How to loop through nested iframes?

To loop through nested iframes in a webpage, you can use a recursive function that can handle the nesting of iframes at different levels. Here is an example code snippet in JavaScript that demonstrates how you can loop through nested iframes:

function loopThroughFrames(window) {
    // Loop through each iframe in the current window
    for (let i = 0; i < window.frames.length; i++) {
        const frame = window.frames[i];
        
        // If the current frame has nested iframes
        if (frame.frames.length > 0) {
            // Recursive call to loop through nested iframes
            loopThroughFrames(frame);
        } else {
            // Perform some action on the iframe, for example accessing its document
            console.log(frame.document);
        }
    }
}

// Call the function with the top most window as the starting point
loopThroughFrames(window);

In this code snippet, the loopThroughFrames function takes a window object as an argument and loops through each iframe in that window. If a frame has nested iframes, it makes a recursive call to the function to loop through those nested iframes as well. Finally, it performs some action on each iframe, such as accessing its document.

By using this recursive approach, you can effectively loop through nested iframes in a webpage and perform actions on them as needed.
