Returns the window itself, which is an array-like object, listing the direct sub-frames of the current window.
A list of frame objects. It is similar to an array in that it has a length property and its items can be accessed using the [i] notation.
frames === window evaluates to true.window.frames pseudo-array represents the Window object corresponding to the given <frame>'s or <iframe>'s content, not the frame or iframe DOM element (i.e., window.frames[0] is the same thing as document.getElementsByTagName("iframe")[0].contentWindow).const frames = window.frames; // or const frames = window.parent.frames;
for (let i = 0; i < frames.length; i++) {
// do something with each subframe as frames[i]
frames[i].document.body.style.background = "red";
}
