javascript - Remove "checked" from radio when a checkbox is unchecked -

-

i have checkbox (#fbmngch) reveals set of radio buttons (name=admanage) when clicked. when checkbox unclicked, radio button selected still remains checked. have checked status of radio button removed once checkbox unchecked.

this being used in form, if user changes mind selecting service, details service wiped (so value of selected radio not end in php , email). hope makes sense.

i have given considerable time , not seeming work correctly. last set of if-statements part of code wrote. not sure if missing something, selecting wrong, or what. highly appreciated. thanks!

html

<li>     <input type="checkbox" class="cbox" name="fbchecks[]" value="facebook ad mgmt" id="fbmngch">     <label for="test">facebook ad management</label>     <ul id="fbmnglist">         <li>             <input type="radio" name="admanage" value="ad management 1" id="adman1">             <label for="adman1">ad fund - 1</label>         </li>         <li>             <input type="radio" name="admanage" value="ad management 2" id="adman2">             <label for="adman2">ad fund - 2</label>         </li>         <li>             <input type="radio" name="admanage" value="ad management 3" id="adman3">             <label for="adman3">ad fund - 3</label>         </li>         <li>             <input type="radio" name="admanage" value="ad management 4" id="adman4">             <label for="adman4">ad fund - 4</label>         </li>         <div id="fbaderror" class="accterror"></div>     </ul> </li>

js

$fbmngch = $("#fbmngch"); $fbmnglist = $("#fbmnglist");  //hide fb management list $fbmnglist.hide();  //on fb management select $fbmngch.click(function() {     //toggle fb management list     $fbmnglist.toggle(); });  $fbadvalid = false; $fbaderror = $("#fbaderror");  //if fb ad management checked if ($fbmngch.attr('checked')) function validatefb() {    $("input[name=admanage]").each(function () {   //loopingthroughradiobuttons     // "this" current element(radio) in loop       if ($(this).is(':checked')) {             $fbadvalid = true; //radio button checked);       }        if ($fbadvalid.attr = true ) {             $fbaderror.empty();       }    }); }; if ($fbmngch.blur($fbadvalid.attr = false)) {     $fbaderror.append("<li> please select facebook ad plan. </li>");     //appends error document }    if ($fbmngch.blur($fbmngch.not('checked'))) {     $("input[name=admanage]").each(function () {         if ($(this).is(':checked')) {             $("input[name=admanage]").removeattr('checked');         }     });     //remove checks radios };   $("input[name=admanage]").click(validatefb);

maybe not understanding requirements, can't test in checkbox event routine , uncheck checked radio button:

$fbmngch.click(function () {     //toggle fb management list     $fbmnglist.toggle();     if (!$fbmnglist.attr('checked')) {         $fbmnglist.find('input:checked').attr('checked', false);     } });

[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.. /...
