javascript - 在javascript中将字符串分割两次

Question

我正在尝试将这个原始字符串分解为新行，其中 UPDATE(每个 #1234 的更新应该与新行中的每个 #1234 一起位于新行中，作为示例可以更好地理解:

#1234 23:28:13 sesedsr id 235768 end_log_pos 4347687 CRC32 0xfe136bd2 Query thread_id=1425356 exec_time=0 error_code=0 UPDATE sys_stat SET `sys_updated_by` = 'system', `sys_mod_count` = 19014, `sys_updated_on` = '2019-04-30 06:28:13', `type` = 'warning', `value` = ' running: xyzz' WHERE sys_status.`sys_id` = '2c5d43134f0262cf5210c712' /* nsdkjsnda1, gs:glide.scheduler.worker.0, tx:649346ba4f052cf5210c774 */--#1234 23:28:13 sedsdr id 608695768 end_log_pos 4350401 CRC32 0xcf3a7672 Query thread_id=1425363 exec_time=0 error_code=0 UPDATE sys_trig SET `sys_updated_by` = 'system', `sys_mod_count` = 4263170, `state` = 1, `sys_updated_on` = '2019-04-30 06:28:13' WHERE sys_trigger.`sys_id` = '64a31111f933130017c49d4d19eedeb6' /* ndaassdasdev02_1, gs:glide.scheduler.worker.0, tx:649346ba0899d62cf5210c774 */--#1234 23:28:13 ssder id 608695768 end_log_pos 4357673 CRC32 0x80dd6e55 Query thread_id=1425359 exec_time=0 error_code=0 UPDATE syseve SET `state` = 'resumed.2c9346ba4f9d62cf5210c774', `claimed_by` = 'appdsa32.sedassd.abcd.com:nas1' WHERE (sysevent0004.`process_on` <= '2019-04-30 06:28:13' AND sysevent0004.`state` = 'encore-ready' AND sysevent0004.`queue` = 'flow_engine') /* nsfsdfs1, gs:glide.scheduler.worker.0, tx:649346ba4f05f740899d62cf5210c774 */--#1234 23:28:13 ssader id 608695768 end_log_pos 4358824 CRC32 0xf281abf6 Query thread_id=1425365 exec_time=0 error_code=0 UPDATE syseve SET `state` = 'queued.2c9346ba4f05f740899d62cf5210c774', `claimed_by` = 'apdasda121.sesadasd.sbcd-ffd.com:ndasdasv02_1' WHERE (sysevent0004.`process_on` <= '2019-04-30 06:28:13' AND sysevent0004.`state` = 'ready' AND sysevent0004.`queue` = 'flow_engine') /* nsdfs2_1, gs:glide.scheduler.worker.0, tx:649346ba4f05f5210c774 */--UPDATE sys_trigger SET `log` = 0, `trigger_type` = 1, `sys_mod_count` = 4263171, `sys_updated_on` = '2019-04-30 06:28:13', `error_count` = 0, `priority` = 100, `trigger_class` = 'com.snc.process_flow.engine.PFJob', `job_context` = '#Mon Apr 29 23:28:13 PDT 2019 ', `run_count` = 1421121, `sys_id` = '64a31111f93313edeb6', `sys_updated_by` = 'system', `sys_created_on` = '2018-08-07 11:38:16', `job_id` = '88d87a408f3222037bdeeb5', `repeat` = '1970-01-01 00:00:16', `processing_duration` = 58, `name` = 'Flow Engine Event Handler', `next_action` = '2019-04-30 06:28:24', `state` = 0, `maintenance` = 0, `sys_created_by` = 'guest', `upgrade_safe` = 1, `claimed_by`= NULL WHERE sys_trigger.`sys_id` = '64a349d4d19eedeb6' /* nsadsfd02_1, gs:glide.scheduler.worker.0, tx:649346ba9d62cf5210c774 */

看起来像:

我已经用(“--”)将原始字符串拆分一次并将其分成单独的行。 另外:#1234 -> 可以是动态的 (#abcd)

Answer 1

您可以使用前瞻和交替对#1234 或UPDATE 进行拆分

(?=#1234)|(?=UPDATE)
