我要如何使用Angularjs JSON数据的特定值 [英] How do i get the specific value from json data using Angularjs

问题描述

我是新来AngularJs。我想基于搜索的关键字从JSON获取值并显示相关的数据。

i am new to AngularJs. I am trying to get the values from json based on search key word and displaying that related data.

下面是我的JSON格式

Below is my json format

{"abc":[  
    { "url":"abc.json"}  
 ],  
 "bbc":[   
    {"url":"bbc.json"}  
 ]
}

我正在用比较输入的搜索词的关键。如果匹配的话，我需要加载单独的JSON这是关系到找到钥匙。我能够搜索词与主要的比较，但是当我试图获得的价值正在逐渐像URL = abc.json总价值，而不是这个，我只得到abc.json。我的控制器code是如下：

i am comparing the key with entered search word. If it matches then i need to load the separate json which is related to found key. I am able to compare the search word with key, but when i am trying to get the value am getting total value like url=abc.json, instead of this i've to get only abc.json. My controller code is as follows

function getDetailsController($scope,$http) {  
    $scope.search = function() {  
        $http.get("searchInfo.json").success(function(response) {  
            angular.forEach(response, function(value, key) {  
                 if(angular.equals(key, $scope.searchText)){  
                    $scope.url = value;  
                    $http.get(url).success(function(response) {  
                        $scope.details = response;  
                    });  

                }
            });

        });
    };
}

我曾尝试在不同势方法，但我没能拿到价值。你能帮我在此。

I have tried in diffrent ways but i was not able to get the value. Could you please help me on this.

推荐答案

在您的JSON，ABC'：是一个关​​键，其对应值为

In your JSON, '"abc"': is a key, and its corresponding value is

[{ "url":"abc.json"}]

这是包含单个对象的数组，包含一个键的对象：URL

That is an array containing a single object, the object containing a single key: "url".

因此​​，访问此网址，您只需

So, to access this URL, you simply need

value[0].url

这结构很奇怪，但。我真的不明白包装内部数组对象的点。

This structure is quite strange though. I don't really understand the point of wrapping the object inside an array.
