html - How to get the reference of an opened window with target blank -

i'm trying reference javascript of window it's open after clicking anchor has target _blank.

like this:

<a href="..." target="_blank"> new window </a> 

so can check if later if window closed.

hope guys can help.

html

<a href="..." target="_blank" id="my-link"> new window </a> 

javascript

var link = document.getelementbyid('my-link');  link.onclick = function() {     var reference = window.open(link.href, '_blank');     return false; } 

see it!

if wanted links target="_blank", should succeed in selecting them.

var alllinks = document.getelementsbytagname('a'),     blanklinks = [];  (var = 0, linkslength = alllinks.length; < linkslength; i++) {      if (alllinks[i].getattribute('target') === '_blank') {         blanklinks.push(alllinks[i]);     }  } 

on fresh browser...

var blanklinks = document.queryselectorall('a[target="_blank"]);
