}扩充：
1、时间格式化2(与当前相差一天 就按格式的类型显示，否则就 显示为 "13小时前" 或 "35分钟前"等)
/**
* 时间格式化2
*
* @param strDateTime:需要格式化的字符串时间
* @param intType： 格式化类型
*
* @return string 与当前相差一天 就按格式的类型显示，否则就 显示为 "13小时前" 或 "35分钟前"等
*/
function formatDateTime2(strDateTime, intType){
if(strDateTime != null && strDateTime != ''){
var timeDiff = getTimediff(strDateTime,new Date());
if(timeDiff != null && timeDiff.length == 4){
if(timeDiff[0] > 0 || timeDiff[1] > 24)
return formatDateTime(strDateTime, intType);
else{
if(timeDiff[1] > 0)
return timeDiff[1] + "小时前";
else if(timeDiff[2] > 0)
return timeDiff[2] + "分钟前";
else
return timeDiff[3] + "秒前";
}
}else return '';
}else
return '';
}2、根据字符串日期 获取 js Date 类型
/**
* 根据字符串日期 获取 js Date 类型
* @param strDateTime
*/
function getJSDateFormString(strDateTime){
var newDate, arrDate = new Array(), arrTime = new Array();
if(strDateTime != null && strDateTime != ""){
//获取日期和时间数组
if (strDateTime.toString().indexOf("-") != -1) {
var item = strDateTime.split(" ");
arrDate = item[0].toString().split("-");
arrTime = item[1].toString().split(":");
} else if (strDateTime.toString().indexOf("/") != -1) {
var item = strDateTime.split(" ");
arrDate = item[0].toString().split("/");
arrTime = item[1].toString().split(":");
} else if (!isNaN(Number(strDateTime))) {
//unix 时间戳
newDate = new Date(Number(strDateTime) * 1000);
return newDate;
}
//处理数据
if (arrDate != undefined && arrTime != undefined && arrDate.length == 3 && arrTime.length == 3 && (newDate == undefined || newDate == null)) {
newDate = new Date(
parseInt(arrDate[0]),
parseInt(Number(arrDate[1]) - 1),
parseInt(arrDate[2]),
parseInt(arrTime[0]),
parseInt(arrTime[1]),
parseInt(arrTime[2])
);
return newDate;
}
}else
return null;
}3、获取两时间差
/**
* 获取两时间差
* @param beginDate
* @param endDate
*
* @return array() / null
*/
function getTimediff(beginDate,endDate){
if(beginDate != null && beginDate != '' && endDate != null && endDate != ''){
beginDate = typeof(beginDate) == "string"?getJSDateFormString(beginDate):beginDate;
endDate = typeof(endDate) == "string"?getJSDateFormString(endDate):endDate;
if(beginDate != null && endDate != null){
beginDate = Math.round(beginDate.getTime() / 1000); //转换为 unix 时间戳
endDate = Math.round(endDate.getTime() / 1000); //转换为 unix 时间戳
var timediff = Math.abs(endDate - beginDate);
var remain = timediff % 86400;
var hours = parseInt(remain / 3600);
remain = remain % 3600;
var mins = parseInt(remain / 60);
var secs = remain % 60;
return [
parseInt(timediff/86400), // day
hours, // hour
mins, // min
secs // sec
];
}else
return null;
}else
return null;
