								<p class="Articlelist_txts_p">Inline frames are called iframes in HTML. 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 &quot;src&quot; attribute. Syntax The following is the syntax of HTML &lt;iframesrc=&quot;URL&quot;title=&quot;d</p>

								<span class="Articlelist_txts_time">Aug 24, 2023 pm	 05:51 PM</span>
								<p class="Articlelist_txts_p">The reasons for slow loading of iframes mainly include network delay, long resource loading time, loading order, caching mechanism and security policy. 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>

								<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. The data-id attribute can also be used to identify and manipulate a specific iframe.</p>

Detailed introduction: 1. Ajax is a technology used to create dynamic web pages. It can realize asynchronous update of the page by exchanging data with the server in the background without refreshing the entire page. Using Ajax can load and display content more flexibly, and there is no need to use iframe to embed other pages; 2. JavaScript library or framework , such as React and so on.</p>
