• 函数封装

// 解析dateTime距离现在的时间
// dateTime的格式为2020-05-05 15:05:05
function getDateDiff(dateTime) 
	var dateTimeStamp = new Date(dateTime.replace(/-/g, '/')).getTime()
	var minute = 1000 * 60;
	var hour = minute * 60;
	var day = hour * 24;
	var halfamonth = day * 15;
	var month = day * 30;
	var now = new Date().getTime();
	var diffValue = now - dateTimeStamp;
	var result = '';
	if (diffValue < 0) 
		return;
	
	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) + "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) + "小时前";
	 else if (minC >= 1) 
		result = "" + parseInt(minC) + "分钟前";
	 else 
		result = "刚刚";
	
	console.log(`[info] $result`)
	return result
