我是 Angular.JS 的新手，我正在尝试进行依赖注入，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 http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2734:15
    at Object.getService [as get] (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2862:39)
    at http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2739:45
    at getService (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2862:39)
    at Object.invoke (http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js:2880:13)

    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

工厂的定义Reload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);
});

您将load提供程序传递给您的Reload，这意味着load需要在应用程序中声明服务。

如果我理解正确，我认为您需要添加

app.factory('load', function(){
  document.reload();
});

在您的Reload声明之前，如果您在同一个文件中执行所有这些操作。

话虽如此，除非您需要特别复杂的重新加载，否则我会简单地load从注射中取出并将其包含在$timeout类似内容中

return $timeout(document.reload, timeout);

我解决了将代码更改为：

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

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

感谢同事...
