我是网络开发的新手。在提出这个问题之前,我已经完成了所有的解决方案,但我仍然遇到了一些问题......
这里我有HTML:
<div class="col-md-6">
<label class="col-sm-4 control-label agency-label" for="agency">Agency :</label>
<div class="col-sm-4">
<select id="selectAgency"
name="selectAgency"
class="selectpicker btn btn-labeled btn-start candidateAgencyPosition"
ng-init="candidate.agency = agency[0]"
ng-model="candidate.agency"
ng-options="agencies for agencies in agency">
<!--<option value="">Select Your Option</option>-->
</select>
</div>
</div>
在这里我有一个数组:
$scope.agency = ["A", "B", "C", "D"];
现在我希望在该下拉列表中有一个A作为默认值。但目前我正在获得一个空值。
$scope.candidate = {
noticePeriod: '',
ctc: '',
ectc: '',
communication: '',
agency: ''
};
这可能是重复但我遇到问题所以我问。感谢 帮助。

您应该在控制器中初始化ngModel
链接变量,而不是使用ngInit
(function(angular) {
'use strict';
angular.module('myApp', [])
.controller('Controller', ['$scope', function($scope) {
$scope.agency = ["A", "B", "C", "D"];
$scope.candidate = {
agency: $scope.agency[0]
};
}]);
})(window.angular);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="Controller">
<select ng-model="candidate.agency" ng-options="agencies for agencies in agency"></select>
</div>
</div>

删除ng-init并改为使用ng-model:
结果:
$scope.candidate = {
noticePeriod: '',
ctc: '',
ectc: '',
communication: '',
agency: 'A'
};
