Recently, I have been using Bard quite a lot because it has proven to be quite helpful. This time it was so much better than searching Google and DuckDuckGo that I decided to share it in a post for everybody’s reference.
When the URL of an iframe is changed within the iframe, the iframe element’s “src” attribute does not change. What is the reasoning for this?
There are a few reasons why the iframe element’s src attribute does not change when the URL of an iframe is changed within the iframe.
First, it is important to remember that an iframe is a separate document from the parent document. When you change the URL of an iframe within the iframe, you are actually changing the URL of the embedded document, not the iframe element itself.
Second, the src attribute of an iframe element is read-only. This means that once the src attribute is set, it cannot be changed.
Finally, there is a security risk associated with allowing iframes to change their own src attribute. If an iframe were able to change its own src attribute, it could potentially load malicious content from a different domain.
To avoid these problems, if you need to change the URL of an iframe, you must do so from the parent document. You can do this using JavaScript to set the src attribute of the iframe element.
Here is an example of how to change the URL of an iframe using JavaScript:
// Get the iframe element
var iframe = document.getElementById('myIframe');
// Set the src attribute of the iframe element
iframe.src = 'https://new-url.com';
When you set the src attribute of an iframe element using JavaScript, the iframe will be reloaded with the new URL.
It is important to note that you can only change the URL of an iframe if the iframe is from the same domain as the parent document. If the iframe is from a different domain, you will need to use a cross-origin resource sharing (CORS) request to change the URL of the iframe.
