Question

我正试图从Json数据中获取，但它对我不起作用。我不确定我做错了什么。

Angular Ajax API调用：

<script>
    function PostsCtrlAjax($scope, $http) {
        $http({
            method: 'POST',
            url: 'js/posts.json'
        }).success(function(data) {
            $scope.posts = data.deals;; // response data 
        });
    }
</script>

HTML数据绑定

<div id="ng-app" ng-app ng-controller="PostsCtrlAjax">
    <div ng-repeat="post in posts">
         <h2>
    <a href='{{post.url}}'>{{post.title}}</a>
    </h2>

        <div class='time'>{{post.time}} - {{post.author}}</div>
        <p>{{post.description}}</p>
        <img ng-src="{{post.banner}}" />
    </div>
</div>

Posts.json：

{
   "result":"SUCCESS",
   "resultMessage":"",
   "deals":[
      {
         "title":"Multiple Ajax Image Upload without Refreshing Page using Jquery.",
         "url":"http://www.9lessons.info/2013/08/multiple-ajax-image-upload-refreshing.html",

我想从json文件标题，网址，横幅等获取。但我没有从我的json文件中获取任何数据。我怎么能这样做？

Answer 1

您的JSON与教程不同，因此，您不应期望代码能够正常工作。你需要改变它。你试过这个吗？

<script>
  function PostsCtrlAjax($scope, $http) {
    $http({method: 'POST', url: 'js/posts.json'}).success(function(data) {
      $scope.posts = data.deals; // response data 
    });
  }
</script>

Answer 2

您的JSON无效。对于buyDealUrl的每个成员，deals属性的值后面有一个尾随逗号。在最后一个deals对象之后，您还有一个尾随逗号。由于我们还没有看到你的代码，所以不可能知道这些是否是它不起作用的唯一原因，但这当然可能就是它。

删除这些逗号会为您提供有效的JSON：

{
    "result": "SUCCESS",
    "resultMessage": "",
    "deals": [
        {
            "id": "1001878",
            "title": "Cotton candy muffin danish applicake. Pie jujubes icing sesame snaps marshmallow tart. ",
            "description": "Halvah candy canes chupa chups toffee dessert jujubes wafer pie marshmallow.",
            "howToUse": null,
            "city": "",
            "provider": "Yelp",
            "realPriceWithSymbol": "530 EURO",
            "dealPriceWithSymbol": "199 EURO",
            "buyDealUrl": "http://www.example.com.com/satin-al/1001878/"
        },
        {
            "id": "100343",
            "title": "Cotton candy muffin danish applicake. Pie jujubes icing sesame snaps marshmallow tart. ",
            "description": "Halvah candy canes chupa chups toffee dessert jujubes wafer pie marshmallow.",
            "howToUse": null,
            "city": "",
            "provider": "Yelp",
            "realPriceWithSymbol": "530 EURO",
            "dealPriceWithSymbol": "199 EURO",
            "buyDealUrl": "http://www.example.com.com/satin-al/100343"
        }
    ],
    "total": 1207
}

<script>
  function PostsCtrlAjax($scope, $http) {
    $http({method: 'POST', url: 'js/posts.json', dataType:"json", contentType:"application/json; charset=utf-8"}).then(function successCallback(data) {
      $scope.posts = data.data.deals; // response data 
    });
  }
</script>
