+ d +"')");

  return dt;

  }

  /**//* 格式化日期 */

  Date.prototype.format = function(style){

  var o = {

  "M+" : this.getMonth() + 1, //month

  "d+" : this.getDate(), //day

  "h+" : this.getHours(), //hour

  "m+" : this.getMinutes(), //minute

  "s+" : this.getSeconds(), //second

  "w+" : "天一二三四五六".charAt(this.getDay()), //week

  "q+" : Math.floor((this.getMonth() + 3) / 3), //quarter

  "S" : this.getMilliseconds() //millisecond

  }

  if(/(y+)/.test(style)){

  style = style.replace(RegExp.$1,

  (this.getFullYear() + "").substr(4 - RegExp.$1.length));

  }

  for(var k in o){

  if(new RegExp("("+ k +")").test(style)){

  style = style.replace(RegExp.$1,

  RegExp.$1.length == 1 ? o[k] :

  ("00" + o[k]).substr(("" + o[k]).length));

  }

  }

  return style;

  };

  }

  document.write('</div>');

  3.保存文件后,即完成了js日历控件的编写。

  4.在相应需要日历控件的源处写在head标签下面写

  

复制代码 代码如下:

  <script type="text/javascript" src="../js/calendar.js"></script>

  其中,src是你JavaScript的位置

  5.所有填写日期的TextBox,加这两个属性:ReadOnly="True" onclick="SelectDate(this)"
