I want to implement a search box in my angularJs application. As soon as user starts typing some name in the search box , some REST service should be called and it should fetch

Answer 1

Found this to be a simplification of the accepted answer.

// Directive
app.directive('search', function () {
    return function ($scope, element) {
        element.bind("keyup", function (event) {
          var val = element.val();
          if(val.length > 2) {
            $scope.search(val);
          }
        });
    };
});

// In Controller
$scope.search= function(val) {
  // fetch data
}

// HTML
