Question

我是Angular JS的新手（如果我的术语不正确或解释不充分，请道歉。）

我正在尝试创建一个只返回消息的多个模块的演示。我的domo只有2个文件，我在下面复制完整的代码。

JS：

var app = angular.module("app", ['controllers1', 'controllers2']);

    angular.module('controllers1', []).controller('MainController', function($scope) {

        $scope.message1 = "controllers1 message";
        $scope.func1 = function () {
            return "controllers1 func";
        }

        }
    );

    angular.module('controllers2', []).controller('MainController2', function ($scope) {

        $scope.message2 = "controllers2 message";
        $scope.func2 = function () {
            return "controllers2 func";
        }

    }
    );

HTML：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" ng-app="app">
    <head>
        <title></title>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
        <script src="JS/Index.js"></script>

    </head>
    <body>
        {{2+2}}

        <div ng-controller="MainController1">
            {{message1}}
            {{func1()}}
            <br /><br/>

            <div ng-controller="MainController2">
                {{
                {{message2}}
                {{func2()}}
                }}
            </div>

        </div>
    </body>
</html>

问题： 如果我创建一个只有一个模块，它工作正常，但如果我创建2个模块，它会给出奇怪的错误。您能否指导我修复此错误并创建多个模块并使用它们。

Answer 1

您似乎在声明MainController控制器，但您在MainController1指令中引用了ng-controller。

请尝试使用此行：

angular.module('controllers1', []).controller('MainController1', function($scope) {

另外，我不知道你要对这些代码行做什么：

<div ng-controller="MainController2">
    {{
        {{message2}}
        {{func2()}}
    }}
</div>

尝试删除这些额外的括号，如下所示：

<div ng-controller="MainController2">
    {{message2}}
    {{func2()}}
</div>

如果您打开提供的链接（this one），则会显示以下消息：

语法错误：令牌'message2'是意外的，期望[：]在列 16的表达[ {{message2]从[message2]开始。

所以是的，因为您在HTML模板中使用了无效的表达式而引发错误。

Answer 2

请检查此工作CODE - PLUNKER LINK

你遇到的问题是大括号

      {{ //remove this
            {{message2}}
            {{func2()}}
      }} //remove this as well

也是danilo指出的

angular.module('controllers1', [])
.controller('MainController1', function($scope) {

声明多个模块时的角度误差
