原生js获取当前时间

function getdate(){
	    const dt = new Date();
    	const y = dt.getFullYear();
    	const m = dt.getMonth() + 1;
    	const d = dt.getDate();
    	const hh = dt.getHours().toString().padStart(2, 0);
    	const mm = dt.getMinutes().toString().padStart(2, 0);
    	const ss = dt.getSeconds().toString().padStart(2, 0);
    	const time = y + '-' + m + '-' + d + ' ' + hh + ':' + mm + ':' + ss;
		return time;
}
console.log(getdate());
