How to slow down window.location.href on AJAX request

You can use a timeout, and window.location.reload():

setTimeout(function() {
    window.location.reload();
}, 1000); // Time in milliseconds

Note: you cant call it like setTimeout(window.location.reload, 1000) because you will get an Illegal invocation error.

You may use settimeout to handle timing problem.

$(".closeMan").change(function () {
  if ($(this).prop("checked")) {
    setTimeout(function(){   
       $.ajax({
        type: "POST",
        url: "./close_man.php",
        success: function (result) {
         window.location.href = window.location.href;
        },
       });
      }
     }, 1000);
});

Simply use setTimeout (if you really need to slow down your application...):

$(".closeMan").change(function () {
  if ($(this).prop("checked")) {
    setTimeout(() => {
      $.ajax({
        type: "POST",
        url: "./close_man.php",
        success: () => {
          window.location.href = window.location.href;
        },
      });
    }, 500);
  }
});
