how to use ng-options and ng-select with json

Question

Can somebody explain how to use ng-options when I have below json:

{
"key1":
    {
        "name":"test1",
        "code":"horizontal",
        "fields":[
            {
                "type":"email"
            },
            {
                "type":"text"
            }
            ]
    },
"key2":
    {
        "name":"test2",
        "code":"vertical",
        "fields":[
            {
                "type":"emai"
            },
            {
                "type":"text"
            }
        ]
    }
}

and then i try to create select like this

<select name="cert" id="cert" ng-options="item as item[paramm] for item in listcert track by $index"></select>

where "paramm" = $key in json.

I want to see something like this

<select>
  <option value="horizontal" label='horizontal'>test1</option>
  <option value="vertical" label='vertical'>test2</option>
</select>

I have no idea how it works. Please help...

Answer 1

Is this what you were looking for? The trick here is that your data is not in an array format

 var data = { "key1": { "name":"test1", "code":"horizontal", "fields": [{ "type":"email", },{ "type":"text", }] }, "key2": { "name":"test2", "code":"vertical", "fields": [{ "type":"emai", },{ "type":"text", }] } } angular.module("app", []) .controller("MainController", MainController); function MainController() { var vm = this; vm.selected = {}; vm.dataArray = []; angular.forEach(data, function(value, key) { vm.dataArray.push(value); }, data); }

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="app" ng-controller="MainController as main"> <select ng-options="value as value.code for value in main.dataArray track by value.name" ng-model="selected"></select> <h3>Selected value:</h3> <pre>{{selected | json}}</pre> </div>

Answer 2

this may suits for you

     <select>
        <option ng-repeat="(key, value) in listcert" value="{{value.code}}" >{{value.name}}</option>
</select>
