Quick Reference
The window.frames property returns an array with all window objects in the window.
<!-- frames on our page -->
<iframe style="width:100%; height:100px;"></iframe> <!-- frame 0 -->
<iframe style="width:100%; height:100px;"></iframe> <!-- frame 1 -->
<iframe style="width:100%; height:100px;"></iframe> <!-- frame 2 -->
<iframe style="width:100%; height:100px;"></iframe> <!-- frame 3 -->
<iframe style="width:100%; height:100px;"></iframe> <!-- frame 4 -->The following gets all the page frames and places them in an array my_frames. Then we can refer to the frame in position 2 (counting from 0) and color it red.
// variable
let my_frames = window.frames;
// change color of frame 2
my_frames[2].document.body.style.background = '#ff0000';Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
Output
(no output, except that the frame in array position 2 is made red)Syntax
window.framesJavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
