   var date = new Date(+new Date()+8*3600*1000).toISOString().replace(/T/g,' ').replace(/\.[\d]{3}Z/,'');
   console.log(date);//2017-01-22 11:08:46

   var date = new Date();
   var strDate = date.toLocaleString().replace(/[年月]/g,'-').replace(/[日上下午]/g,'');
   console.log(strDate);//  2017/1/22 11:11:56

		   function getNowFormatDate() {
    			var date = new Date();
			    var seperator1 = "-";
			    var seperator2 = ":";
			    var month = date.getMonth() + 1;
			   
			    var strDate = date.getDate();
			    if (month >= 1 && month <= 9) {
			        month = "0" + month;
			    }
			    if (strDate >= 0 && strDate <= 9) {
			        strDate = "0" + strDate;
			    }
			    
			    var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
			            + " " + date.getHours() + seperator2 + date.getMinutes()
			            + seperator2 + date.getSeconds();
			    return currentdate;
			} 
			var data = getNowFormatDate();
			console.log(data);  //2017-01-22 11:14:16
