Throttling: There must be a time interval between two successful adjacent calls. If there is no time interval or the time does not match the custom time, the call is invalid
Usage:
Const timeStart const dt = date.now () if(dt-this.timestart > 500){this.doajax () this.timestart = dt}else{ Console. log(' current timestamp is ',dt,' less than 500ms since last execution, not executed ') return}Copy the code
