javascript - Visual studio 12 and regular expressions error -


i getting strange error in vs2012.

i've got following script:

<script type="text/javascript">      function validateemail($email) {         var emailreg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;         if( !emailreg.test( $email ) ) {             return false;         } else {             return true;         }     }  </script>

this throws sot of errors in ide, , in vs2010 used run ok.

what wrong?

thanks!

let me guess... using razor (a cshtml page)? if so, problem caused because ide thinks part @([\w-]+\.) razor expression , then, javascript reg ex looking missing parenthesis. fix this, need escape @ using @@ code be:

<script type="text/javascript">      function validateemail($email) {         var emailreg = /^([\w-\.]+@@([\w-]+\.)+[\w-]{2,4})?$/;         if( !emailreg.test( $email ) ) {             return false;         } else {             return true;         }     }  </script>

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).
