javascript submit not working in https.

javascript code

function apply() {     document.fileinfo.action='<%=uploadjsp%>';     // uploadjsp = https://localhost/upload.jsp     document.fileinfo.submit(); } 

html code

<form name="fileinfo" action="upload.jsp" enctype="multipart/form-data" method="post"> ... </form> 

result of newtwork capture on ie developer tool,

... domcontentloaded (event)‎‎  + 184ms -    load (event)‎‎  + 197ms - 

on load(event) break

this code working on http (uploadjsp = http://loaclhost/upload.jsp)

i don't know wrong.
please advice me solve problem

firstly, have tried printing value of document.fileinfo.action in first snippet after has been assigned = "<%=uploadjsp%>"?

<%= {code} %> processed when server sends html documents, if script in separate file html, or server doesn't process code in between <script> tags, document.fileinfo.action = "<%=uploadjsp%>" instead of document.fileinfo.action = "https://localhost/upload.jsp" intended.

second, don't need set action form again in javascript since it's set in html. so, instead of worrying how can pass correct value in first snippet, suggest removing document.fileinfo.action = "<%=uploadjsp%>" line altogether.
