AngularJS(1.5.8)-如何直接从获取json对象的控制器中填充选择选项列表? [英] AngularJS (1.5.8) - How do I populate a select option list directly from within controller that gets a json object?

问题描述

我有一个AngularJS应用，我想从JSON结果中填充选择下拉列表.

I have an AngularJS app that I want to populate a select drop down list from a JSON result.

控制器代码获取json，但如何填充$ scope.states.

The controller code gets the json but how do I populate the $scope.states.

我的下拉菜单在提取时仍然为空，页面的分辨率未呈现.

My drop down remains empty on the fetch and the res of the page does not render.

$ scope.accountAddresses是带有各种数据的JSON容器.我只关心shippingState键.

$scope.accountAddresses is a JSON container with various data. My concern is only for the shippingState key.

HTML代码

<select name="shippingState" id="shippingState"  ng-model="accountAddresses.shippingState"  class="state form-control" size="1">

控制器JSON提取代码

 $http.get( serviceBase + 'Assets/us-states.json').success(function(d){
            $scope.states = d;
      });

我尝试了ng-repeat="state in $scope.states"，但是下拉菜单中没有任何数据(状态缩写).

I tried ng-repeat="state in $scope.states" but I do not get any data (state abbreviations) in the drop down.

JSON示例数据

[
    {
        "name": "Alabama",
        "abbreviation": "AL"
    },
    {
        "name": "Alaska",
        "abbreviation": "AK"
    }]

如何使人口群体像以下html选项代码一样工作?

How do I get the population to work like the following html code of options?

 <option value="AK">AK</option>
<option value="AL">AL</option>

编辑

使用以下代码

 <select name="shippingState" id="shippingState"  ng-model="accountAddresses.shippingState"  ng-options ="s.abbreviation as s.name for s in states" class="state form-control" size="1">

我得到以下内容，但我需要删除字符串:"并添加标签

<option value="string:AL" label="Alabama">Alabama</option>
<option value="string:AK" label="Alaska">Alaska</option>

推荐答案

您应该使用 ng-options .

取决于您要显示的内容:

Depending on what you want to show:

<select ng-options="state as state.name for state in states track by state.abbreviation" ng-model="accountAddresses.shippingState"></select>
