javascript - AngularJS Unknown Provider (filterProvider) 错误

Question

下面的两个脚本语句独立工作，但是当它们组合在一起时会导致错误:[$injector:unpr] Unknown provider: searchNameFilterProvider <- searchNameFilter 谁能解释为什么会这样？

第一段

Find Person: <input type="text" ng-model="myName">
    <ul ng-init="people = ['Diarmuid','Aine','Dave','Declan']">
        <li ng-repeat="person in people | filter:myName">{{ person | searchName}}</li>
    </ul>

    <script>
        var app = angular.module('myApp',[]);
        app.filter('searchName',function(){
            return function (input){
                return input + '!';
            }
        })
    </script>

第二段

<div ng-controller="myCtrl">
    <button ng-click="myFunc()">Hello World Button</button>
</div>

<script>

    var app = angular.module('myApp',[]);
    app.controller('myCtrl',function ($scope) {

        $scope.myFunc = function () {
           console.log('Hello world!');
        };
    });

</script>

<div ng-app="myApp">
    <script src="Scripts/Angular.js" type="text/javascript"></script>
    Find Person:
    <input type="text" ng-model="myName">
   <ul ng-init="people = ['Diarmuid','Aine','Dave','Declan']">
        <li ng-repeat="person in people | filter:myName">{{ person | searchName}}</li>
    </ul>
   <script>
       var app = angular.module('myApp', []);
       app.filter('searchName', function () {
           return function (input) {
                return input + '!';
           };
       });
   </script>
  <div ng-controller="myCtrl">
        <button ng-click="myFunc()">
          Hello World Button</button>
   </div>
   <script>

    var app = angular.module('myApp');
    app.controller('myCtrl', function ($scope) {

        $scope.myFunc = function () {
            console.log('Hello world!');
