我是angularjs的新手，想知道我的代码出了什么问题。我正在跟踪教程，但由于此错误而陷入困境。
index.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AngularJS</title>
<link rel="stylesheet" href="foundation.min.css">
<script src="main.js"></script>
</head>
<body>
<div ng-app="">
<div ng-controller="FirstCtrl">
<h1>{{data.message + " world"}}</h1>
<div class="{{data.message}}">
Wrap me with foundation component
</div>
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4
/angular.min.js"></script>
</body>
</html>
main.js
function FirstCtrl($scope){
$scope.data = {message: "hello"};
}
最佳答案
您必须创建一个模块，如下所示：
var app = angular.module("MyApp",[]);
app.controller("FirstCtrl",function($scope){
$scope.data = {message: "hello"};
});
<div ng-app="MyApp">
<div ng-controller="FirstCtrl">
<h1>{{data.message + " world"}}</h1>
<div class="{{data.message}}">
Wrap me with foundation component
</div>
</div>
</div>
