Is this a bug in jQuery Iframe code or expected behaviour? -

-

in jquery way access iframe 

$("#myiframe").contents();

say wanted "#mydiv" "#myiframe", use

$("#myiframe").contents().find("#mydiv");

in code i've been writing had 

var $savequery = $("#myiframe").contents().find("#mydiv"); var $innerquery = $savequery.find("#myinnerdiv");

did not work. using debugger inspected $savequery object. innerhtml always

"                         "

even when looking @ filled content on screen. after hair pulling changed , did work

var $savequery = $("#myiframe").contents().find("#mydiv"); var $innerquery = $("#myiframe").contents().find("#myinnerdiv");

is bug or expected behavior? i'm using version 2.2.0

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.
