angularjs - 如何在 AngularJS 指令中使用定义的文本/ng-模板

Question

我尝试编写一个非常灵活的指令。为此，我希望用户定义一个在我的返回部分使用的模板(如 ui-bootstrap typeahead directive 中所示)。

所以我这样定义我的模板:

<script type="text/ng-template" id="myDirectivesCustomTemplate.html">
  <ul>
    <li ng-repeat="value in values">
      <a ng-click="doSomething(value.id)">
        {{value.name}}
      </a>
    </li>
  </ul>
</script>

我在我的指令中设置了这个模板

<div 
  my-directive 
  my-directive-custom-template="myDirectivesCustomTemplate.html" 
  my-directive-data="someScopeData">

现在在我的指令中，如何呈现自定义模板并将其与传递的数据一起使用？当我尝试使用它直接在模板中返回时，它会抛出 ReferenceError: $scope is not Defined 错误。如果我在没有范围的情况下调用它，它会显示ReferenceError:myDirectiveCustomTemplate未定义错误。

如果我不想直接将其用作返回，我可以在哪里以及如何使用我的模板？

编辑:比方说，这是我的指令:

(function() {
 'use strict';
 var Combobox = function() {

  var displayInputField     = elem.find('input.dropdown');

  scope.$watch(scope.nsdComboboxModel,function(newVal){
    /* search for newVal in given data object */
    scope.setDisplayInputValue(newVal);
  });

  scope.setDisplayInputValue = function(value)
  {
    displayInputField.val(value);
  };

  scope.elementSelected = function (item, model, label) {
    scope.ComboboxCallback(item);
    scope.setDisplayInputValue(label);
  };
 }


 return {
   restrict: 'A',
   transclude: true,
   scope: {
     Combobox:                  '@', /* used as HTML/CSS-id/name/path */
     ComboboxModel:             '=', /* the actual AngularJS model (ng-model) */
     ComboboxAutocompleteData:  '=', /* the data used for autoComplete (must be array of objects having id and value) */
     ComboboxDropdownData:      '=', /* data used by the dropdown template */
     ComboboxCallback:          '=', /* a callback function called with selected autocomplete data item on select */
     ComboboxLabel:             '@', /* label for the input field */
     ComboboxDropdownTemplate:  '@'  /* label for the input field */
 },

 template:

  '<section class="-combobox-directive container-fluid">' +
    '<label for="{{Combobox}}" ng-if="ComboboxTranslation" translate="{{ComboboxLabel}}"></label>' +
    '<div class="combobox input-group">' +
      '<input type="text" ' +
        'id="{{Combobox}}" ' +
        'autocomplete="off" ' +
        'ng-model="ComboboxDestinationDisplay" ' +
        'data-toggle="dropdown" ' +
        'typeahead="value as location.value for location in ComboboxAutocompleteData | filter:$viewValue" ' +
        'typeahead-editable="false" ' +
        'typeahead-on-select="elementSelected($item, $model, $label)" ' +
        'class="form-control dropdown">' + // dropdown-toggle

        '<span data-toggle="dropdown" class="input-group-addon dropdown-toggle">' +
          '<span class="glyphicon glyphicon-globe"></span>' +
        '</span>' +

        //$compile(ComboboxDropdownTemplate) +

    '</div>' +
  '</section>',

  link: link
 };
};

angular.module('vibe.directives').directive('nsdCombobox', [NsdCombobox]);
})();

HTML

<script type="text/ng-template" id="myDirectivesCustomTemplate.html">
    <ul>
        <li ng-repeat="value in values">
        <a ng-click="doSomething({id:value.id})">
                            {{value.name}}
        </a>
        </li>
    </ul>
</script>
<div ng-controller="MainCtrl">
     <div my-directive template="myDirectivesCustomTemplate.html" mydata="mydata" mycallback="doSomething(id)"></div>
</div>

JS

app.controller('MainCtrl',function($scope){
    $scope.mydata = [{id:1,name:'One'},{id:2,name:'Two'},{id:3,name:'Three'}];
    $scope.doSomething = function(id){
        alert(id); 
    }
});
app.directive('myDirective', function($templateCache,$compile) {
    return {
        restrict: 'A',
        scope:{
            template : "@",
            mydata : "=",
            mycallback:"&"
        },
        link: function(scope,element) {
            var template = $templateCache.get(scope.template);
            scope.values = scope.mydata;
            scope.doSomething = scope.mycallback;
            element.append($compile(template)(scope));
        }
    }
});
