如何在AngularJS指令中使用定义的text/ng-template

Question

我尝试写一个非常灵活的指令.为此,我希望用户定义在返回的一部分中使用的模板(如ui-bootstrap typeahead指令中所示).

所以我定义我的模板如下:

<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返回模板时,它会抛出一个ReferenceError: $scope is not defined错误.如果我在没有范围的情况下调用它,则表示ReferenceError: myDirectiveCustomTemplate is not defined错误.

如果我不想直接使用它作为回报,我在哪里以及如何使用我的模板？

编辑:让我们说,这是我的指示:

(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));
        }
    }
});

看看你的指令我可以建议试试ng-include.你想去哪里

//$compile(ComboboxDropdownTemplate) +

    '</div>'

改为

<span ng-include='templateUrlPropertyOnScope'>

'</div>'

templateUrlPropertyOnScope属性应指向服务器端或使用创建的脚本部分中的模板type=text/ng-template.

我知道这是四年后的事了，但如果有人仍然有这个问题，也许这个答案也可能有用。

使用这样的简单指令：

<my-directive template="custom-template.html"></my-directive>

然后，您可以在指令中引用模板属性，如下所示：

(function() {
  angular
    .module('app')
    .directive('myDirective', myDirective);

  function myDirective() {
    return {
      restrict: 'E',
      templateUrl: function(elem, attrs) {
        return attrs.template;
      }
    }
  }
}
