javascript - window.postMessage internet explorer 11 support -

i attempting use postmessage() send data new window spawned parent window. postmessage() works fine in chrome/firefox internet explorer seems choking on addeventlistener , no data being sent new page.

i understand ie should use attachevent have implemented, child page supports addeventlistener, parent page not while referencing child.

parent:

var newtab = window.open('community_printerfriendlyeligibility'); if (newtab.addeventlistener) {      console.log('add1');      newtab.addeventlistener('load', function() {          console.log('add2');          newtab.postmessage(data,'*');      });   } else if (newtab.attachevent) {      console.log('attach1');      newtab.attachevent('load', function() {          console.log('attach2');          newtab.postmessage(data,'*');      });  } 

child:

if (window.addeventlistener) {     console.log('add');     window.addeventlistener('message', function(event) {          //process chrome     }, false); } else if (window.attachevent) {     console.log('attach');     window.attachevent('message', function(event) {          //process ie      });  }   

debug in ie:

parent window:     attach1  child window:     add 

debug in chrome:

parent window:     add1     add2  child window:     add 

so in ie, parent reference child window not have addeventlistener child window accepts addeventlistener

afaik it's not needed in ie11: http://caniuse.com/#search=addeventlistener

just tested in ie11 , can confirm uses addeventlistener.

are emulating ie8 in parent page? use attach.

the new window revert default (edge), use add.
