Question

所以我想用我的配置创建一个嵌入了角度ui-select指令的指令。但是，当我将变量传递给ng-model时，它不会在父项中更新。只有在ui-select本身。我假设在隔离范围内调用'='会导致双向数据绑定。我必须在某个地方拨打$ apply吗？有什么帮助吗？

所以我的html用法应该是这样的：

<interpreter-search ng-model="booking.interpreterId" id="field_interpreter"/>

指令：

angular.module('omserviceApp')
.directive('interpreterSearch', ['InterpreterSearch' , function (InterpreterSearch) {
    return {
        restrict: 'E',
        scope:{
          interpreterId: '=ngModel'
        },
        link: function (scope, element, attrs) {

            scope.refreshInterpreters = function (query) {
                InterpreterSearch.query({query: query}, function (result) {
                    scope.interpreters = result;
                }, function (response) {
                    if (response.status === 404) {
                        scope.interpreters = [];
                    }
                });
            };

        },
        templateUrl: 'scripts/components/entities/interpreter/interpreter-search.html'
    }
}]);

模板：

<ui-select ng-model="interpreterId">
<ui-select-match placeholder="Find an interpreter...">
    <span ng-bind="interpreterId"></span>
</ui-select-match>
<ui-select-choices repeat="interpreter.id as interpreter in (interpreters | filter:  $select.search)"
                   refresh="refreshInterpreters($select.search)"
                   refresh-delay="0">
    <span ng-bind="interpreter | interpreterHtml"></span>
</ui-select-choices>

Angular js指令双向数据绑定不起作用
