javascript - Angular 无法将函数计算的数据作为 JSON 发送

Question

在表单中，我尝试将数据作为 json 发送到 php 文件，该文件是根据 Controller 中的函数正确计算的。但是，如果我尝试将此计算数据作为 json 发送， header 显示为空白对象。有人能告诉我为什么吗？

表格:

<form id="form1" post="">
    <p ng-model="result">{{add()}}</p>
    <button type="submit" class="btn btn-default" ng-click="submitting()" >Submit</button>          
</form>

Controller :

$scope.submitting = function(){
    var request = $http({ method: "post", url: "php/store.php", 
    data: {"Answer": $scope.result} });
    request.success(function (data) { 
        //alert("Successfully data entered! "); 
    });
}


$scope.add = function(){ 
    var a = 10; var b = 20; var c = a + b;
    return c;
}

问题出在你的 Controller 内部，应该是这样的

表格:

<form id="form1" post="">
    <p >{{add()}}</p>
    <button type="submit" class="btn btn-default" ng-click="submitting()" >Submit</button>          
</form>

Controller :

$scope.submitting = function(){
    var request = $http({ method: "post", url: "php/store.php", 
    data: {"Answer": $scope.add()} });
    request.success(function (data) { 
        //alert("Successfully data entered! "); 
    });
}


$scope.add = function(){ 
    var a = 10; var b = 20; var c = a + b;
    return c;
}
