Split camel case string with space using angularjs filter

I want to split camel case string to regular form and want to use customize filter.

<select class="form-control" ng-model="emailsettingType" ng-change="emailsettingTypeChange()" name="emailsettingType" ng-required="true">
<option ng-repeat="opt in emailtypesforuser">{{opt|splitCamelCase}}</option>
</select>

Solution

This can be customized to fit your needs.

.filter('splitCamelCase', [function () {
  return function (input) {

    if (typeof input !== "string") {
      return input;
    }

    return input.split(/(?=[A-Z])/).join(' ');

  };
}]);

Remove the toUpperCase() if you do not want every first character capitalized.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.emailtypesforuser = ['OneType', 'AnotherType', 'thisType', 'thatType', 'THatTypppeRRR'];
});

app.filter('splitCamelCase', [function () {
  return function (input) {

    if (typeof input !== "string") {
      return input;
    }

    return input
     .replace(/([A-Z])/g, (match) => ` ${match}`)
     .replace(/^./, (match) => match.toUpperCase());

  };
}]);
