change variable only for one ng-repeat document angularjs -


i'm trying show more text when user clicks read more button:

<md-content class="md-padding" layout-xs="column" layout="row" layout-wrap>   <div flex-xs flex-gt-xs="50" layout="column" ng-repeat="paquete in paquetes">     <md-card>       <md-card-title layout="row" layout-xs="column">         <md-card-title-media layout-margin>           <img ng-src="{{paquete.img}}" class="md-card-image margin-auto" alt="image caption">         </md-card-title-media>         <md-card-title-text>           <span class="md-headline blue">{{paquete.title}}</span>           <span class="md-subhead dark-blue">{{paquete.desc | limitto: limit.limit}}              <span class="threedots" ng-show="mas.mas">... </span>              <span style="cursor: pointer;" class="blue underlined"                  ng-click="limitfunction(paquete.desc)">leer                     <span class="mas" ng-show="mas.mas">más</span>                    <span class="menos" ng-show="menos.menos">menos</span>.              </span>           </span>         </md-card-title-text>       </md-card-title>     </md-card>   </div>     </md-content>

i'm limiting initial descripction {{paquete.desc | limitto: limit.limit}} , letting user click read more ng-click="limitfunction(paquete.desc)"

my controller:

$scope.limit = {limit: 200};  $scope.limitfunction = function (desc) {     $scope.limit.limit = desc.length; };

but when click on 1 of ng-repeat elements, $scope.limit changes of them instead of 1 i'm clicking.

how change $scope.limit 1 i'm clicking?

you put limit on paquete object , pass limit function

 <span class="md-subhead dark-blue">{{paquete.desc | limitto: paquete.limit}}<span class="threedots" ng-show="mas.mas">... </span><span style="cursor: pointer;" class="blue underlined" ng-click="limitfunction(paquete)">leer <span class="mas" ng-show="mas.mas">más</span><span class="menos" ng-show="menos.menos">menos</span>.</span></span>

in controller:

$scope.limitfunction = function (paquete) {     paquete.limit = paquete.desc.length; };
