用于辅助输入的Calendar [2005-8-30]
Xmercy 发表在 Plus

很矛盾，现在能满足大部分要求，但有些常用的用法不支持，要支持的话代码量很变得很可观，现在是值不值的问题了

主要代码：

//region Method
	display		:
		function(o, e, d){
			with(Calendar){
				o = typeof(o) == "object" ? o : document.getElementById(o);
				if(window.event){
					curPosX = document.body.scrollLeft + event.x;
					curPosY = document.body.scrollTop + event.y;
				} else{
					curPosX = e.pageX;
					curPosY = e.pageY;
				}
				if(o.value == "" && d) o.value = d;
				with(document.getElementById("Calendar__")){
					if(o != curCapture) {
						curCapture = o;
						if(style.display == "block"){
							style.left = curPosX + "px";
							style.top = curPosY + "px";
						}
						else load();
					}
					else{
						if (style.display == "block") style.display = "none";
						else load();
					} 
				}
			}
		},
	load			:
		function(){
			with(Calendar){
				curDay = loadDate(curCapture.value);
				with(curDay){
					year = getFullYear();
					month = getMonth() + 1;
					date = 	getDate();
				}
				init();
			}
		},
	init			:
		function(){
			with(Calendar){
				with(new Date(year, month-1, date)){
					year = getFullYear();
					month = getMonth() + 1;
					date = 	 getDate();
					setDate(1);
					var first = getDay();
					setMonth(getMonth()+1, 0)
					paint(first, getDate());
				}
			}
		},
	paint			:
		function(first, last){
			var calendar = document.getElementById("Calendar__");
			var grid = document.getElementById("dataGrid__");
			var i, l;
			l = Math.ceil((first + last)/7);
			if(!document.all){
				calendar.style.height = (41 + 19 * Math.ceil((first + last)/7)) + "px";
			}
			grid.innerHTML = new Array(l*7 + 1).join("<li><a></a></li>");
			with(Calendar){
				var strDate = "{0}-{1}".Format(year, month);
				var isTodayMonth = ((year == today.getFullYear()) && (month == today.getMonth() + 1));
				var isCurdayMonth = ((year == curDay.getFullYear()) && (month == curDay.getMonth() + 1));
				var todayDate = today.getDate();
				for(i=0;i<last;i++){
					grid.childNodes[first + i].innerHTML = '<a href="{2}-{1}"{0} onclick="Calendar.setValue({1});return false">{1}</a>'.Format(((i+1) == todayDate && isTodayMonth) ? ' class="today"' : isCurdayMonth && (i+1) == curDay.getDate()?' class="curDay"':'', i + 1, strDate);
				}
				document.getElementById("dateText__").innerHTML = '<a href="' + (year-1) + '年" onclick="Calendar.turn(-12);return false" title="上一年">&lt;&lt;</a>&nbsp;<a href="上一月" onclick="Calendar.turn(-1);return false" title="上一月">&lt;</a>&nbsp;' + year + " - " + month + '&nbsp;<a href="下一月" onclick="Calendar.turn(1);return false" title="下一月">&gt;</a>&nbsp;<a href="' + (year+1) + '年" onclick="Calendar.turn(12);return false" title="下一年">&gt;&gt;</a>';
				with(calendar){
					style.left = Calendar.curPosX + "px";
					style.top = Calendar.curPosY + "px";
					style.display = "block";
				}
			}
		},
	turn			:
		function(num){
			Calendar.month +=  num;
			Calendar.date = 1;
			Calendar.init();
		},
	setValue		:
		function(val){

				document.getElementById("Calendar__").style.display = "none";

		},
	loadDate		:
		function(op, formatString){
			formatString = formatString || "ymd";
			var m, year, month, day;
			switch(formatString){
				case "ymd" :
					m = op.match(new RegExp("^((\\d{4})|(\\d{2}))([-./])(\\d{1,2})\\4(\\d{1,2}){ListLog}quot;));
					if(m == null ) return new Date();
					day = m[6];
					month = m[5]*1;
					year =  (m[2].length == 4) ? m[2] : GetFullYear(parseInt(m[3], 10));
					break;
