:visible Selector
visible selector
version added: 1.0jQuery(':visible')
Description: Selects all elements that are visible.
Elements can be considered hidden for several reasons:
- They have a CSS
displayvalue ofnone. - They are form elements with
type="hidden". - Their width and height are explicitly set to 0.
- An ancestor element is hidden, so the element is not shown on the page.
Elements with visibility: hidden or opacity: 0 are considered to be visible, since they still consume space in the layout. During animations that hide an element, the element is considered to be visible until the end of the animation. During animations to show an element, the element is considered to be visible at the start at the animation.
How :visible is calculated was changed in jQuery 1.3.2. The release notes outline the changes in more detail.
Additional Notes:
- Because
:visibleis a jQuery extension and not part of the CSS specification, queries using:visiblecannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. To achieve the best performance when using:visibleto select elements, first select the elements using a pure CSS selector, then use.filter(":visible").
Example:
Make all visible divs turn yellow on click.
