jstl 자바스크립트 db 데이터

jstl로 보여주는 데이터 값을 

가지고 자바스크립트 함수를 타서

함수에서 데이터값을 받아서 db데이터를 수정하려고 한다..

근데 어렵네..

실행은 안됐지만 이리저리 해보던 소스

function btnresume_open_yn(){

  //open_yn

alert("1");

var form = document.resumeUploadForm;

var row = document.resumeUploadForm.open_yn.value;

var row2 = row;

alert(row2);

<c:set value="${data.resume_open_yn}" var = "open_yn"/> 

  

$('#searchDay1').val(open_yn);

 

  <c:if test="${data.resume_open_yn eq 'Y'}">                              

   <c:out value="${data.resume_open_yn}"/>

   </c:if>

   <c:if test="${data.resume_open_yn eq 'N'}">                              

   <c:out value="${data.resume_open_yn}"/>

   </c:if>

  //form.submit();

  

    alert("/////////");

  

  <c:set var="gender" value="${data.resume_open_yn}" />

  <c:choose>

  <c:when test="${gender eq 'Y'}">

  alert(gender);

  alert("1");

  </c:when>

  alert(gender);

  alert("2");

  </c:when>

  <c:otherwise>

 //  <c:set value="${data.resume_open_yn}" var = "open_yn"/> 

}

<c:if test="${data.resume_open_yn eq 'Y'}">
