[AngularJS] Adding custom methods to angular.module

浏览数：33 / 时间：2015年06月09日

There are situations where you might want to add additional methods toangular.module. This is easy to accomplish, and can be a handy technique.

    //For directive template
    <hello></hello>

    //For directive controller
    <li menu-item ng-repeat="category in categories"
        class="menu-animation"
        ng-class="{‘highlight‘:mouse_over}"
        ng-mouseenter="mouse_over = true"
        ng-mouseleave="mouse_over = false"
        ng-class="{‘active‘:isCurrentCategory(category)}">
        <a  ng-click="setCurrentCategory(category)">
            {{category.name}}
        </a>
    </li>

var original = angular.module;

angular.module = function(name, deps, config){

    var module = original(name, deps, config);

    module.quickTemplate = function(name, template){
        module.directive(name, function() {
            return {
                template: template
            }
        });
    };

    module.quickController = function(name, controller) {
        module.directive(name, function() {
            return {
                controller: controller
            }
        })
    };

    return module;
};

Use: We comment out the meunItem directive, instead using quickController method added to the end of the file.

angular.module(‘categories‘, [
    ‘eggly.models.categories‘,
    ‘ngAnimate‘
])

    .config(function ($stateProvider) {
        $stateProvider
            .state(‘eggly.categories‘, {

                views: {
                    ‘categories@‘: {
