jQuery – Only child selector example
The “only-child” is used to select all elements that are the only child of their parent.
Examples
- $(‘:only-child’) – selects all elements that are the only child of their parent.
- $(‘li:only-child’) – selects all elements matched by <li> that are the only child of their parent.
jQuery Example
In this example, when the button is clicked, only the <li>DEF #1</li> will be match and change its background color dynamically, because it’s the only child of their parent.
