送的属性阵列指令 [英] send array of attributes to directive

问题描述

我读 NG-ATTR 指令，但我想给属性的阵列指令为例：

I read about ng-attr for directive, but I want to send array of attributes to directive as example:

<myElement attributes="attributes"></myElement>

和我的指令为例：

myApp.directive('myElement', function(){
 return {
    restrict: 'E',
    require: 'ngModel',
    template: '<div>' + 
              '<!-- I want to add this attributes on the div element>' + 
              '</div>',
    replace: true,
    scope: {
        attributes: '=attributes'
    },            
  }
});

和属性是控制器为以下几点：

And the attributes is in controller as the following:

$scope.attributes = {"class": "test", "id": "test", "style": "color: 'red'"}

所以，我怎么能在指令设置在元素属性的阵列？

So, How can I set array of attributes in element in directive ?

推荐答案

在你的指令链接功能

link:function(scope, element, attrs){
     var templateElement = angular.element(element[0].firstChild) //this is you template div el.
      angular.forEach(scope.attributes, function(value, key){
           //if you want to set the root element
           attrs.$set(key, value)
           //if you want to set template root div
          templateElement.attr(key, value)
      })
}
