Javascript format date and time function _ time and date

The following js functions format the date. The functions are written in one row, so you can directly take charge of the application. The Code is as follows:

Function DateUtil () {}/*** function: Format time * example: DateUtil. format ("yyyy/MM/dd", "Thu Nov 9 20:30:37 UTC + 0800 2006"); * return value: 2006/11/09 */DateUtil. format = function (fmtCode, date) {var result, d, arr_d; var patrn_now_1 =/^ y {4}-M {2}-d {2} \ sh {2}: m {2}: s {2} $ /; var patrn_now_11 =/^ y {4}-M {1, 2}-d {1, 2} \ sh {1, 2}: m {1}: s {1, 2} $ /; var patrn_now_2 =/^ y {4} \/M {2} \/d {2} \ sh {2}: m {2}: s {2} $ /; var patrn_now_22 =/^ y {4} \/M {1, 2} \/d {1, 2} \ sh {1, 2}: m {1, 2 }: S {1, 2} $ /; var patrn_now_3 =/^ y {4} M {2} d {2} sh {2} m {2} s {2} s $ /; var patrn_now_33 =/^ y {4} year M {1, 2} d {1, 2} sh {1, 2} hour m {1, 2} minute s {1, 2} seconds $ /; var patrn_date_1 =/^ y {4}-M {2}-d {2} $ /; var patrn_date_11 =/^ y {4}-M {1, 2}-d {1, 2} $ /; var patrn_date_2 =/^ y {4} \/M {2} \/d {2} $ /; var patrn_date_22 =/^ y {4} \/M {1, 2} \/d {1, 2} $ /; var patrn_date_3 =/^ y {4}-M {2}-d {2} $ /; var patrn_date_33 =/^ y {4} year M {1, 2} d {1, 2} $/; var patrn_time_1 =/^ h {2}: m {2}: S {2} $/; var patrn_time_11 =/^ h {1, 2}: m {1, 2}: s {1, 2} $ /; var patrn_time_2 =/^ h {2} m {2} minute s {2} seconds $ /; var patrn_time_22 =/^ h {1, 2} m {1, 2} minute s {1, 2} seconds $/; if (!
