I am currently developing a directive for AngularJS. How can I specifically configure it to require being a child of directiveA?
For instance, consider the following example:
<my-modal>
<m-header>Header</m-header>
</my-modal>
In this scenario, m-header must always be a direct child of my-modal. If not, an exception will occur.
One way to utilize the require parameter is by incorporating it to call a parent directive, as demonstrated in the code snippet below.
app.directive('mHeader', function() {
return {
require: '^^myModal',
restrict: 'E',
transclude: true,
link: function(scope, element, attrs, myModalCtrl) {
myModalCtrl.close();
},
templateUrl: 'my-header.html'
};
});
Furthermore, with the use of require, you gain access to the parent controllers just like the example where myModalCtrl is accessed.
Here is a clever solution you can use: By checking if the parent element's local name is 'my-model' using JavaScript, you are able to determine if it is a direct child of that element.
