Question

我是角度新手使用ng-options在下拉列表中显示值。我在一个表单中共有4个下拉列表。如果我先选择下拉列表的值然后转到第二个下拉菜单以选择任何值价值然后首先下降的价值将消失。同样的事情发生第三和第四。最后只有第四次下拉选择的价值我可以看到。在成功形式上我想显示弹出窗口。下面是我的下拉列表和脚本代码。

<select ng-model="empInfo" ng-options="emp.candidate_name for emp in names4" class="span2">
</select>                       

<select ng-model="empInfo" ng-options="emp.company_name for emp in names" class="span2">
</select>                       

<select ng-model="empInfo" ng-options="emp.designation_type for emp in names1" class="span2">                                           
</select>


var app = angular.module('myApp', ['720kb.datepicker']);
app.controller('MyController', function($scope, $http) {
    $http.get("http://www.adhr.adnacgroup.com/ADHRM/companyJson.php")
    .then(function(response) {
        $scope.names = $scope.names = response.data.service;
    });

    $http.get("http://www.adhr.adnacgroup.com/ADHRM/designationJson.php")
    .then(function(response) {
        $scope.names1 = $scope.names1 = response.data.service;
    });

    $http.get("http://www.adhr.adnacgroup.com/ADHRM/finalCandidatesJson.php")
    .then(function(response) {
        $scope.names4 = $scope.names4 = response.data.service;
    });

    $scope.insertInfo = function(info) {
        $http.post('addconfirmation.php?confirmation=',{
            "referal_code":info.referal_code,
            "candidate_id":info.candidate_id,
            "company_id":info.company_id,
            "designation_type_id":info.designation_type_id,
            "address":info.address,
            "joiningdate":info.joiningdate,
        }).success(function(data1) {
            if (data1 == true) 
            {
                getInfo();          
                $('#empForm').css('display', 'none');
            }
        });
}

您必须在每个下拉列表中指定不同的scope。在每个ng-model标记上使用相同的select，然后一个覆盖另一个。

e.g。：

<select  ng-model="empInfo1" ng-options="emp.company_name for emp in names">
<select  ng-model="empInfo2" ng-options="emp.company_name for emp in names">

多个ng-options下拉列表无法正常工作？
