How to Dynamically Update iframe src with JavaScript Using Correct Syntax?

Changing iframe src with Javascript

When developing interactive web applications, it is often necessary to change the source (src) attribute of an iframe when users interact with the page. This allows for dynamic loading of different content into the iframe based on user input or preferences. However, it is important to use the correct syntax and event handlers to ensure that the iframe src is updated properly.

In the provided code example, the issue lies in the incorrect use of brackets in the JavaScript function that attempts to change the iframe's src. The line document.getElementById['calendar'].src = loc; should be modified to use the correct syntax for accessing element by id: document.getElementById('calendar').src = loc;.

With this correction, the code will now function as intended, allowing the iframe src to be changed when the user selects one of the radio buttons. Here's the corrected code for reference:

<code class="html"><script>
  function go(loc) {
    document.getElementById('calendar').src = loc;
  }
</script></code>
