How come onclick doesn't reload iframe?

As a senior JavaScript developer, I have been tasked with finding a suitable way to reload an <iframe> using JavaScript. Although I have come across a method that involves setting the src attribute of the iframe to itself, it may not be the most elegant solution. Do you have any suggestions for a cleaner approach?

Yes, you can use the location.reload() method to reload the contents of an </b> element using JavaScript. Here's an example: </div></span><span><pre><code class="javascript">var iframe = document.getElementById('your-iframe-id'); iframe.contentWindow.location.reload(true);</code></pre></span><span><div class="mt-2"> In this example, we first select the <b><iframe></b> element using its ID. Then, we access its <b>contentWindow</b> property to get its window object, and call the <b>location.reload()</b> method on it to reload the contents of the iframe. The optional boolean parameter <b>true</b> is used to force a reload from the server instead of the cache.</div></span></div></div></div></div></main>;</div><script id="__NEXT_DATA__" type="application/json">{"props":{"pageProps":{"trpcState":{"json":{"mutations":[],"queries":[{"state":{"data":{"id":"clh8anhgc00eago82ayj5xhhr","originalId":"76167663","title":"How come onclick doesn't reload iframe?","content":"\u003cp\u003eAs a senior JavaScript developer, I have been tasked with finding a suitable way to reload an \u003ccode\u003e\u0026lt;iframe\u0026gt;\u003c/code\u003e using JavaScript.

Accepted Answer

Yes, there are several ways to reload an iframe using JavaScript. One way is to set the src attribute of the iframe to itself. This can be done by calling iframe.contentWindow.location.reload(); after getting the iframe with getElementById. Another way is to reset the src attribute with a time stamp for cache busting like this: iframe.src = iframe.src.split(\"?\")[0] + \"?_=\" + new Date().getTime();. A third way is to clear the src when query strings option is not possible (Data URI) like this:

var wasSrc = iframe.src;
iframe.onload = function () {
    iframe.onload = undefined;
    iframe.src = wasSrc;
}

I hope this helps! Let me know if you have any other questions.
