Angular 指令 - 要求嵌入? [英] Angular directive - asking for transclusion?

问题描述

我在下面收到一个错误，我不明白为什么.有什么想法吗?

html,

<button ng-click="loadForm()">加载指令表单</button><div data-my-form></div>

角度，

 app.directive('myForm', function() {返回 {替换:真，控制器:功能($范围){$scope.isLoaded = false;$scope.loadForm = function(){$scope.isLoaded = true;}},模板:'<div ng-if="isLoaded" ng-include="\'form.php\'" ></div>',链接:功能(范围，元素){}}});

错误，

错误:[$compile:multidir] 多个指令 [ngInclude, ngInclude] 要求嵌入:<div data-my-form="" ng-if="isLoaded" ng-include="'form.php'">

修复，

'<div><div ng-if="isLoaded" ng-include="\'form.php\'" ></div></div>'

但是为什么我必须将它包装在一个 div 中?这是一个角度错误吗?

解决方案

错误很明显.在试图使用嵌入的同一元素上有两个指令:

<代码>1.ng-if2. ng-包含

一个元素只能应用一个嵌入.

要解决此问题，请改为尝试:

<div ng-include="'form.php'">

I get an error below and I don't understand why. Any ideas?

html,

<button ng-click="loadForm()">Load Directive Form</button>
<div data-my-form></div>

angular,

   app.directive('myForm', function() {
        return {
          replace:true,
          controller:function($scope){
            $scope.isLoaded = false;
            $scope.loadForm = function(){
              $scope.isLoaded = true;
            }
          },
          template: '<div ng-if="isLoaded" ng-include="\'form.php\'" ></div>',
          link:function(scope, element) {

          }
        }
    });

error,

Error: [$compile:multidir] Multiple directives [ngInclude, ngInclude] asking for transclusion on: <div data-my-form="" ng-if="isLoaded" ng-include="'form.php'">

a fix,

'<div><div ng-if="isLoaded" ng-include="\'form.php\'" ></div></div>'

but why do I have to wrap it in a div? is it a angular bug?

解决方案

The error is clear. There are two directives on the same element that is trying to use transclusion:

1. ng-if 
2. ng-include

An element can only apply one transclusion.

To fix, try this instead:

<div data-my-form="" ng-if="isLoaded">
   <div ng-include="'form.php'"> </div>
</div>
