在更改年份值时,我想更改Make下拉的选项,但不知道如何更新其他控件的选项。
下面是我的柱塞形式。https://plnkr.co/edit/aV65Nab9U9I6YlK2g4sY?p=preview api.php
是服务器响应,这些选项应该显示在Make下拉菜单中,以更改年份。
autoQuoteCtrl.js
$scope.updateMakeList = function(){
}
index . html
<div class="row">
<div class="form-group">
<label class="col-sm-5 control-label" for="PC">{{questions[$state.current.name].VehicleYear.QuestionData._text}}</label>
<div class="col-sm-6">
<select ng-change="updateMakeList" custom-required="true" ng-options="ans._value as ans._promptText for ans in questions[$state.current.name].VehicleYear.QuestionData._answerOptions" ng-model="answers.VehicleYear" ng-required="queObj._required" class="form-control {{queObj._pageAttributes.cssclass}}" name="{{questions[$state.current.name].VehicleYear.QuestionData._attributeName}}" id="{{questions[$state.current.name].VehicleYear.QuestionData._attributeName}}" data-que-obj="questions[$state.current.name].VehicleYear.QuestionData" select-control-dir setMake custom-required></select>
</div>
</div>
<span class="form-error" ng-show="submitted && DTOstep1.VehicleYear.$error.required">This field is required.</span>
</div>
你需要把这个函数放到你的控制器中-
$scope.updateMakeList = function(name)
{
// Your logic to change value in Make dropdown
$scope.questions[name].VehicleMake.QuestionData._answerOptions = [{'_value':"test",'_promptText':"Test"}];
}
更新你的HTML(年份选择框)-
<div class="form-group">
<label class="col-sm-5 control-label" for="PC">{{questions[$state.current.name].VehicleYear.QuestionData._text}}</label>
<div class="col-sm-6">
<select ng-change="updateMakeList($state.current.name)" custom-required="true" ng-options="ans._value as ans._promptText for ans in questions[$state.current.name].VehicleYear.QuestionData._answerOptions" ng-model="answers.VehicleYear" ng-required="queObj._required" class="form-control {{queObj._pageAttributes.cssclass}}" name="{{questions[$state.current.name].VehicleYear.QuestionData._attributeName}}" id="{{questions[$state.current.name].VehicleYear.QuestionData._attributeName}}" data-que-obj="questions[$state.current.name].VehicleYear.QuestionData" select-control-dir setMake custom-required></select>
</div>
