json - MVC4 Jquery / UI / Ajax Release Build breaks my form submissions? -


very strange issue.

i have mvc4 web application uses pop-up editing (through jqueryui , partial views) , works fine when application built in debug mode, or if it's built in release mode , run on iis express.

the httppost action either returns html partialview containing errors (which repopulates ui dialog box) or json response return json(new { success = true });

if deploy debug build iis, works fine.

however, if deploy release build iis stops working , client browsers (all of them) start treating json responses file downloads......?!

i've fiddled requests , different..... ones work send headers:

accept: */* content-type: application/x-www-form-urlencoded; charset=utf-8 x-requested-with: xmlhttprequest

...and ones fail.....

accept: text/html, application/xhtml+xml, */* content-type: application/x-www-form-urlencoded

...and no x-requested-with header.

tbh i've got no idea why request headers different based on build config....?! help?

well found out answer was......talk perfect storm....

i using jquery 1.9.1. apparently recent versions of jquery cause "bundling" break.....

in debug mode, , in release mode on iis express bundling was't doing anything. however, when published release-mode iis sprung life.....and promptly broke javascript.

....which preventing jquery.on handler overriding form submit button.....

....which causing form submitted via html , not ajax......

....which causing json response "downloaded file" browser......

....which makes me feel bit dumb asking question in first place clues there.....

the solution, of course, fix jquery*.min.js files don't break bundling (as described in attached question/answer). ho hum.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
