angular error in declaring multiple modules

I m new to Angular JS (apologies if my my terminology is incorrect or not enough explained).

I m trying to do a demo creating multiple modules which are just returning messages. My domo has just 2 files, I m copying complete code below.

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>

Issue: If I create a just one module it works fine but if I create 2 modules it give weird error. Can you please guide me who to fix this error and create multiple modules and consume them.

Solution

  • You seem to be declaring a MainController controller, but you reference MainController1 in the ng-controller directive.

    Try this line instead:

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

    Also, I don't get what you are trying to do with these lines of code:

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

    Try removing those extra brackets as shown below:

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

    If you open the provided link (this one) it shows the following message:

    Syntax Error: Token 'message2' is unexpected, expecting [:] at column 16 of the expression [ {{message2] starting at [message2].

    So yes, the error is thrown because you are using an invalid expression in your HTML template.
