AngularJS ng-repeat-http.gs检索数据，但不显示 [英] AngularJS ng-repeat - http.gs retrieving data, but not displaying

问题描述

我是angular的新手，正在尝试将其集成到我的应用程序中.我正在尝试对.JSON文件使用简单的$http.get，该文件在ng-repeat

I am new to angular and trying to integrate it within my application. I am attempting to use a simple $http.get to a .JSON file, which displaying the matching contents in a ng-repeat

我得到了:

$scope.countries = [];
$http.get('/resources/data/countries-report.json').success(function(data) {
    $scope.countries = data.countries;
    // alert(JSON.stringify($scope.countries));
    console.log(data.countries);
    console.log(data.countries.population);
}).error(function(error) {
    alert('error');
});

这是我的.JSON文件:

Here's my .JSON file:

{
  "firstName"   : "Joe",
  "surName" : "Bloggs",
  "countries" : [
      { "name": "France", "population": "63.1" },
      { "name": "Span", "population": "52.3" },
      { "name": "United Kingdom", "population": "61.8" }
  ]
}

这是我的HTML:

<li ng-repeat="country in countries">
    {{country.name}} has population of {{country.population}}
</li>

在浏览器中查看时，显示的全部是:

When viewing in the browser, all that is displayed is:

• 人口
• 人口
• 人口

似乎我的代码可以看到3个国家/地区，当我在.JSON文件中添加或删除时，HTML中的列表会相应地进行修改，但是.JSON的内容未显示.

It seems as though my code can see there are 3 countries, as when i add or remove from my .JSON file, the list in the HTML modifies accordingly, however, the contents of the .JSON is not displaying.

我忘了从我的.get ??

**更新*************************

正如某些人提到的那样，我的代码似乎是正确的，我想我知道可能是什么问题.

As some have mentioned, my code seems to be correct, i think i know what the problem may be.

我的应用程序使用了Swig的HTML模板结构，该结构使用{{}}访问.JSON文件.这是否会导致与Angular混淆?

My application makes use of a HTML templating structure using Swig which accesses .JSON file using {{ }}.. Could this be causing confusion with Angular?

**更新*************************

如果我更改:

var app = angular.module("app", []);

到

var app = angular.module('app', []).config(function($interpolateProvider){
        $interpolateProvider.startSymbol('{[{').endSymbol('}]}');
    }
);

并且:

<li ng-repeat="country in countries">
     {{country.name}} has population of {{country.population}}
</li>

收件人:

<li ng-repeat="country in countries">
     {[{country.name}]} has population of {[{country.population}]}
</li>

然后显示正确的值.

推荐答案

您必须以

[
  { 
    id:1,
    ima:gh.jpg,
    data: 
    [
      {
        anotherid:1,
        my:w,
        ki:y
      }
    ]
  },
  {
    id=2,
    ima:jh.jpg
  }
]
