The insertAdjacentHTML
method is a powerful DOM method that allows you to dynamically add new content to a web page. It provides a flexible and convenient way to insert HTML content wherever you need it on the page.
To use insertAdjacentHTML
, you need to invoke it on a specific DOM element and provide two parameters: the position where the content should be inserted, and a string that contains the HTML content you want to add.
Here’s an example:
const item = `<div>
test
</div>
`
document.querySelector('#container').insertAdjacentHTML('afterend', item)
In the above example, the position is set to 'afterend'
. This means that the new HTML content will be added after the #container
element.
There are four possible positions you can use with insertAdjacentHTML
:
beforebegin
: Inserts the content before the specified element.afterbegin
: Inserts the content as the first child of the specified element.beforeend
: Inserts the content as the last child of the specified element.afterend
: Inserts the content after the specified element.
Let’s say you want to add a new item to an existing list. You can achieve this by using insertAdjacentHTML
as follows:
document.querySelector('ul').insertAdjacentHTML('beforeend', '<li>item</li>')
In the above example, the new <li>
element containing the text “item” will be added as the last child of the <ul>
element.
Using insertAdjacentHTML
allows you to dynamically manipulate the content of your web pages and provide a better user experience. Experiment with the different positions and make your website more interactive!
