Window: frames property

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

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";
}
