Utilizing transclude in directives proves to be extremely beneficial when you want the scope of your controller to be linked to the HTML being passed in.
But how can you achieve the opposite? (accessing the directive's scope from the controller)
Here is an example illustrating my goal:
<my-directive model='controllerModel'>
{{directiveModel}}
</my-directive>
.directive(function () {
return {
transclude: true,
template: '<div ng-transclude></div>',
scope: {
directiveModel: '=model'
}
}
})
In this scenario, the 'directiveModel' scope property is accessible within the "transcluded" HTML.
Despite it not working by default due to the controller's scope being bound to the provided HTML.
Finding a way to access the directive's scope from the controller remains a mystery for me.
The most feasible approach I can think of involves avoiding transclude and instead using .html() to insert HTML into a template, then utilizing the $interpolate service to bind the directive's scope to the HTML content.
The challenge arises when defining a template for the directive because Angular replaces the incoming HTML with the directive's HTML before accessing it.
