Can anyone assist me with passing controller definitions to the inner directive that is nested within the outer directive? You can refer to this link for an example that may or may not work.
1) In order for the inner directive to have access to the parent controller, you can utilize the require parameter within the inner directive's configuration. It would look something like this:
angular.module('docsTabsExample', [])
.directive('outer', function() {
return {
restrict: 'E',
transclude: true,
scope: {},
templateUrl: '...',
controllerAs: 'outer',
bindToController: true,
controller: function(scope, element, attrs) {
}
}
})
.directive('inner', function() {
return {
require: '^outer',
restrict: 'E',
transclude: true,
scope: {
title: '@'
},
controllerAs: 'inner',
bindToController: true,
templateUrl: '...',
controller: function(scope, element, attrs, tabsCtrl) {
},
};
});
2) The current value of controller: controller references an empty function. You should replace it with a properly defined function as shown above, and ensure that you include bindToController: true.
After exploring different methods, I approached the solution by delving deep into abstraction. The process involved dynamically creating the entire directive configuration object and then proceeding to lazily register it.

angular.module('app', ['moduleLazyLoader'])
.controller('mainCtrl', ['$log', function ($log) {
this.list = [
{
name: 'asd',
ctrl: [
'ItemAsdCtrl',
function () {
$log.debug('ItemAsdCtrl');
}
]
},
{
name: 'xyz',
ctrl: [
'ItemXyzCtrl',
function () {
$log.debug('ItemXyzCtrl');
}
]
}
];
}])
.directive('outer', ['factoryLazyLoader', '$log', '$compile', function (factoryLazyLoader, $log, $compile) {
function controller () {}
return {
restrict: 'E',
controller: controller,
controllerAs: 'outer',
bindToController: true,
scope: {
list: '=list'
},
link: function (scope, element, attributes) {
var directives = [];
scope.outer.list = scope.outer.list.map(function (ele, idx) {
var directiveSuffix = ele.ctrl[0];
directiveSuffix[0].toUpperCase();
var directiveName = 'item' + directiveSuffix,
directiveAttrName = directiveName.split(/(?=[A-Z])/).join("-").toLowerCase();
directives.push(directiveAttrName);
factoryLazyLoader.registerDirective([
directiveName,
function () {
return {
restrict: 'E',
replace: true,
controller: ele.ctrl[1],
controllerAs: ele.ctrl[0],
bindToController: true,
template: '<div>{{' + ele.ctrl[0] + ' | json}}</div>',
scope: {
item: '=item'
}
}
}
])
return ele;
});
var tpl = '<div>';
angular.forEach(directives, function (val, idx) {
tpl += '<' + val +' item="outer.list[' + idx + ']">' + '</' + val + '>';
});
tpl += '</div>'
// debugger;
element.replaceWith($compile(tpl)(scope))
}
};
}])
