【jQuery/Selector #45】:not() Selector

1Q74 2023. 3. 14. 00:37

1. Description

jQuery(":not(selector)") : selector와 매치되지 않는 Element를 찾는다.
.not()메소드를 사용하는 것이 :not()필터에 selector를 나열하는 것보다 읽기 쉽고, 대부분의 경우 좋은 선택이 된다고 합니다.

2. Example

#1버튼을 클릭하면 <tr>태그의 1번 인덱스와 매칭되지 않는 <tr>태그를 찾아서 배경색을 변경한다. 버튼을 클릭할 때마다 스타일이 토글된다.
