我试图在点击按钮时切换div文本.我尝试根据变量获取范围变量和toggeling classname.我在哪里弄错了

<button ng-click="toggle()">test </button>
    <div ng-class="{{state}}" >
        hello test
    </div>


function ctrl($scope) {    
    $scope.state = vis;
    $scope.toggle = function () {
      state = !state;
    };
}

 .vis{
      display:none;
}
