JS loop li adds click event (application of closure)

Without further ado, I will post the code directly for you. The specific code is as follows:

var aLi = document.querySelectorAll('.article-tab li');
 for (var i = 0; i <= aLi.length; i++) {  
 (function(){  
  var p = i  
  aLi[i].onclick = function() {  
   alert(p);  
  }
 })();
}

The above is the JS loop li adding click introduced by the editor. Event (Application of Closure), I hope it will be helpful to everyone. If you have any questions, please leave me a message and the editor will reply to you in time.
