javascript - ng-switch not reacting to dynamic value change -


i new , experimenting angularjs.

that being said, unsure how bind value ng-switch , change between views dynamically changing 'activeview' variable value.

side note: practice switch between views this? views different ways of displaying same data pretty same context , did not see reason create different page 2 views. oh , views contents directives components.

the html:

<body ng-controller="somecontroller vm">     <div ng-switch="{{vm.activeview}}">         <div ng-switch-when="someview">             directive component         </div>          <div ng-switch-when="anotherview">             directive component         </div>          <div ng-switch-default>             nothing show         </div>     </div> </body>

the controller:

(function () { 'use strict';  angular     .module('app')     .controller('somecontroller', somecontroller);  function somecontroller() {     var vm = this;      vm.activeview = '';      function setviewtype(viewtype) {         vm.viewtypes = viewtype;     }      setviewtype('anotherview'); } })();

so happen default switch visible, event after calling setviewtype('anotherview');

thanks in advance!

  1. you don't need interpolation when using ng-switch ({{vm.activeview}}).
  2. you aren't assigning vm.activeview value.

  3. your angular.module doesn't have dependency array. if place define module add it.

    (function () { 'use strict';  angular.module('app', []) // add dependency array     .controller('somecontroller', somecontroller);  function somecontroller() {     var vm = this;      vm.activeview = 'anotherview'; // change      function setviewtype(viewtype) {         vm.viewtypes = viewtype;     }      setviewtype('anotherview'); // changes viewtypes prop } })();

check on jsfiddle.
