使用js 加載下面代碼，通過getDateDiff(時間戳)來調用js 方法得到具體的時間格式
var minute = 1000 * 60;
var hour = minute * 60;
var day = hour * 24;
var halfamonth = day * 15;
var month = day * 30;
function getDateDiff(dateTimeStamp){
var now = new Date().getTime();
var diffValue = now - dateTimeStamp;
if(diffValue < 0){
//若日期不符則彈出窗口告之
//alert("結束日期不能小于開始日期！");
}
var monthC =diffValue/month;
var weekC =diffValue/(7*day);
var dayC =diffValue/day;
var hourC =diffValue/hour;
var minC =diffValue/minute;
if(monthC>=1){
result=parseInt(monthC) + "個月前";
}
else if(weekC>=1){
result=parseInt(weekC) + "周前";
}
else if(dayC>=1){
result=parseInt(dayC) +"天前";
}
else if(hourC>=1){
result=parseInt(hourC) +"個小時前";
}
else if(minC>=1){
result=parseInt(minC) +"分鐘前";
}else
result="剛剛";
return result;
}
