Enhancing the angular-ui-bootstrap typeahead module

Currently, I am using the typeahead feature from angular-ui-bootstrap to allow users to select a person's name or add a new name if it is not available in the options.

I have customized the getMatchesAsync function with the following code:

 if(scope.matches.length < 4 || scope.matches.length == undefined){
    scope.matches.push({
      id: getMatchId(matches.length),
      label: 'Add New +',
      model: 'new'
    });
  }

However, I understand that this is not a sustainable solution, especially when the component is updated.

Where should I place this code and how can I effectively integrate it into the component? Typeahead module: https://github.com/angular-ui/bootstrap/blob/master/src/typeahead/typeahead.js

Answer №1

Check out this example I provided in response to the feedback...

someModule.filter('filterWithNew', function($filter) {
    return function(array, expression, comparator) {
        var matches = $filter('filter')(array, expression, comparator);

        if (matches.length < 4) {
            matches.push({
                label: 'Add new +',
                model: 'new'
            });
        }
        return matches;
    };
});

After implementing the above, you can then utilize

... typeahead="name.label for name in names | filterWithNew:$viewValue"
