angular.js - angularjs $scope value undefined

  <form class="ui form" id="indexForm" name="indexForm" onsubmit="return false;">
    <span id="QuacorGradingValue" ng-model="fen" name="fen">6</span>
</form>

Why can’t I get it in the controller

    var updateData = {};
    alert("$scope.rates==="+$scope.fen);//undefined

//$scope is valuable

    data-ng-init='fen=6'
    

    controller:

    $scope.$watch("fen", function(){
        console.log($scope.fen);
    });

    Suppose your controller looks like this:

    module.controller('DemoController', ['$scope', function($scope) {
        $scope.fen = '';   //为其指定一个初始值,这样在html里引用时才不会因为parent scope里没有找到`fen`变量而重新创建一个
    }]);
