Question

我正在尝试在级联选择元素中设置模型的初始值。

所有模型都有初始值。视图是这样的：

**1)** <select id="ddN_Universitate" ng-model="CandidatInfo.ID_N_UniversitateAbsolvita" ng-change="N_FACULTATEListByN_UNIVERSITATE(CandidatInfo.ID_N_UniversitateAbsolvita)" ng-options="u.ID_ELEMENT as u.DENUMIRE for u in ListN_UniversitatiInfo">
    <option value=''>Selecteaza</option>
</select>

<br />

**2) depends on 1)**
N_Facultate {{CandidatInfo.ID_N_FacultateAbsolvita}}
<select id="ddN_Facultate" ng-model="CandidatInfo.ID_N_FacultateAbsolvita" ng-change="N_PROGRAM_DE_STUDIUListByN_FACULTATE(CandidatInfo.ID_N_FacultateAbsolvita)" ng-options="f.ID_ELEMENT as f.DENUMIRE for f in ListN_FacultatiInfo">
    <option value=''>Selecteaza</option>
</select>

<br />

**3) depends on 2)**
N_Program {{CandidatInfo.ID_N_ProgramStudiuAbsolvit}}
<select id="ddN_ProgramStudiu" ng-model="CandidatInfo.ID_N_ProgramStudiuAbsolvit" ng-options="p.ID_ELEMENT as p.DenumireCompletaRMU for p in ListN_PROGRAM_DE_STUDIUInfo">
    <option value=''>Selecteaza</option>
</select>

对于id =“ddN_Universitate”，设置了值，但对于以下选择，未设置模型中的值，因为它们依赖于调用“ng-change”事件处理程序。

控制器是这样的：

$scope.LoadUniversitati = function () {

    factoryRMU.callGetService("N_UNIVERSITATE/N_UNIVERSITATEListByAnUniversitar?iD_AnUniv=" + $id_anuniv)
        .then(function (response) {
            var fullResult = angular.fromJson(response);
            //var CandidatInfo = JSON.parse(fullResult.data);
            $scope.ListN_UniversitatiInfo = fullResult.data;
        },
            function (data) {
                console.log("Unknown error occurred calling N_UNIVERSITATEListByAnUniversitar");
                console.log(data);
            });
};

$scope.N_FACULTATEListByN_UNIVERSITATE = function (iD_UNIVERSITATE) {

    factoryRMU.callGetService("N_FACULTATE/N_FACULTATEListByN_UNIVERSITATE?iD_UNIVERSITATE="+ iD_UNIVERSITATE + "&iD_AnUniv=" + $id_anuniv)
        .then(function (response) {
            var fullResult = angular.fromJson(response);
            //var CandidatInfo = JSON.parse(fullResult.data);
            $scope.ListN_FacultatiInfo = fullResult.data;
        },
            function (data) {
                console.log("Unknown error occurred calling N_FACULTATEListByN_UNIVERSITATE");
                console.log(data);
            });
};


$scope.N_PROGRAM_DE_STUDIUListByN_FACULTATE = function (iD_Facultate) {

    factoryRMU.callGetService("N_PROGRAM_DE_STUDIU/N_PROGRAM_DE_STUDIUListByN_FACULTATE?iD_ELEMENT=" + iD_Facultate + "&iD_AnUniv=" + $id_anuniv)
        .then(function (response) {
            var fullResult = angular.fromJson(response);
            //var CandidatInfo = JSON.parse(fullResult.data);
            $scope.ListN_PROGRAM_DE_STUDIUInfo = fullResult.data;
        },
            function (data) {
                console.log("Unknown error occurred calling N_PROGRAM_DE_STUDIUListByN_FACULTATE");
                console.log(data);
            });
};


$scope.LoadUniversitati();

那么，有可能吗？

谢谢。

试试这个

<select id="ddN_Universitate" ng-model="CandidatInfo.ID_N_UniversitateAbsolvita" ng-change="N_FACULTATEListByN_UNIVERSITATE(CandidatInfo.ID_N_UniversitateAbsolvita)">
  <option value=''>Selecteaza</option>
  <option ng-repeat="u in ListN_UniversitatiInfo" value="{{u.ID_ELEMENT}}">{{u.ELEMENT_LABEL}}</option>
</select>

在级联上设置初始值在Angular中选择
