如何在 JavaScript 中有效率地重新載入 Iframe？

Efficient Iframe Reloading in JavaScript

Reloading an iframe within a web page can be a useful task in various scenarios. One common approach is to assign the iframe's src attribute to itself, but this method may appear inelegant.

To tackle this issue and provide a cleaner solution, we can utilize the following approach:

document.getElementById('some_frame_id').contentWindow.location.reload();

This JavaScript code snippet effectively reloads the iframe with the specified ID. It accesses the iframe's content window and calls the reload() method on its location object.

It's important to note that in certain browsers, such as Firefox, accessing window.frames[] by ID may not be possible. Instead, indexing by name or index should be used for compatibility across different browsers.
