Question

我有一个简单的JavaScript对象，如下所示：

$scope.obj = { "'Architect'": ["asdf","d","e","y"]};

我想在选择框中显示'Architect'的值。但是，在尝试执行ng-repeat时，单引号会让我失望。

<select>
    <option ng-repeat="row in obj['Architect']" value="{{row}}">{{row}}</option>
</select>

这不会填充选择框，它只显示一个空的选择框。我假设它将单引号解释为字符串文字，但即使我添加单引号并将其转义，它仍然无法按预期工作。我错过了什么吗？

Here is a sample plunker:

Answer 2

为什么不使用“ng-options”进行选择？锁定这个 AngularJs API: select

index.js

var app=angular.module('problemApp', []);
app.controller('validationCtrl',function($scope,$http){
    $http.get('http://localhost/Dtable_angular/ngrepeatdropdown/test.json').success(function (data) {

                $scope.testdata = data;
                console.log($scope.testdata)
        })


$scope.dataTableOpt = {
   //custom datatable options 
  // or load data through ajax call also
  "aLengthMenu": [[10, 50, 100,-1], [10, 50, 100,'All']],
  };
});

test.json

[{
        "countryId": 1,
        "name": "France - Mainland",
        "desc": "some description"
    },
    {
        "countryId": 2,
        "name": "Gibraltar",
        "desc": "some description"
    },
    {
        "countryId": 3,
        "name": "Malta",
        "desc": "some description"
    }
]
