Question:

What is DDO Directive Definition Object?

Answer:

“DDO is an object used while creating a custome directive. A standard DDO object has following parameters.

var directiveDefinitionObject = {
    priority: 0,
    template: '

', // or // function(tElement, tAttrs) { ... }, // or // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... }, transclude: false, restrict: 'A', templateNamespace: 'html', scope: false, controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, controllerAs: 'stringIdentifier', bindToController: false, require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], compile: function compile(tElement, tAttrs, transclude) { return { pre: function preLink(scope, iElement, iAttrs, controller) { ... }, post: function postLink(scope, iElement, iAttrs, controller) { ... } } // or // return function postLink( ... ) { ... } }, // or // link: { // pre: function preLink(scope, iElement, iAttrs, controller) { ... }, // post: function postLink(scope, iElement, iAttrs, controller) { ... } // } // or // link: function postLink( ... ) { ... } };"
