Any suggestion How to make Iframe communicate to parent window. Scenario :

Inside Iframe there is separate website in same domain having multiple links. When user clicks on Link inside iframe the value should propagate to parent window.

I tried tracking the click event inside Iframe and getting iFrame.src but it didnt work.

HTML :

 <iframe #Iframe class="iframek" (click)="onChange(kIframe)" sandbox="allow-same-origin allow-scripts allow-top-navigation" id="iframe_k"   [src]='safeUrl' scrolling="auto" frameborder="0" allowfullscreen=true wmode="transparent" name="kiframe"></iframe>

onChange(iframe) {
  console.log("onchange");
  if(iframe.contentWindow)
  {
    console.log(iframe.contentWindow.document);
  }
  else{
    console.log(iframe.contentWindow);
  }
  
  console.log(iframe.getAttribute('src'));
  
}
