Angular找不到变量:数据

问题描述

我已经完成了我的第一个有角度的应用程序.调用函数时出现错误.这是我的JSON的代码段:

I've already done with my first angular app. I have an error while calling a function.Here is a snippet of my JSON:

{

  "variantA": {
    "sumInsuredThirty": [
      {
        "dayFrom": 1,
        "dayTo": 3,
        "tarif": 2
      }, ...

我通过以下方式得到它

  $http.get("/CalculatorMed/JSON/rates.json/").then(function(data) {
        $scope.rates = data.data;
        });

现在，我正在尝试获取tarif:

Now, I'm trying to get the tarif:

$scope.getBaseTarif = function () {
        var baseTarif = 0;
        if (data.pickedOptions.variantA === true && data.pickedOptions.sumInsured === 30000) {
            for (var i = 0; i < rates.variantA.sumInsuredThirty.lenght; i++) {
                if (data.pickedOptions.days >= rates.variantA.sumInsuredThirty[ i ].dayFrom && data.pickedOptions.days <= rates.variantA.sumInsuredThirty[ i ].dayTo) {
                    baseTarif = rates.variantA.sumInsuredThirty[ i ].tarif;
                    return baseTarif;
                }
            }
        }
      };

我有一个错误:

错误:找不到变量:数据getBaseTarif @ http://localhost:63342/CalculatorMed/controller/calculator.js:34:17 fn

Error: Can't find variable: datagetBaseTarif@http://localhost:63342/CalculatorMed/controller/calculator.js:34:17fn

非常感谢！

推荐答案

数据不能在外部访问，应该是$ scope.rates，

data cannot be access outside, it should be $scope.rates,

 if ($scope.rates.pickedOptions.variantA === true && $scope.rates.pickedOptions.sumInsured === 30000) {
            for (var i = 0; i < rates.variantA.sumInsuredThirty.length; i++) {
                if ($scope.rates.pickedOptions.days >= rates.variantA.sumInsuredThirty[i].dayFrom && $scope.rates.pickedOptions.days <= rates.variantA.sumInsuredThirty[i].dayTo) {
                    baseTarif = rates.variantA.sumInsuredThirty[i].tarif;
                    return baseTarif;
                }
            }
        }
