javascript - 将变量与 json 对象进行比较

Question

我试图将用户的选择(性别和国家/地区)与 json 对象(性别和国家/地区)进行比较。如果比较为真，则 console.log json 的性别和国家/地区的“值”。

JS:

var app = angular.module('deathApp', []);
app.controller('data', function ($scope, $http) {
    $http.get("angular/death/data.json")
        .success(function (response) {

        $scope.ages = response.fact;
        //OBTAIN THEIR DEATH AGE
        //save their gender and country
        var gender = $('select[name=gender]').val();
        var country = $('select[name=country]').val();
        console.log("GENDER:" + gender + "." + "COUNTRY:" + country);
        //get their death age

        if (gender && country === gender and country from $scope.ages) {
            console.log(this.$scope.ages['Value'])
        }

json:

{
    "fact": [
        {
            "COUNTRY": "Afghanistan",
            "SEX": "Female",
            "Value": "62"
        },
        {
            "COUNTRY": "Afghanistan",
            "SEX": "Male",
            "Value": "61"
        },
        {
            "COUNTRY": "Albania",
            "SEX": "Female",
            "Value": "76"
        },
        {
            "COUNTRY": "Albania",
            "SEX": "Male",
            "Value": "73"
        },
        {
            "COUNTRY": "Algeria",
            "SEX": "Female",
            "Value": "74"
        },
        {
            "COUNTRY": "Algeria",
            "SEX": "Male",
            "Value": "70"
        }
    ]
}

不用太担心 json 数据的连接，它工作正常。我可以很好地获取 $scope.ages 数据。

您必须映射到数据并循环遍历数组中的对象。 :

for(var i = 0; i < $scope.ages.length; i++){

 if (gender  === $scope.ages[i].SEX && country === $scope.ages[i].COUNTRY)
   {
      console.log($scope.ages[i].Value)
   }

}
