Transclusion of AngularJS directive templates

Presently, there is an element structured like this:

<input test class="foo bar" ng-model="foo" name="foo"/>

My goal is to transform it into the following format when it includes the "test" attribute:

<div class="something">
    <input type="text" class="foo bar" ng-model="foo" name="foo"/>
    <span>test</span>
</div>

However, I'm encountering issues with transclusion. Instead of transferring the attributes to the input, they are being added to the div element. This results in a structure like:

<div class="something foo bar" type="text" ng-model="foo" name="foo">
    <input/>
    <span>test</span>
</div>

Below is the directive implementation:

.directive('test', [function () {
     return {
        transclude:true,
        replace:true,
        template:'<div class="something">\
            <input ng-transclude>\
            <span>hi</span>\
        </div>',
        link: function (scope, element, attrs, ngModel) {
            // do stuff
        }
    }
}])

Answer №1

This method won't work for transclusion:

<input test class="foo bar" ng-model="foo" name="foo"/><!-- NOT RECOMMENDED -->

For successful transclusion, I suggest using an element-level directive like this:

<test>
    <input class="foo bar" ng-model="foo" name="foo"/>
</test>

If you go with the above approach, your directive's template should look like this:

template:
    '<div class="something">\
        <ng-transclude />\
       <span>hi</span>\
   </div>',

Answer №2

If you're looking for a solution, consider using this directive:

JavaScript

var app = angular.module('app',[]);
function myCtrl($scope){

}
app.directive("test",function(){
  return {
    template: '<div class="something"><input type="text" class="foo bar" ng-model="foo" name="foo"/><div ng-transclude></div></div>',
    transclude: true,
    replace: true
  };
});

HTML

<div test ng-controller="myCtrl">
  <span>333</span>
</div>

The output will look like this:

<div class="something ng-scope" test="" ng-controller="myCtrl">
  <input type="text" class="foo bar ng-pristine ng-valid" ng-model="foo" name="foo">
  <div ng-transclude="">
    <span class="ng-scope">333</span>
  </div>
</div>
