js 获取当天日期/时间

const getDateTime = (type) => {
	// 获取当前日期
	let timestamp = Date.parse(new Date());
	let date = new Date(timestamp);
	if (type == \'tomorrow\') { // 明天
		date.setDate(date.getDate() + 1);

	} else if(type == \'today\') { // 今天
		date.setDate(date.getDate());
	}
	//获取年份  
	var Y = date.getFullYear();
	//获取月份  
	var M = (date.getMonth() + 1 < 10 ? \'0\' + (date.getMonth() + 1) : date.getMonth() + 1);
	//获取当日日期 
	var D = date.getDate() < 10 ? \'0\' + date.getDate() : date.getDate();
	let todayDate = Y + \'-\' + M + \'-\' + D;
	return todayDate
};

let time = getDateTime(\'today\')
console.log(time)
