javascript - JSP JQuery show div after logout -

-

i have jsp website has menu bar. upon clicking logout button, page redirects welcome jsp page. however, hope make once user clicks logout, welcome page has div span reads "you have logged out". have been trying work, no avail.

in javascript, start globally defined variable, , have 2 related functions.

logoutdeterminant = "no";  function determine(word) {    if (word == "yes")    {        logoutdeterminant = "yes";        alert(logoutdeterminant);     } }  function showlogoutnotification() {    if (logoutdeterminant = "yes") {        alert(logoutdeterminant);        //toggle class    } }

the global variable logout determinant starts no. when welcome jsp loads, runs showlogoutnotification, means global variable assigned no, , class div on page not toggled. div successful logout notification, , there class hides it. toggle doesnt work, , hidden class isn't removed.

once user enters main page, , clicks logout, function determine("yes") runs on click, setting logoutdeterminant "yes".

now, when welcome page loads again, imagined would've registered logout determinant yes, , therefore toggled class. however, comes out no. leads me believe javascript resets when page changes, , logout determinant again "no".

how 1 go making logout notification on same welcome page? have access java via jsp servlets, jquery/javascript, html, , such.

pass message request parameter

string message = "logged out successfully"; response.sendredirect("mypage.jsp?message=" + urlencoder.encode(message, "utf-8"));

so can display in jsp follows

<span id="mymessage">${param.message}</span>

use javascript/jquery wisely hide message in few minutes,

settimeout(function() {     $('#mymessage').fadeout('fast'); }, 1000); // <-- time in milliseconds

you may use fadeout() or hide().

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
