Angularjs 如何在angular JS中增加和更新按钮计数器？

在这里，它实际上是递增的，一旦刷新，值从0开始

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

下载
{{count}}

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

var-app=angular.module（“myApp”，[]）；
app.controller（“myCtrl”，函数（$scope）
{
var计数=0；
$scope=计数；
})

我需要增加和更新计数器

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

提前感谢。

尝试放置

$scope.count=0在控制器中
您的代码有很多打字错误。请使用下面的代码来实现您的输出

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

        <div ng-app="myApp" ng-controller="myCtrl">
           <button ng-click="increment()">Download</button>
           <p> {{ count }} </p>
        </div>

       <script>
       var  app=angular.module("myApp",[]);
       app.controller("myCtrl",function($scope){
          $scope.count = 0;
          $scope.increment = function(){
           $scope.count = count+1;
          };
      });
 </script>

下载
{{count}}

<div ng-app="myApp" ng-controller="myCtrl">
    <button ng-click=count=count+1>Download</button>
    <p> {{ count }} </p>
</div>

<script>
var  app=angular.module("myApp",[]);
app.controller("myCtrl",function($scope)
        {
    var count=0;
    $scope=count;
        })
</script>
</body>
</html>

var-app=angular.module（“myApp”，[]）；
app.controller（“myCtrl”，函数（$scope）{
$scope.count=0；
$scope.increment=函数（）{
$scope.count=计数+1；
};
});
无效。还有其他可能的方法吗？试着输入html
