两种实现方式
一 ,第一种就是使用select来实现下拉框,如下
<div class="input-select" > <select ng-model="areaId" class="js-input-select-title" ng-change="queryCityByQuYu()"> <option value="--请选择区域--">--请选择区域--</option> <option ng-repeat="areaValueViewList in areaValueViewLists" ng-value="areaValueViewList.id">{{areaValueViewList.value}}</option> </select> </div> <div class="input-select"> <select ng-model="cityIds" class="js-input-select-title"> <option value="--请选择城市--">--请选择城市--</option> <option ng-repeat="platformCustomerDictionaryValue in platformCustomerDictionaryValues" value="{{platformCustomerDictionaryValue.id}}">{{platformCustomerDictionaryValue.value}}</option> </select> </div> $scope.areaId="--请选择区域--"; $scope.cityIds="--请选择城市--"; //通过区域查询对应的城市--创建时 $scope.queryCityByQuYu = function() { if($scope.areaId == undefined || $scope.areaId == "undefined" || $scope.areaId =="--请选择区域--") { return; } }
其中下拉框选中了,将会把值付给ng-model,这样就可以通过ng-change方法来实现,
回显代码,如下
<div class="input-select"> <select ng-model="upAreaId" class="js-input-select-title" ng-change="queryCityByQuYuBj()"> <option ng-repeat="areaValueViewList in areaValueViewLists" value="{{areaValueViewList.id}}" ng-selected="upAreaId=={{areaValueViewList.id}}">{{areaValueViewList.value}}</option> </select> </div> <div class="input-select"> <select ng-model="upCityId" class="js-input-select-title" > <option ng-show="upCityId==upCityIdTwo" ng-value="upCityId" ng-selected="true">{{upCityName}}</option> <option ng-repeat="cityValueViewList in cityListBj" value="{{cityValueViewList.id}}" >{{cityValueViewList.value}}</option> </select> </div> ==>upCityId==upCityIdTwo是用来显示原本的数据是否消失
