js格式化当前时间

function currTime(){
var date = new Date();
var Y = date.getFullYear() + '-';
var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
var D = (date.getDate() < 10 ? '0' + date.getDate() : date.getDate()) + '-';
var h = (date.getHour() < 10 ? '0' + date.getHour() : date.getHour()) + '-';
var m = (date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()) + '-';
var s = (date.getSeconds() < 10 ? '0' + date.getSeconds(): date.getSeconds()) + '-';
retur Y + M + D + h + m + s;
}
