js返回日期串（如：yyyyMMddHHmmSS）

		/**
 * 格式化日期
 * @param date
 * @returns {String}
 */
function formatDateToString(date){
	if(checkIsNull(date)){
		date = new Date();
	}
	var year = date.getFullYear();
	var month = date.getMonth()+1;
	var day = date.getDate();
	if(month<10) month = "0"+month;
	if(day<10) day = "0"+day;
	return year+month+day;
}
function formateDateAndTimeToString(date)
{
	var hours = date.getHours();
	var mins = date.getMinutes();
	var secs = date.getSeconds();
	var msecs = date.getMilliseconds();
	if(hours<10) hours = "0"+hours;
	if(mins<10) mins = "0"+mins;
	if(secs<10) secs = "0"+secs;
	if(msecs<10) secs = "0"+msecs;
	return formatDateToString(date)+hours+mins+secs+msecs;
}

直接从页面调用

formateDateAndTimeToString（new Date()）

方法就行。
