A label specifies a rectangular area within the content where the browser can display different documents with scroll bars and borders. To embed another document within the current HTML document, use inline frames. A reference to an element can be specified using the HTMLiframe name attribute. In JavaScript, references to elements are also made using the name attribute. An iframe is essentially used to display a web page within the currently displayed web page. The URL of the document containing the iframe is specified using the "src" attribute.

Detailed introduction: 1. Network delay. When the browser loads a web page containing an iframe, it needs to send a request to the server to obtain the content in the iframe. If the network delay is high, the time to obtain the content will increase, resulting in slow loading of the iframe. ; 2. When the resource loading time is long, the size of the resource is large or the server response time is long, the loading speed will be more obviously slower; 3. Loading sequence, etc.</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/599101.html" title="What does data-id in iframe mean?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/202308/28/2023082814252193959.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="What does data-id in iframe mean?" /> </a> <a href="https://www.php.cn/faq/599101.html" title="What does data-id in iframe mean?" class="phphistorical_Version2_mids_title">What does data-id in iframe mean?</a> <span class="Articlelist_txts_time">Aug 28, 2023 pm 02:25 PM</span> <p class="Articlelist_txts_p">The data-id in an iframe refers to a custom attribute used in HTML tags to store the identifier of a specific element. By using the data-id attribute, you can add a unique identifier to the iframe element so that it can be manipulated and accessed in JavaScript. The naming of the data-id attribute can be customized according to specific needs, but some naming conventions are usually followed to ensure its uniqueness and readability.

This issue has now been widely reported by users who have discovered "TokenFactoryIframe" files that Outlook downloads on every visit. Outlook downloads this mysterious file every few seconds or at least every time you access Outlook on Apple platforms. Based on our findings, this appears to be an issue caused by an incorrect server-side update posted to Outlook and has nothing to do with Safari or macOS.
