 * 作者：顾燕兵
 * 版本：0.1.0
 *
 * 使用方法：
 * 1：普通方式，无任何限制
 * $("#id").calendar();
 *
 * 2：级联方式，结束日期大于开始日期
 * $("#startDate").calendar({
 onChange:function() {
 if ($("#startDate").val() == '') {
 $("#endDate").val('');
 } else {
 if ($.parseDate($("#startDate").val()).getTime() >= $.parseDate($("#endDate").val()).getTime() || ($.parseDate($("#startDate").val()).getTime() + 30 * 24 * 60 * 60 * 1000) < $.parseDate($("#endDate").val()).getTime()) {
 $("#endDate").val('');
 }

 if ($("#endDate").val() == '') {
 $("#endDate").focus();
 }
 }
 });

 $("#endDate").calendar({showClearButton:false,showTodayButton:false,prevDayFromInput:$("#startDate"),
 beginDateFn:function() {
 var date = $.parseDate($("#startDate").val());
 return new Date(date.getTime() + 24 * 60 * 60 * 1000);
 });
 *
 * 3：参数说明
 * calendarClass：自定义样式名
 * showPrevDay：（true/false）是否显示今天以前的日期，默认为“true”
 * readOnly：（true/false）编辑框是否只读，默认为“true”
 * showClearButton:（true/false）显示清除按钮，默认为“true”
 * showTodayButton:（true/false）显示今天按钮，默认为“true”
 * onChange:（function(){}）日期被改变时候，触发的事件
 * prevDayFromInput:日期从指定次文本框的内容开始
 * beginDateFn:获取开始日期的方法
 * endDateFn:获取结束日期的方法
 * isDisabledFn：调用此方法判断日期是否有效
