angularjs - Angular JS conditional logic to check "class name" exists -

-

below angular js code works fine on mouseover & mouseout. need regard adding conditional logic on js code.

if class name "active" exists, img src path have in "overimg" if user mouseover & mouseout. but, present behaviour removes overimg once user mouseout element. active state have different rest of navigation element.

angularjs:

.directive('elehoveraction', function() { return {     link: function (scope, elem, attrs) {         var imgobj = $(elem).find('img');         var upimg = attrs.eleupimgsrc;         var overimg = attrs.eleoverimgsrc;          elem.bind('mouseover', function () {             $(imgobj).attr("src", overimg);             scope.$apply();         });         elem.bind('mouseout', function() {             $(imgobj).attr("src", upimg);             scope.$apply();         });     }   };                 });

html:

 <li class="menu-item menu-item--category active" ele-hover-action ele-up-img-src="images/test1.png" ele-over-img-src="images/test1-over.png">    <a href="#"><img src="images/test1.png" oversrc="images/test1-over.png"  alt=""/><span>test1</span></a> </li> <li class="menu-item menu-item--category" ele-hover-action ele-up-img-src="images/test2.png" ele-over-img-src="images/test2-over.png">   <a href="#"><img src="images/test2.png" oversrc="images/test2-over.png"  alt=""/><span>test2</span></a> </li>

the obvious method add if statement "mouseout" handler checks if element hasclass active:

.directive('elehoveraction', function() { return {     link: function (scope, elem, attrs) {         var imgobj = elem.find('img');         var upimg = attrs.eleupimgsrc;         var overimg = attrs.eleoverimgsrc;          elem.bind('mouseover', function () {             imgobj.attr("src", overimg);             scope.$apply();         });         elem.bind('mouseout', function() {             if (!elem.hasclass("active")) {                 imgobj.attr("src", upimg);             }             scope.$apply();         });          if (elem.hasclass("active")) {             imgobj.attr("src", overimg);         } else {             imgobj.attr("src", upimg);         }     }   };                 });

i went ahead , set src attribute of image based on directive attributes. take part out if don't want it. also, wrapping elem in jquery call redundant because angular elements wrapped in either jquery (if available when angular loads) or own jqlite. otherwise, wouldn't able call elem.bind.

try in fiddle.

[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.. /...
