javascript - How to track form submission in IE with bootstrap modal window? -

i have form user fills out , gets submitted through jquery using $("form").submit();

while form submitted use modal window twitter bootstrap library disable entire screen , tell user form being submitted.

my problem when form submit complete, pdf file downloaded client's machine response cases,
if case, user approves download , form stuck modal window covering entire page , idiot, because user can't go on using web page.

i've tried using $("form").submit() ".success()" function, when use that, jquery fails , page ceases function.

the thing can think of that's useful fact progress bar @ bottom of browser in ie runs , closes when pdf file download request pops up.

is there anyway can intercept progress of form submission, , close modal window @ moment when form done submitting?

please help

i had same issue few weeks , this solution helped. have redirect user page handle downloading of pdf.
