AngularJS 应用程序中的 $timeout 未定义错误 [英] $timeout not defined error in AngularJS app

问题描述

我有以下代码:

app.factory('Position', ['$timeout', function() {

    var position = {
        latitude: 44,
        longitude: 26
    };

    console.log("Timeout started");

    $timeout(function() {
        position.latitude += 15;
        position.longitude += 15;
    }, 2000);

    return position;
}]);

我在 Javascript 控制台中得到 $timeout not defined .我是不是没有正确注入服务的依赖项?

And I get $timeout not defined in Javascript console. Am I not injecting the dependency of the service correctly ?

推荐答案

您没有注入 $timeout.应该是这样的.

You did not inject $timeout. It should be as follows.

app.factory('Position', ['$timeout', function($timeout) {
    ...
}]);

以这种方式声明可确保在您的 JavaScript 代码缩小时正确识别服务.有关这如何帮助缩小的更多信息，请参阅 关于缩小的说明 和 声明用于缩小的 AngularJS 模块

Declaration this way ensures that services are correctly identified when your JavaScript code gets minified. For further information on how this helps minification, see A Note on Minification and Declaring AngularJS Modules For Minification

如果缩小不在您的计划中(例如用于快速测试)，您可以简单地使用

If minification is not in your plans (e.g for quick test), you can simply go with

app.factory('Position', function($timeout) {
    ...
});
