我尝试编写一个非常灵活的指令。为此,我希望用户定义一部分返回时使用的模板(如ui-bootstrap typeahead directive中所示)。
所以我定义了这样的模板:
<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返回模板时,它会抛出ReferenceError: $scope is not defined
错误。如果我在没有范围的情况下调用它,则会显示ReferenceError: myDirectiveCustomTemplate is not defined
错误。
如果我不想直接使用我的模板,我可以在哪里以及如何使用我的模板?
编辑:让我们说,这是我的指示:
(function() {
'use strict';
var Combobox = function() {
var displayInputField = elem.find('input.dropdown');
scope.$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]);
})();

});

查看您的指示我可以建议尝试ng-include
。你想去哪里
//$compile(ComboboxDropdownTemplate) +
'</div>'
将其更改为
<span ng-include='templateUrlPropertyOnScope'>
'</div>'
templateUrlPropertyOnScope
属性应指向服务器端或使用type=text/ng-template
创建的脚本部分中的模板。

您可以使用$http
和$compile
来完成此任务。
app.directive('myDirective', function($http, $templateCache, $compile) {
return {
scope: {
// reference to your data.
// Just use `data.values` or `data.whatever` in your template
data: '=myDirectiveData'
},
link: function(scope, elm, attrs) {
// Load the template via my-directive-custom-template attribute
$http.get(attrs.myDirectiveCustomTemplate, {cache: $templateCache}).success(function(html) {
// update the HTML
elm.html(html);
// compile the html against the scope
return $compile(elm.contents())(scope);
});
}
};
});
我希望它能给你一个良好的开端

我知道这是4年后的事情,但是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;
}
}
}
}
