如何访问指令的内部指令

Question

I've directives container and item .

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


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

They are supposed to be used like this:

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

Expected output html:

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

How to take item directives from container content and render them as repeatable directive in place of ... at container template?

Answer 1

Since directive templates must have exactly one html root element, template: "item" is not valid. It has to be at least something like template: '<span>item</span>' , which produces:

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

The two directives are:

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

Use the transclude: true option :

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