누군가가 제공 할 수있는 도움에 정말 감사드립니다!JQuery에서 웹 서비스 호출이 실패합니다.
나는 웹 서비스에 대한 JQuery Ajax 호출을 설정하려고 시도 해왔다. 그리고 내가 해왔 던 작은 디버깅은 웹 서비스가 매개 변수를 반환하고 클라이언트 측에서 경고를 사용함을 보여준다. 함수는 데이터가 데이터 문자열로가는 것을 보여주기 위해 함수를 호출하지만, 매개 변수를 전혀 사용하지 않도록 변경했습니다. 여전히 작동하지 않습니다. 아무것도 일어나지 않고 아무것도 움직이지 않습니다. 나는 'url :'또는 'data :'항목에 어떤 유형의 구문 오류가있을 수 있는지 궁금합니다. 여러 가지 방법으로 예제를 살펴 보았 기 때문입니다.
AJAX 지원 웹 페이지를 사용하여 프로젝트를 설정합니다.
내가 전에 말했던 것처럼 - 도와주세요 !!

웹 설정이 아닌 문자열 JSON 객체를 반환하는 것 같습니다
