Js frontend determines whether the start time is earlier than the end time

Copy codeThe Code is as follows:
// Determine whether the start time is earlier than the end time
If ($ ("# txtBeginTime"). length> 0 & $ ("# txtEndTime"). length> 0 ){
If (Date. parse (TimeFormatToSQL ($ ("# txtBeginTime "). val ()). replace ("-", "/")> Date. parse (TimeFormatToSQL ($ ("# txtEndTime "). val ()). replace ("-","/"))){
Alert ("the start time cannot be later than the end time! ");
// $ ("# TxtBeginSearchTimeByBE"). focus ();
Return;
