Changing iframe src using JavaScript: Troubleshooting

You are having an issue with changing the src attribute of an iframe when a radio button is clicked. To rectify this problem, it's essential to examine your code to identify the exact cause. One plausible issue is the incorrect use of brackets.

In your code, the line:

<code class="javascript">document.getElementById['calendar'].src = loc;</code>

is likely causing the issue. The correct syntax should be:

<code class="javascript">document.getElementById('calendar').src = loc;</code>

In JavaScript, to retrieve an element using getElementById(), you need to pass a string parameter within single quotes, not brackets. By using the correct syntax, you can ensure that the JavaScript code correctly identifies the iframe by its id and updates its src attribute accordingly.
