To preload an iframe, you can use the "prefetch" attribute in the HTML link tag. This tells the browser to start downloading the content for the specified URL in the background, so that it is ready to be loaded in an iframe when it is needed.
Here is an example of how you can use the prefetch attribute to preload an iframe:
1 2 3 4 5 6 7 8 9 10 11 |
<!DOCTYPE html> <html> <head> <title>Preload iframe</title> <link rel="prefetch" href="https://example.com/iframe-content.html" as="document"> </head> <body> <h1>Preloading iframe</h1> <iframe src="https://example.com/iframe-content.html" frameborder="0"></iframe> </body> </html> |
In this example, the link tag is used to prefetch the content of the iframe by specifying the URL of the iframe content in the href attribute. The as="document" attribute tells the browser to prefetch the content as a document. Make sure to replace "https://example.com/iframe-content.html" with the actual URL of the iframe content.
By prefetching the iframe content, the browser will start downloading it in the background while the main page is loading. This helps to reduce the delay when the iframe is later inserted into the page, as the content will already be available in the browser's cache.
