如何从模块依赖调用函数(另一个模块) [英] how to call a function from module dependency (another module)
本文介绍了如何从模块依赖调用函数(另一个模块)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想为分页创建单独的模块,因为我需要它在不同的模块中重用,但我不知道如何从模块依赖(另一个模块)调用函数
I want to create seperate module for pagination, because I will need it to reuse in different modules, but I don't know how to call a function from module dependency (another module)
这是我的主要模块:
var App = angular.module('search', ['pagination']);
App.controller('MainController', ['$scope', '$pagination' function($scope, $pagination) {
$scope.testFunction(); //function from pagination module controller
}])
这是我的分页模块:
var App = angular.module('pagination', []);
App.controller('PaginationController', ['$scope', function($scope) {
$scope.testFunction = function(){
console.log("pagination module");
}
}])
我收到错误:
Error: [$injector:unpr] Unknown provider: $paginationProvider <- $pagination
推荐答案
要在两个模块之间共享资源,请声明工厂或服务。
To share resources across two modules, declare a factory or a service.
假设你有一个搜索模块:
Suppose you have a search module:
//you inject your pagination module here
var searchModule = angular.module('search', ['pagination']);
//and you ALSO need to inject your pagination's service into your controller
searchModule.controller('MainController', ['$scope', 'paginationSvc' function($scope, paginationSvc) {
//function from pagination module controller
paginationSvc.testFunction();
}])
你的分页模块:
var pagination = angular.module('pagination', []);
//declare your pagination service here
pagination.factory('PaginationSvc', [function(){
return {
testFunction:testFunction
};
function testFunction(){
console.log('This is from pagination module');
}
}])
