嗨我有一个角度js /离子项目正在调用Yahoo!财务webservice正在返回以下json ..我试图在我的index.html上显示它但是它无法呈现JSON数据我怎样才能在我的角度中引用"价格" :" 34.849998"来自JSON?
我尝试使用{{fiveDay.list [0] .meta [0] .type}}进行拉动工作
index.html(
{{fiveDay.list [0] .meta [0] .type}}
是我需要正确的JSON参考的地方)
$order

app.js:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

我尝试阅读的JSON文件如下:
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
var app = angular.module('starter', ['ionic'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
app.controller('MainController', ['$scope', 'stocks', function($scope, stocks) {
//$scope.ticker = 'Bad Guy KUTA';
stocks.success(function(data) {
$scope.fiveDay = data;
});
}]);
app.factory('stocks', ['$http', function($http) {
return $http.get('http://finance.yahoo.com/webservice/v1/symbols/YHOO/quote?format=json')
.success(function(data) {
return data;
})
.error(function(err) {
return err;
});
}]);
答案 0 :(得分:2)
您正在拨打.success()
两次:
return $http.get('http://finance.yahoo.com/webservice/v1/symbols/YHOO/quote?format=json')
.success(function(data) {
return data;
})
...
stocks.success(function(data) {
$scope.stockVariable = data;
});
我建议你回复工厂的承诺:
return $http.get('...');
...
stocks.then(function(data) { $scope.stockVariable = data; });
编辑:
list
和meta
都不是数组:
{
"list":{
"meta":{
"type":"resource-list",
"start":0,
"count":1
},
"resources":[
{
"resource":{
"classname":"Quote",
"fields":{
"name":"Yahoo! Inc.",
"price":"34.849998",
"symbol":"YHOO",
"ts":"1449608400",
"type":"equity",
"utctime":"2015-12-08T21:00:00+0000",
"volume":"19852579"
}
}
}
]
}
}
只有方括号的值是数组,这意味着只有resources
是一个数组。因此,要访问price
,您需要执行以下操作:
$scope.prices = fiveDay.list.resources
.map(function(item) {
return item.resource.fields.price;
});
或者,如果你真的只得到一个:
$scope.price = fiveDay.list.resources[0].resource.fields.price;
