如何将角度引导程序延迟到服务电话之后 [英] How to delay angular bootstrap until after a service call

问题描述

我是angular的初学者.我需要进行多个Web服务调用，然后引导我的模型.我尝试将以下代码放入所有网络服务运行后执行的函数中.

I'm a beginner on angular. I've got a need to make multiple webservice calls and then bootstrap my model. I've tried placing the following code inside my function that is executed after all webservices have run.

        var myApp = angular.module('myApp', [])
        myApp.controller('Ctrl', ['$scope', function ($scope) {
            $scope.obj = model
        }]);

        angular.element(document).ready(function () {
            angular.bootstrap(document, ['myApp']);
        });

但是我收到以下异常.

[$ injector:modulerr]由于以下原因，无法实例化模块myApp:[$ injector:nomod]模块'myApp'不可用！您可能拼错了模块名称，或者忘记了加载它.如果要注册模块，请确保将依赖项指定为第二个参数.

[$injector:modulerr] Failed to instantiate module myApp due to: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

我的代码仍然有效，但是我想摆脱异常，更重要的是，了解延迟引导时应如何构造角度代码.

My code still works, but I want to get rid of the exception and more importantly learn how the angular code should be structured when the bootstrapping is delayed.

我不知道这是否会有所帮助，但以防万一.

I don't know if this will help, but I'm including it in case.

    <div ng-app ng-controller="Ctrl">
       <div ng-repeat="o in obj track by $index">
       </div>
       <input id="Model" type="hidden" value="{{obj}}" />
    </div>

推荐答案

我从较早的尝试中发现可以将其添加到html标记中.

I found from earlier attempts to get it working that I added the following to the html tag.

ng-app="myApp" 

当我删除它时，我的错误消失了.我相信这是执行自动引导的方式，但是由于我需要延迟引导，所以这会引起问题.这是有关该指令的更多信息的链接

When I removed it my error went away. I believe this is how you would perform automatic bootstrapping, but since I needed delayed bootstrapping it was causing issues. Here is a link for more information on the directive

ng-app指令

如果更熟悉angular的人可以验证我的理解，我将不胜感激.谢谢阿伦的小提琴.

If someone more familiar with angular could verify my understanding I would appreciate it. Thank you Arun for your fiddle.
