Angular Js，每次值增加时隐藏一个按钮

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>

<button ng-show="showButton">按钮</button>

<script>
  var app = angular.module('myApp', []);
  app.controller('myCtrl', function($scope) {
    $scope.value = 0; // 初始化变量值
    $scope.showButton = true; // 控制按钮的显示和隐藏

    $scope.incrementValue = function() {
      $scope.value++; // 每次点击按钮，增加变量的值
      if ($scope.value >= 5) {
        $scope.showButton = false; // 当变量值达到5时，隐藏按钮
      }
    }
  });
</script>

<div ng-app="myApp" ng-controller="myCtrl">
  <button ng-click="incrementValue()">增加值</button>
</div>
