Question

我有一个有角度的应用程序，我希望将结果导入select，所以我将其作为：

HTML

<div class="col-xs-12 col-sm-6 col-md-4">
  <div class="form-group">
    <label>Register: </label>
    <select class="form-control" ng-options="item.Nombre for item in GetCatalogoPadre"></select>
    <br />
  </div>
</div>

AngularCtrl

     function cargarCatalogo() {
         apiService.get("../../api/Catalogo/GetCatalogoPadre/", null,
            function (res) {
                $scope.Catalogos = res.data; 
            }, errorCatalogo);

控制器

namespace PortalDeTransporte.Web.Controllers
{
    //[Authorize]    
    [RoutePrefix("api/Catalogo")]
    public class CatalogoRegistroController : ApiControllerBase
    {


    [System.Web.Http.AllowAnonymous]
    [System.Web.Http.HttpGet]
    [Route("GetCatalogoPadre")]

    public HttpResponseMessage GetCatalogoPadre(HttpRequestMessage request)
    {
     //some code there for get results 
    }

            return response;
        });
    }
    }

如果我尝试使用带有GET操作的邮递员获得结果，那么就会发生一些异常情况：

http://localhost:55720/api/Catalogo/GetCatalogoPadre

我得到了正确的结果：

{
        "ID": "1",
        "Codigo": "BMX",
        "Nombre": "BANAMEX",
        "Padre": 0,
        "Catalogo": "BAN"
    },
    {
        "ID": "2",
        "Codigo": "KNW",
        "Nombre": "KENWORTH",
        "Padre": 0,
        "Catalogo": "MAR"
    },

但是他们没有出现在选择列表中，有人可以在代码中查看错误吗？此致

Answer 1

应该是，

import cv2

还确保您在 <select class="form-control" ng-options="item.Nombre for item in Catalogos "></select>

上调用此功能

ng-init

<强>样本

＆＃13;

 <div class="form-group" ng-init="cargarCatalogo()">
    <label>Register: </label>
    <select class="form-control" ng-options="item.Nombre for item in Catalogos"></select>
    <br />
  </div>

＆＃13;

var myApp=angular.module('myApp',[]);
 myApp.controller('thecontroller',function($scope){
       $scope.cargarCatalogo = function (){
            $scope.catalogos = [{
        "ID": "1",
        "Codigo": "BMX",
        "Nombre": "BANAMEX",
        "Padre": 0,
        "Catalogo": "BAN"
    },
    {
        "ID": "2",
        "Codigo": "KNW",
        "Nombre": "KENWORTH",
        "Padre": 0,
        "Catalogo": "MAR"
    }];
    };
});
