1Q74 2023. 3. 5. 18:05

1. Description

jQuery(":lang(language)") : language코드가 설정된 Element를 찾는다. 
1. language코드 + '-'(하이픈)이 따라오는 Element도 같이 찾는다.
    ex) :lang(en)은 :lang(en-us)도 포함하여 찾는다.

2. Example

#1, #3버튼을 클릭하면 해당 laguage코드의 <td>배경색을 변경한다. 버튼을 클릭할 때마 스타일이 토글된다.

 

#2를 클릭하면 <div name="_1q74-example-1">의 하위Element 배경색이 변경된다.

:lang(language)앞에 태그(예지에서는 <td>)가 생략되면 <html lang="ko">를 인식한다.
