Javascript 如何从AngularJS中的太数组json获取信息

我有一个JSON文件，它有两个数组，其中包含一些我想在AngularJS网站上访问的数据。现在我只想从2个数组中得到一个对象

JSON数据

[

    "DailyForecasts": [
      {

          "weatherCode": "3100"
        }
      }
    ]
  }
]

控制器代码

 app.controller('Hillahctlr', function($scope, $http, wind, arrivecss, windname, icons) {
     $scope.wind_dir = wind;
     $scope.icons = icons;
     $scope.arrivecss = arrivecss;
     $scope.windname = windname;
     var service_url = "/key=e88d1560-a740-102c-bafd-001321203584&units=m&locale=ar&cb=JSON_CALLBACK";
     $http.jsonp(service_url)
         .success(
             function(data) {
                 console.log(data);
                 yData = data.HourlyForecasts;
                 $scope.ali = [];
                 for (var i = 0; i < 9; i++)
                 {
                     $scope.ali[i] = {
                         dayes: yData[i].temp,
                     };
                 }
             })
 })
 }

app.controller（'Hillahctlr'，函数（$scope，$http，wind，arrivecss，windname，icons）{
$scope.wind_dir=风；
$scope.icons=图标；
$scope.arrivecss=arrivecss；
$scope.windname=windname；
var service_url=“/key=e88d1560-a740-102c-bafd-001321203584&units=m&locale=ar&cb=JSON_回调”；
$http.jsonp（服务url）
.成功(
功能（数据）{
控制台日志（数据）；
yData=data.hourlyforecast；
$scope.ali=[]；
对于（变量i=0；i<9；i++）
{
$scope.ali[i]={
dayes:yData[i].温度，
};
}
})
})
}

并使用ng repeat在该数组中循环，但这对我不起作用，这是代码：

HTML

<div class="ForecastArea-Day Last weatherteble" ng-repeat="alis in dayes">
   {{alis.dayes}}
</div>

{{alis.dayes}

我收到此错误：

错误：未定义yData

请提供帮助？

尝试此操作

var alis = [];

 alis = {dayes: yData[i].temp,};
 $scope.ali = ali;

<div class="ForecastArea-Day Last weatherteble" ng-repeat="alis in ali.dayes"> 
{{alis.day}}
</div>

var-alis=[]；
alis={dayes:yData[i].temp，}；
$scope.ali=ali；
{{alis.day}

使用

yData=data[0]。小时预测。JSON以
[{“DailyForecast”：[
开头，这意味着它是一个对象数组


工作很好谢谢，对象日在
HourlyForecasts
当运行get
yData[i]时，日期
是
未定义的

看到我的短代码了吗

yday = data[0].DailyForecasts;
$scope.daily = [];
for(var i=0; i<9; i++) {
    $scope.daily[i] = {maxTemp: yData[i].maxTemp,
                       minTemp: yData[i].minTemp,
                       validDate: yData[i].validDate,
                       icon: yData[i]day.icon, };
}

还要确保将
yday
声明为变量：

 //yday = data[0].DailyForecasts;
 var yday = data[0].DailyForecasts;

如果没有
var
声明，它将处理全局命名空间。
您在哪里定义了
HourlyForecasts
？是的，请参见更新，数据。HourlyForecasts您的数据没有定义HourlyForecasts您可以通过console在浏览器上登录数据对象吗。log（数据）要检查datayData的正确结构是否应声明为$scope.yData=data.HourlyForecasts；或var-yData=data.HourlyForecasts；
错误：我未定义
工作正常，谢谢，当我尝试这样做时，对象
day
在
HourlyForecasts
.HourlyForecasts.day；

运行时获取

yData[i]。day未定义

请参阅我的简短代码

yday=data[0]。DailyForecasts；$scope.daily=[]；for（var i=0；i
 //yday = data[0].DailyForecasts;
 var yday = data[0].DailyForecasts;
