scrollto - Jquery SlideToggle AND scroll -

-

i'm having problem slidetoggle link appears @ bottom of page. want user click show/hide hidden div (which works fine)

the problem page doesn't scroll down show now, not hidden div

as jquery novice, there way toggle div , center on page? or @ least scroll down, without things getting complicated?

thanks

to perform function, i'd recommend using callback slidetoggle call set document scroll using scrolltop function. you'll able determine value scrolltop setter using offset top position of toggled container relative page. i'd suggest restricting scroll behavior fire when element shown, not hidden.

in general, directly setting page scroll can jarring ux. reason i'm going give code animates scrolltop rather straight sets using scrolltop function, approach not necessary direct call scrolltop equally position page. think user i'd rather see gradual scroll rather sudden positional change.

the code, instance, take form:

$(".myshowhidelink").click(function() {     $(".mytogglecontainer").slidetoggle("slow", function() {         if ($(this).is(":visible")) {             $(document).animate({                 scrolltop: $(this).offset().top             }, "slow")         }     }); });

you may want use $(this).offset().top - 50 or similar scroll's set few pixels above top of container, that's you. find don't elements butting against top border of window.

i apologize haven't created test case i'm shooting hip, if doesn't work advertised, let me know , i'll adjust code.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
