//将日期格式化为“yyyymmdd”样式
function formatDate(date){
var year = date.getFullYear();
var month = "0" + (date.getMonth() + 1).toString();
month = month.slice(month.length -2);
var day = "0" + date.getDate();
day = day.slice(day.length - 2);
var dateStr = year + month + day;
return dateStr;
}

//将日期格式化为“hh24:mi:ss”的样式
function formatTime(date){
var hours = date.getHours();
var minutes = "0" + date.getMinutes();
minutes = minutes.slice(minutes.length - 2);
var seconds = "0" + date.getSeconds();
seconds = seconds.slice(seconds.length - 2);
var timeStr = hours + ":" + minutes + ":" + seconds;
return timeStr;
}

//将日期格式化为“YYYYMMDDhhmmss”
function formatDateTime(date){
var year = date.getFullYear();
var month = fillZero((date.getMonth()+ 1).toString());
var day = fillZero(date.getDate());
var hour = fillZero(date.getHours());
var minute = fillZero(date.getMinutes());
var second = fillZero(date.getSeconds());
var dateStr = year + month +day+hour+minute+second;
return dateStr;

//在数字前面补“0”
function fillZero(value){
var fullValue = "0" + value;
fullValue = fullValue.slice(fullValue.length - 2);
return fullValue;
}
}
