Creating DOM Elements from HTML Strings
In JavaScript, there are instances when you need to convert HTML strings into their corresponding DOM elements. This is a fundamental operation for dynamically creating and manipulating the page's content, such as when appending elements to the document.
To accomplish this task, you can utilize a DOMParser. The syntax for using DOMParser is:
const doc = new DOMParser().parseFromString(htmlString, "text/xml");
Here, htmlString represents the HTML code you wish to convert, and doc is the resulting document containing the parsed DOM elements.
For instance, consider the following HTML string:
<div> <a href="#"></a> <span></span> </div>
Using the DOMParser, you can convert this string into a DOM element as follows:
const htmlString = ""; const doc = new DOMParser().parseFromString(htmlString, "text/xml");
The doc object now holds the parsed HTML as a DOM element, which can be appended to the page using methods like appendChild():
const parentElement = document.getElementById('parent'); parentElement.appendChild(doc.firstChild);
This will add the parsed HTML content as a child element of the parentElement in the actual DOM. Note that DOMParser interprets XHTML-style HTML, which requires closing tags, as in the example above.
