On the application of Ajaxprefilter in jquery _jquery

jquery defines an AJAX filter ajaxprefilter that filters the Ajax requests that are sent through jquery's corresponding Ajax functions.

In a project where there is a need to specify a start time, an end time to get a process line that has some value in the time range over time, we can define a generic ajaxprefilter to filter all AJAX requests, and when the start time exceeds the end time, The AJAX request is abort.

$.ajaxprefilter (function (options, originaloptions, jqxhr) {//tm1, tm2 indicates start time, end time Var requesttype, params, StartTime, E
  Ndtime; RequestType = (Originaloptions.type | | ""). toUpperCase (); Jsonp when type is undefined if (RequestType = = "Get") {params = Originaloptions.data? $.param (Originaloptions.data)
  : Originaloptions.url;
  else if (RequestType = = "POST") {params = $.param (Originaloptions.data); } if (params) {starttime = Params.match (/(^TM1|&TM1) = ([^&#]*)/i)? decodeURIComponent (Params.match (^tm1|&
    AMP;TM1) = ([^&#]*)/i) [2].replace (/\+/g, "%20")): null; Endtime = Params.match (/(^TM2|&TM2) = ([^&#]*)/i)?
    decodeURIComponent (Params.match (^TM2|&TM2) = ([^&#]*)/i) [2].replace (/\+/g, "%20")): null;
      if (starttime && endtime) {starttime = Starttime.replace (/\-/g, "/");
      Endtime = Endtime.replace (/\-/g, "/");
     if (new Date (starttime). GetTime () > New Date (endtime). GetTime ()) {jqxhr.abort ();   Alert ("Start time cannot be greater than end time"); }
    }
  }
});
