javascript - How to call a function on the scope from a string value -

i have object containing array of strings

$scope.actions=[     "add_inscription",     "add_tools",     "add_instruction",     "remove_inscription",     "remove_tools",     "remove_instruction" ]; 

and able dynamic action calls through delegating function..

$scope.delegate = function () {      var arg = arguments[0];      ( key in $scope.actions ) {          if ($scope.actions[key] == arg ) {              // call function has matching name          }     } } 

so in template have this

<button ng-click="delegate('add_inscription')">add inscription</button> 

i don't know if thinking in right direction either,, point actions object pretty large , don't want write massive switch case statement have update time.

is there way in angular?

i have no problem doing in straight javascript

var fnstring = "add_inscription";  // find object var fn = window[fnstring];  // if object function if (typeof fn === "function") fn(); 

but in angular can't done..

assuming "actions" functions defined inside scope, like:

$scope.add_inscription = function(){ ... } 

you should do:

var _action = 'add_inscription'; $scope[_action]();
