html - Change images on hover with AngularJS -


okay, need change images on hover in angular app. however, due peculiarities of site, wasn't feasible change images on hover via css [without ton of work], have been best way, realize.

so instead, i'm using ng-mouseenter , ng-mouseleave change images on hover.

landing.jade

img.share-button(src='images/btn_share.png', ng-click='dropdownshareicons()')                 img.share-icon-top(src='{{ shareicons[0].orig }}', data-id='0', ng-mouseenter='colorizeicons($event)', ng-mouseleave='decolorizeicons($event)')                 img.share-icon-top(src='{{ shareicons[1].orig }}', data-id='1', ng-mouseenter='colorizeicons($event)', ng-mouseleave='decolorizeicons($event)')                 img.share-icon-top(src='{{ shareicons[2].orig }}', data-id='2', ng-mouseenter='colorizeicons($event)', ng-mouseleave='decolorizeicons($event)')

then in controller have object contains paths images, , functions switch images on hover.

landing.js

$scope.shareicons = [         {orig: 'images/follow_weibo_grey.png', hover: 'images/follow_weibo_colored.png'},         {orig: 'images/follow_wechat_grey.png', hover: 'images/follow_wechat_colored.png'},         {orig: 'images/follow_youku_grey.png', hover: 'images/follow_youku_colored.png'},         ]       $scope.colorizeicons = function($event) {         $event.target.src = $scope.shareicons[$event.target.dataset.id].hover;     }      $scope.decolorizeicons = function($event) {         $event.target.src = $scope.shareicons[$event.target.dataset.id].orig;     }

this works fine , on local environment, on production server veeeerrrrry slow. like, 2-3 seconds switch images.

so question - there easy way fix this? either within angular or workaround/hack. doesnt matter long image switch time sped bit. or going continue slow long i'm switching images via js this? ideally, avoid rewriting using css.

thanks in advance.

hey bro had same problem, , think of doing preloading images. helped alot. add small piece of js code loads asynchronously @ beginning of document. example: 

var images = new array()   function preload() {     (i = 0; < preload.arguments.length; i++) {       images[i] = new image()       images[i].src = preload.arguments[i]     }   }   preload(     // (i = 0; < $scope.members.length; ++){     //   return members[i].source + ",";     // }     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image1.1.jpg",     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image2.1.jpg",     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image3.1.jpg",     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image4.1.jpg",     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image5.1.jpg",     "http://ramiawar.co/pages/speakerspage/pages/team/assets/images/image6.1.jpg"   )

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
