How can I send an event from parent window to its child window?

I want to send some event/data from parent window to its child window. How can I do so?

I have tried postMessage, but it didn’t work.

  1. It has worked now, earlier I was doing some syntax mistake. Here is the correct code for the same.

    //parent Window
    childWindow=window.open("http:/localhost/abcd.php","_blank","width=500,height=500");
    childWindow.postMessage('message',"http://localhost:80/child.php");
    
    
    //child Window
    var newUrl='';
    window.addEventListener(
     "message",
     function(e) { 
    
    console.log(e.data);//your data is captured in e.data 
    }, false);
