To execute a command in an iframe of a popup, you can use the following steps:

  1. Get a reference to the popup window: When you open a popup window using JavaScript, you can store a reference to that window in a variable. For example:
1
var popup = window.open("popup.html", "Popup", "width=300,height=200");


  1. Get a reference to the iframe in the popup window: Once you have a reference to the popup window, you can access elements within that window, including iframes. You can use the contentWindow property of the iframe element to get the window object of the iframe. For example:
1
2
var iframe = popup.document.getElementById("iframeId");
var iframeWindow = iframe.contentWindow;


  1. Execute a command in the iframe: Now that you have a reference to the iframe window, you can execute commands within the iframe as you would in a normal window. For example, you can access elements within the iframe and manipulate them using JavaScript. For instance:
1
2
// Execute a command in the iframe
iframeWindow.document.getElementById("elementId").style.backgroundColor = "red";


By following these steps, you can execute commands in an iframe of a popup window using JavaScript.
