angularjs - "Error: Unknown provider"试图在 Angular.JS 中实现依赖注入(inject)

Question

我是 Angular.JS 的新手，我正在尝试进行依赖注入(inject)，但我得到了这个:

// Definition
app.factory('Reload', function (load, $timeout, timeout) {
    if (!timeout) {
        timeout = 15 * 1000; // reload page every quater minute by default
    }
    return $timeout(load, timeout);
});


// Controller
app.controller('SomeController', function ($scope, $routeParams, $location, $timeout, Installer, Reload) {
  Reload(load, $timeout, 1000);
});

Error: Unknown provider: loadProvider <- load <- Reload
    at Error (<anonymous>)

    at Object.instantiate (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2914:23)

我错过了什么？谢谢

Reload 的定义factory 在工厂定义和它返回的函数之间混淆了。如下更新您的代码。

// Definition
app.factory('Reload', function ($timeout) {
    return function(load, timeout) {
        if (!timeout) {
            timeout = 15 * 1000; // reload page every quater minute by default
        }
        return $timeout(load, timeout);
    }
});


// Controller
app.controller('SomeController', function ($scope, $routeParams, $location, $timeout, Installer, Reload) {
  Reload(load, 1000);
});
