:has()S2C Home « Selectors « :has()
Has Element selector.
Shorthand version $(':has(selector)')
Description
The :has() selector, selects elements containing at least one element matching the specified selector.
- The selector can appear in the specified element and/or descendants thereof.
- If this selector is not preceded by another selector, the universal selector ("*") is implied and so the whole DOM will be searched. Use another selector as in the examples below to narrow the search and improve performance.
- The same results can be achieved with better performance using
$("cssSelector").has(selector/DOMElement).
