兼容FireFox的js日历支持时间的获取

网络编程 JavaScript 网页特效 时间日期 分类:[default] 更新日期: 2015-12-14
应网友要求,花了五六个小时,为我经常用的 js 日历添加时间的获取。
代码如下:

var cal;
var isFocus=false; //是否为焦点
var pickMode ={
"second":1,
"minute":2,
"hour":3,
"day":4,
"month":5,
"year":6 };
var topY=0,leftX=0; //自定义定位偏移量 2007-02-11 由 寒羽枫添加
//选择日期 → 由 寒羽枫 2007-06-10 添加,通过 ID 来选日期
function SelectDateById(id,strFormat,x,y)
{
    var obj = document.getElementById(id);
    if(obj == null){return false;}
    obj.focus();
    if(obj.onclick != null){obj.onclick();}
    else if(obj.click != null){obj.click();}
    else{SelectDate(obj,strFormat,x,y)}
}
//选择日期 → 由 寒羽枫 2006-06-25 添加
function SelectDate(obj,strFormat,x,y)
{
    leftX =(x == null) ? leftX : x;
    topY =(y == null) ? topY : y;//自定义定位偏移量 2007-02-11 由 寒羽枫添加    
    if(document.getElementById("ContainerPanel")==null){InitContainerPanel();}
var date = new Date();
var by = date.getFullYear()-50; //最小值 → 50 年前
var ey = date.getFullYear()+50; //最大值 → 50 年后
//cal = new Calendar(by, ey,1,strFormat); //初始化英文版,0 为中文版
cal = (cal==null) ? new Calendar(by, ey, 0) : cal; //不用每次都初始化 2006-12-03 修正
cal.DateMode =pickMode["second"]; //复位
if(strFormat.indexOf('s')< 0) {cal.DateMode =pickMode["minute"];}//精度为分
if(strFormat.indexOf('m')< 0) {cal.DateMode =pickMode["hour"];}//精度为时
if(strFormat.indexOf('h')< 0) {cal.DateMode =pickMode["day"];}//精度为日
if(strFormat.indexOf('d')< 0) {cal.DateMode =pickMode["month"];}//精度为月
if(strFormat.indexOf('M')< 0) {cal.DateMode =pickMode["year"];}//精度为年
if(strFormat.indexOf('y')< 0) {cal.DateMode =pickMode["second"];}//默认精度为秒
cal.dateFormatStyleOld = cal.dateFormatStyle;
cal.dateFormatStyle = strFormat;
cal.show(obj);
}

将上述代码另存为 WebCalendar.js,页面调用代码
代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head >
        <script src="WebCalendar.js" type="text/javascript"></script>
</head>
<body>
<form name="form1" method="post" action="WebForm1.aspx" >
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy 年')" readonly="true" style="width:265px;cursor:pointer" /><br />
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy 年 MM 月')" readonly="true" style="width:265px;cursor:pointer" /><br />
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy\/MM\/dd')" readonly="true" style="width:265px;cursor:pointer" /><br />
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy-MM-dd hh时')" readonly="true" style="width:265px;cursor:pointer" /><br />
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy-MM-dd hh:mm')" readonly="true" style="width:265px;cursor:pointer" /><br />
<input type="text" value="" maxlength="100" onclick="SelectDate(this,'yyyy年MM月dd日 hh时mm分ss秒',0,-150)" readonly="true" style="width:265px;cursor:pointer" /><br />
</form>
</body>
</html>

调用方法:
1、传入对象:SelectDate(this,'yyyy 年')
2、传入 ID:SelectDateById('Txt_CreateDateST01','yyyy 年')
3、参数 SelectDate(this,'yyyy 年',0,-150)
格式(注意大小写):yyyy→年,MM→月,dd→天,hh→24小时制,mm→分钟,ss→秒
0 → 相对于文本框的横向偏移量
-150 → 相对于文本框的纵向偏移量
