AngularJS 在自定义指令中包装 ui-select [英] AngularJS Wrapping a ui-select in a custom directive

问题描述

我正在尝试将 ui-select 包装在自定义指令中.(https://github.com/angular-ui/ui-select)>

this.adminv2.directive('eventSelect', function() {返回 {限制:'E'，替换:真的，范围: {ngModel: '=',占位符:'='},控制器:函数($scope，$http){返回 $scope.refreshEvents = 函数(searchTerm){return $http.get('/events/autocomplete', {参数:{术语:搜索术语}}).then(函数(响应){返回 $scope.events = response.data;});};},模板:<div>{{ngModel}}\n <ui-select ng-model=\"ngModel\"\n theme=\"bootstrap\"\n ng-disabled=\"disabled\"\nreset-search-input=\"false\">\n \n \n

"};});

select 正常工作，但与 ng-model 的绑定不起作用.我无法设置模型或读取它.我不明白，因为当我使用诸如

之类的简单模板时它可以工作

有什么特别的事情要做，因为我在指令中包装了一个指令?

解决方案

我设法通过将模板中的 ng-model 设置为

来使绑定工作

ng-model="$parent.ngModel"

I'm trying to wrap a ui-select in a custom directive. (https://github.com/angular-ui/ui-select)

this.adminv2.directive('eventSelect', function() {
    return {
      restrict: 'E',
      replace: true,
      scope: {
        ngModel: '=',
        placeholder: '='
      },
      controller: function($scope, $http) {
        return $scope.refreshEvents = function(searchTerm) {
          return $http.get('/events/autocomplete', {
            params: {
              term: searchTerm
            }
          }).then(function(response) {
            return $scope.events = response.data;
          });
        };
      },
      template: "<div>{{ngModel}}\n  <ui-select ng-model=\"ngModel\"\n             theme=\"bootstrap\"\n             ng-disabled=\"disabled\"\n             reset-search-input=\"false\">\n    <ui-select-match placeholder=\"Enter an event\">{{$select.selected.name}}</ui-select-match>\n    <ui-select-choices repeat=\"event in events track by $index\"\n             refresh=\"refreshEvents($select.search)\"\n             refresh-delay=\"0\">\n      <span ng-bind-html=\"event.name | highlight: $select.search\"></span>\n      <i class=\"icon-uniF111 fg type-{{raceType}} pull-right\" ng-repeat='raceType in event.racetypes'></i>\n      <br>\n      {{event.dates}} <i class='pull-right'>{{event.location}}</i>\n    </ui-select-choices>\n  </ui-select>\n</div>"
    };
  });

The select works properly, but the binding with ng-model doesn't work. I cannot set the model or read it. I don't get it since it works when I use a simple template such as

<div><input ng-model="ngModel"></div>

Is there something special to do because I wrap a directive in directive ?

解决方案

I managed to make the binding work by setting the ng-model in the template as

ng-model="$parent.ngModel"
