javascript - Validate Multiple Email Addresses with HTML5 -


i'm trying construct email form takes multiple comma separated emails input , verifies them using html5. want use following regex sanity check input:

\b[a-za-z0-9._%+-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}\b

here's i've tried

this doesn't seem work more one:

<input type="email" pattern="\b[a-za-z0-9._%+-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}\b" value="" multiple>

this works, built in email validation, seems .+@.+.

<input type="email" value="" multiple>

is there way mix pattern , multiple regex checks each item in comma separated list?

i have demo here: http://codepen.io/ben336/pen/ihjka

try this:

<input type="email" multiple pattern="^([\w+-.%]+@[\w-.]+\.[a-za-z]{2,4},*[\w]*)+$" value="">

update:

using <input type="email" value="" multiple> seem bugged letting "a@b" pass. though go method keep semantics said, , use validation on server side in case tries submit email "a@b".

just note, should validate on server side security reasons anyway, client side validation can bypassed easily.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
