Window: frames property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Returns the window itself, which is an array-like object, listing the direct sub-frames of the current window.

Value

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.
  • Each item in the 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).
  • For more details about the returned value, refer to this thread on mozilla.dev.platform.

Examples

js
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";
}
