"Unlocking the hidden powers within a directive: A guide to accessing inner

I have two directives called container and item.

directive('container', function(){
    return {
        replace: true,
        template: "<div>contains <p>...</p> </div>'
    }
});


directive('item', function(){
    return {
        replace: true,
        template: "item"
    }
});

These directives are intended to be used in the following way:

<container>
    <item>
    <item>
    <item>
</container>

The expected output HTML should look like this:

<div>contains <p>item item item </p> </div>

How can I extract the item directives from the content of the container directive and render them as repeatable directives in place of the ... within the container template?

Answer №1

When working with directive templates, it is important to remember that they must contain exactly one HTML root element. Using template: "item" is not valid as it does not adhere to this rule. Instead, the template should be something like

template: '<span>item</span>'
, which will generate:

<div>
    contains 
    <p>
        <span>item</span>
        <span>item</span>
        <span>item</span>
    </p>
</div>

The following are two directives being used:

app.directive('container', function() {
  return {
    restrict: 'E',
    replace: true,
    transclude: true,
    template: '<div>contains <p ng-transclude></p></div>'
  };
});

app.directive('item', function() {
  return {
    restrict: 'E',
    replace: true,
    template: '<span>item</span>'
  };
});

Answer №2

Implement the transclude: true setting :

directive('wrapper', function(){
    return {
        replace: true,
        transclude: true,
        template: "<section>includes <p ng-transculde></p> </section>'
    }
});
