使用ng-repeat从2个不同的JSON文件中提取数据 [英] Using ng-repeat to pull data from 2 different JSON files
问题描述
我没有收到错误,但无法获取我的数据进行呈现。我的结构很简单,就是一个文件夹中的json文件,另一个文件夹中的视图,另一个中的脚本/控制器。简单地使用控制器来完成工作,因为它是一个简单的小工具。任何想法可能导致这失败,因为我没有得到错误,我相信我的映射是正确的。
我的代码:
更新视图在这里:
< div class =col-md-5 propDtlstyle =padding:10px; display:block; ng-repeat =项目中的项目>
< div class =listImgstyle =float:left;>
< img src =http://placehold.it/200x200style =display:block;>
< / div>
< div class =propTxtstyle =margin-left:220px; padding:10px 0px 10px 0px;>
< p style =font-size:22px; color:blue;> {{item.address}}< / p>
< p style =font-size:22px; color:blue;> {{item.address}}< / p>
< p style =font-size:26px; color:black;> {{item.cost}}< / p>
< ul>
< li> {{item.beds}}< / li>
< li> {{item.baths}}< / li>
< li> {{item.sq_ft}}< / li>
< / ul>
< / div>
< / div>
原始视图:
< div class =containerng-controller =MainCtrl>

< div class =listingsFilter>
< a href =class =btn btn-md btn-primary> Price< / a>

< / div>
< div class =properties col-md-12style =margin-top:10px;>
< div class =col-md-5 propDtlstyle =padding:10px; display:block; ng-repeat =项目中的项目>
< div class =listImgstyle =float:left;>
< img src =http://placehold.it/200x200style =display:block;>
< / div>
< div class =propTxtstyle =margin-left:220px; padding:10px 0px 10px 0px;>

< li> {{item.value.sq_ft}}< / li>
< / ul>
< / div>
< / div>

我的管制员:
'use strict';
angular.module('zillowTestApp')
.controller('MainCtrl',['$ scope','$ http','$ filter',
function($ scope,$ http ,$ filter){
$ scope.items = [];
$ http.get('#/ batmanReality.json')。then(function(response){
angular.forEach(response.data .__ BATMAN_DATA__,function(value,key){
$ scope.items.push({
address:key,
cost:value.cost ,

sq_ft:value.sq_ft
});
})
});
$ b $ http.get('#/ supermanReality.json')。then(function(response){
angular.forEach(response.data .__ SUPERMAN_DATA__,function(value,key){
$ scope.items.push({

}]);
以及2个JSON文件及其对象和属性。

};
正如您所看到的,我将ng-repeat与item in item一起引用并构造了http。用这个对象来抓住这种方式。请注意?
请检查您的JSON。BatmanReality.json

I am not getting an errors, but cannot get my data to render. My structure is simple in that json files in one folder, views in another, scripts/controllers in another. Simply using the controller to do the work since it is a straight forward widget. Any ideas on what may be causing this to fail as I am not getting errors and I believe my mapping is correct.
My code:
updated view here:
<div class="col-md-5 propDtl" style="padding: 10px; display: block;" ng-repeat="item in items">
<div class="listImg" style="float: left;">
<img src="http://placehold.it/200x200" style="display: block;">
</div>
<div class="propTxt" style="margin-left: 220px; padding: 10px 0px 10px 0px;">
<p style="font-size: 22px; color: blue;">{{ item.address }}</p>
<p style="font-size: 22px; color: blue;">{{ item.address }}</p>
<p style="font-size: 26px; color: black;">{{ item.cost }}</p>
<ul>
<li>{{ item.beds }}</li>
<li>{{ item.baths }}</li>
<li>{{ item.sq_ft }}</li>
</ul>
</div>
</div>
original view:
<div class="container" ng-controller="MainCtrl">

<div class="listingsFilter">

<li>{{ item.value.baths }}</li>
<li>{{ item.value.sq_ft }}</li>
</ul>
</div>
</div>
</div>
</div>
my controller:
'use strict';
angular.module('zillowTestApp')
.controller('MainCtrl', ['$scope', '$http', '$filter',
function ($scope, $http, $filter) {
$scope.items = [];
$http.get('#/batmanReality.json').then(function(response){
angular.forEach(response.data.__BATMAN_DATA__, function(value,key){
$scope.items.push({
address: key,
cost: value.cost,
beds: value.beds,
baths: value.baths,
sq_ft: value.sq_ft
});
})
});
$http.get('#/supermanReality.json').then(function(response){
angular.forEach(response.data.__SUPERMAN_DATA__, function(value,key){
$scope.items.push({
address: value.address,
price: value.cost,
beds: value.beds,
baths: value.baths,
sq_ft: value.sq_ft
});
})
});
}]);
And the 2 JSON files with their objects and properties.

};
As you can see, I reference ng-repeat with "item in items" and structured the http.get to grab that way with the object. Ideas please?
Please check your JSON. Think so JSON is not valid.
