js获取当地时间并且拼接时间格式的三种方式

    js获取当地时间并且拼接时间格式，在stackoverflow上有人在问，查了资料，各种方法将时间格式改成任意自己想要的样式。

    1.

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

    2.        

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

   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

   3.字符串拼接方式

  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

		   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</pre><br><br>            </div>
