问题描述

如果我的问题太基础，请原谅我.我正在学习 AngularJS 的控制器.

这是项目结构.

这是我的 html:

<头><script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script><script src="js/controllers.js"/><身体><div ng-controller="numberController"><input type = "text" ng-model = "number.number1" placeholder = "在此处输入数字"><input type = "text" ng-model = "number.number2" placeholder = "在此处输入另一个数字">{{number.number1}} + {{number.number2}} = {{number.sumIt()}}

</html>

这是我的控制器:

function numberController($scope) {$scope.number = {编号 1:0，数字2:0，sumIt:函数(){var numberObject;numberObject = $scope.number;返回 parseInt(numberObject.number1) + parseInt(numberObject.number2);}};}

网页甚至无法加载.

我哪里出错了?

我得到的错误:我得到这个错误:https://docs.angularjs.org/error/$injector/modulerr?p0=sa-app&p1=Error:%20%5B$injector:nomod%5D%20http:%2F%2Ferrors.angularjs.org%2F1.3.3%2F$injector%2Fnomod%3Fp0%3Dsa-app%0A%20%20%20%20at%20Error%20(native)%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:6:416%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:366%0A%20%20%20%20at%20a%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:7)%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:250%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:35:105%0A%20%20%20%20at%20r%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:7:302)%0A%20%20%20%20at%20g%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:34:456)%0A%20%20%20%20at%20Lb%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:38:184)%0A%20%20%20%20at%20d%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:17:381

我更新的控制器:

var saApp = angular.module("saApp", []);saApp.controller('numberController', function($scope) {$scope.number = {编号 1:0，数字2:0，sumIt:函数(){var numberObject;numberObject = $scope.number;返回 parseInt(numberObject.number1) + parseInt(numberObject.number2);}};});

我更新的 HTML:

<头><script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script><script src="js/controllers.js"/><身体><div ng-app = "saApp" ng-controller="numberController"><input type = "text" ng-model = "number.number1" placeholder = "在此处输入数字"><input type = "text" ng-model = "number.number2" placeholder = "在此处输入另一个数字">{{number.number1}} + {{number.number2}} = {{number.sumIt()}}

</html>

解决方案

您需要先将您的应用程序与您的 JS 文件链接起来.将您的标签更改为并更改您的controllers.js

如果您右键单击鼠标然后单击检查元素，也会找到控制台.

Forgive me if my question is too basic. I am learning AngularJS's controllers.

This is the project structure.

This is my html:

<!doctype html>
<html ng-app>

<head>
    <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script>
    <script src="js/controllers.js" />
</head>

<body>

<div ng-controller="numberController">
<input type = "text" ng-model = "number.number1" placeholder = "Enter a number here">

<input type = "text" ng-model = "number.number2" placeholder = "Enter another number here">
{{number.number1}} + {{number.number2}} = {{number.sumIt()}}

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

This is my controller:

function numberController($scope) {
    $scope.number = {
        number1: 0,
        number2: 0,

        sumIt: function() {
            var numberObject;
            numberObject = $scope.number;
            return parseInt(numberObject.number1) + parseInt(numberObject.number2);
        }
    };
}

The web page doesn't even load.

Where have I gone wrong?

Edit:

The error that I get: I get this error: https://docs.angularjs.org/error/$injector/modulerr?p0=sa-app&p1=Error:%20%5B$injector:nomod%5D%20http:%2F%2Ferrors.angularjs.org%2F1.3.3%2F$injector%2Fnomod%3Fp0%3Dsa-app%0A%20%20%20%20at%20Error%20(native)%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:6:416%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:366%0A%20%20%20%20at%20a%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:7)%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:21:250%0A%20%20%20%20at%20https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:35:105%0A%20%20%20%20at%20r%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:7:302)%0A%20%20%20%20at%20g%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:34:456)%0A%20%20%20%20at%20Lb%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:38:184)%0A%20%20%20%20at%20d%20(https:%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.3%2Fangular.min.js:17:381

My updated controller:

var saApp = angular.module("saApp", []);

saApp.controller('numberController', function($scope) {
    $scope.number = {
        number1: 0,
        number2: 0,
        sumIt: function() {
            var numberObject;
            numberObject = $scope.number;
            return parseInt(numberObject.number1) +      parseInt(numberObject.number2);
        }
    };
});

My updated HTML:

<!doctype html>
<html>

<head>
    <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script>
    <script src="js/controllers.js" />
</head>

<body>

<div ng-app = "saApp" ng-controller="numberController">
<input type = "text" ng-model = "number.number1" placeholder = "Enter a number here">

<input type = "text" ng-model = "number.number2" placeholder = "Enter another number here">
{{number.number1}} + {{number.number2}} = {{number.sumIt()}}

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

解决方案

You need to link your application with your JS file first.Change your tag toAnd change your controllers.js

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.number = {
        number1: 0,
        number2: 0,
        sumIt: function() {
            var numberObject;
            numberObject = $scope.number;
            return parseInt(numberObject.number1) +      parseInt(numberObject.number2);
        }
    };
});
</script>

Also the console is found if you right click on your mouse then click on Inspect element.
