检测关闭窗口事件功能

Question

我想编写一个JavaScript，使::当我将鼠标移到关闭的窗口和选项卡上时，它仅应在当时给我警报。我已经编写了该脚本，但是每当我将鼠标移到“最小化”，“向下还原”，“关闭”或将鼠标悬停在选项卡上时，该脚本就会执行。我希望逻辑仅在将鼠标悬停在关闭的窗口和选项卡上时执行。每当我将鼠标悬停在关闭的窗口/选项卡上时，都不应重复该操作。

<style>
  .banner-text>div>.banner-link.link-highlight
  {
     display: none;
  }

.booking-widget-home 
    {
  background-image:url('https://www.chimp.in/content/dam/chimp/website/banner/target/12/upgrade-banner.jpg') !important;
  }

 .banner-title 
 {
color: white;
    }

.banner-description 
{
color: white;
   } 

  .banner-link.link-highlight
  {

    border-radius: 10px;
  }

  .banner-text > p > span 
  {
    bottom: -20px;
    position: relative;
  }

   div.knowMore
{
display: block;
}

</style>
<script>

(function()
{
     'use strict';
      var cnt=6000;
      function init() 
      {
          if(typeof jQuery !="undefined")
          {         
            windowClose();  
           }
          else
          {
              cnt=cnt-500;
              if(cnt>500)setTimeout(init,500);
          }
      }


      var addEvent = function(obj, evt, fn) 
      {
    if (obj.addEventListener) 
    {
        obj.addEventListener(evt, fn, false);
    }
    else if (obj.attachEvent) 
    {
        obj.attachEvent("on" + evt, fn);
    }
    };

addEvent(document, "mouseout", function(event) 
{
    event = event ? event : window.event;
    var from = event.relatedTarget || event.toElement;
    if ( (!from || from.nodeName == "HTML") && event.clientY <= 100 ) 
    {

    alert("Please Browse through website before exit!");
    }
});                                      


function windowClose()
{

    some other logic ....
}
 init();
})()
</script>
