can't access source object when window.postMessage in Edge
I made a test with the following code sample and it can work well in Edge:
Page1.html:
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8" /> <script> function openChild() { var childwin = window.open('Page2.html', 'popup', 'height=300px, width=500px'); } window.addEventListener("message", (event) => { let txt = document.querySelector('#txtMsg'); txt.value = `Name is ${event.data.pName} Age is ${event.data.pAge}`; console.log(event.source); //update: get event.source }); </script></head><body> <form> <fieldset> <input type='button' id='btnopen' value='Open child' onclick='openChild();' /> <input type='text' id='txtMsg' /> </fieldset> </form></body></html>Page2.html:
<!DOCTYPE html><html><head> <title></title> <meta charset="utf-8" /> <script> function sendMessage() { let msg = { pName: "Bob", pAge: "35" }; window.opener.postMessage(msg, 'http://domain_name/Page1.html') window.opener.focus(); } </script></head><body> <form> <fieldset> <input type='button' id='btnSendMsg' value='Send Message' onclick='sendMessage();' /> </fieldset> </form></body></html>Result:
You could refer to the sample, if still not working, please provide a minimal sample which can reproduce the issue. With only the above code you provide, I can't reproduce the issue.
