title: var myvalue = window.opener.document.getElementById(“parentId1”) is not working
body: <p>I was trying to get the value from my child.jsp to my parent.jsp using </p>
  
  <pre><code>var myvalue = window.opener.document.getElementById(“parentId1”) 
  </code></pre>
  
  <p>Even though there were no errors found in the console the value is not getting in the parent page.</p>
  
  <p>The child popup window has the url starting like, <code>https://host.example.com:7001/...</code>.. and the parent page url is different starts with <code>http://anotherhost:8080/webapp</code>.... is there any issue in communicating with a child window and a parent page which is on another server?</p>
  
  <p>If so how can I solve this issue?</p>
