html - How to change angular ng-init attributewith jquery -


so, have div image want change gif when specific scroll has occurred...

here html:

    <div class="col-xs-6 mitad" ng-init="varname='images/estandar/impresoraestandaranimada.gif'" id="seccion3b">         <img ng-src="{{varname}}" id="gif">     </div>

now, idea is, change url in varname... tried didn't work:

if ($(window).width() > 1700 && vistaestandar.scrolltop > 1596 && vistaestandar.scrolltop < 2490)        {             lore: 'url(../images/estandar/monitorveloz1.gif)';             $("#gif").attr("ng-src", "{{lore}}");         }

any idea how make work?? don't understand angular (new @ programming) , if try change without angular replacing src attribute img tag, gif loads first time if enter again in if condition or if refresh website, loads static image

updated:

all js code inside controller already:

app.controller('estandarctrl', function ($scope, $rootscope, $routeparams, $location, $http, data)  {   $(document).ready(function(){     // ----clases para mantener los colores del header     $(".navbar-header").addclass("fondoheader");     $("#fondomenu").addclass("fondoheader");     $("#footer").removeclass("esconder");     $("#social").removeclass("esconder");     $(".navbar-brand").removeclass("esconder");     $("#botonvideo").removeclass("fondoboton");     $("#vista").removeclass("barravista");       // ----propiedades para los scrollbar     var vistaestandar = document.getelementbyid('vista');     vistaestandar.style.overflow= "auto";     vistaestandar.style.overflowx= "hidden";     vistaestandar.style.height = 100 + "%";     $("#vista").smoothwheel();     // ---animaciones para diferentes resoluciones     vistaestandar.onscroll = function() {animacionesestandarvista()};     function animacionesestandarvista()      {          if (($(window).width() > 1700 && vistaestandar.scrolltop > 1596 && vistaestandar.scrolltop < 2490) || ($(window).width() > 1700 && document.documentelement.scrolltop > 1596 && document.documentelement.scrolltop < 2490)){            }         else if (($(window).width() > 1700 && vistaestandar.scrolltop > 3888 && vistaestandar.scrolltop < 4286) || ($(window).width() > 1700 && document.documentelement.scrolltop > 3888 && document.documentelement.scrolltop < 4286)) {             document.getelementbyid("section6").style.background = "url(images/estandar/monitorestandarentrada.gif)";             document.getelementbyid("section6").style.backgroundsize = "cover";             document.getelementbyid("section6").style.backgroundposition = "bottom";          }         else if (($(window).width() > 1700 && vistaestandar.scrolltop > 4450) || ($(window).width() > 1700 && document.documentelement.scrolltop > 4450)) {              document.getelementbyid("section6").style.background = "url(images/estandar/monitorestandarsalida.gif)";             document.getelementbyid("section6").style.backgroundsize = "cover";             document.getelementbyid("section6").style.backgroundposition = "bottom";             }         else         {          }   }); });

so have controller partial

on html element aka scroll use ngchange directive , pass function change url variable:

html:

<!-- change scrollable element whatever scroll bar on aka table... ect --> <div>     <scrollable-element ng-change="mychangefunction()"></scrollable-element> </div>

js:

// inside controller: $scope.mychangefunction = function() {         var newurl = '/some/image.img'         $scope.varname = newurl;     };
