要实现可以选中商品，以及对商品的信息列表进行显示与否的操作

html代码如下：

<div class="chanpinxiangqing">
 <div class="item item-divider">产品明细</div>
 <div class="chanpinxiangqing" ng-repeat="master in masters">
 <div class="item item-divider">
 <div class="" ng-click="selectorOne($index)" style="display: inline-block;width: 50%;">
 <div class="chioceHook sPround">
 <div class="ion-checkmark-round ng-hide" ng-show="master.checked" style=""></div>
 </div>
 <span style="margin-left:20px;">产品</span>
 </div>
 <div ng-click="upOrdown($index);" ng-class="{true:'up',false:'upDown'}[master.updown]"></div>
 </div>
 <ul class="rzInfo" ng-show="master.up">
 <li class="row">
 <span class="col-xs-5"><!--产品类型-->{{master.chanpinType}}</span>
 <select class="" ng-model="myselectType" mobiscroll-select="settings" mobiscroll-instance="demo">
 <option value="0">请选择</option>
 <option value="1">中药</option>
 <option value="2">西药</option>
 </select>
 </li>
 <li class="row">
 <span class="col-xs-5"><!--产品名称-->{{master.chanpinName}}</span>
 <select class="" ng-model="myselectName" placeholder="请选择" mobiscroll-select="settings" mobiscroll-instance="demo">

 <option value="1">注射剂</option>
 <option value="2">麻醉剂</option>
 </select>
 </li>
 <li class="row">
 <span class="col-xs-5"><!--规格-->{{master.guige}}</span>
 <select class="" ng-model="myselectGuige" placeholder="请选择" mobiscroll-select="settings" mobiscroll-instance="demo">
 <option value="0">请选择</option>
 <option value="1">10ml</option>
 <option value="2">20ml</option>
 </select>
 </li>
 <li class="row">
 <span class="col-xs-5"><!--单位-->{{master.danwei}}</span>
 <input type="text" name="" class="col-xs-8" value="" />
 </li>
 <li class="row">
 <span class="col-xs-5"><!--数量-->{{master.num}}</span>
 <!--<b class="" contenteditable="true" ng-model="dataclean" ></b>-->
 <input type="text" name="" class="col-xs-8" value="" />
 </li>
 <li class="row">
 <span class="col-xs-5"><!--单价（元）-->{{master.price}}</span>
 <input type="text" name="" class="col-xs-8" value="" />

 <input type="text" name="" readonly class="col-xs-8" value="" />
 </li>
 </ul>
 </div>
</div>
<div class="" style="margin-top: 10px;padding:10px;text-align: right;background: #fff;"><span>合计发货总额：</span></div>
<div class="">
 <div class="btnadd" ng-click="add()">增加</div>
 <div class="btndel" ng-click="delete()">删除</div>
</div>

js代码：

//控制器及服务等
.controller('fhShenQingAddCtrl', function($scope, CONFIG, $ionicSlideBoxDelegate, $rootScope, $http, $ionicPopup, faHuoService, $timeout, $window, loading, tool) {
//产品下的类型名称及规格的选择弹窗设置
 $scope.settings = {
 theme: 'mobiscroll',
 lang: 'zh',
 display: 'center',
 cancelText: '取消',
 setText: '确定',
 onBeforeClose: function(event, inst) {
 if(event.button == "set") {
 $scope.startdate = event.valueText;//获取选择日期
 console.log($scope.startdate)
 } else if(event.button == "cancel") {
 console.log("取消")
 }
 }
 };
 //增加
 $scope.masters= [{'chanpinType':'产品类型',
 'chanpinName':'产品名称',
 'guige':'规格',
 'danwei':'单位',
 'num':'数量',
 'price':'单价（元）',
 'total':'总价',
 'checked':'true',//选中切换
 'updown':'true',//下拉内容显示切换
 'up':'true'//箭头上下切换
 }];
 $scope.add = function() {
 $scope.cope={'chanpinType':'产品类型',
 'chanpinName':'产品名称',
 'guige':'规格',
 'danwei':'单位',
 'num':'数量',
 'price':'单价（元）',
 'total':'总价',
 'checked':'true', //选中切换
 'updown':'true', //下拉内容显示切换
 'up':'true' //箭头上下切换
 };
 var bb = angular.copy($scope.cope);
 $scope.masters.push(bb) 
 console.log($scope.masters)
 };
 //删除
 $scope.delete = function() {
 var arr = [];
 angular.forEach($scope.masters,function(item,index){
 if(!item.checked){
 arr.push(item); 
 }
 })
 //console.log(arr)
 $scope.masters = arr;
 };
 //切换箭头的上下指向这里写代码片
 $scope.upOrdown = function(rowNumber){
 console.log($scope.masters[rowNumber].updown)
 $scope.masters[rowNumber].up = !$scope.masters[rowNumber].up;
 $scope.masters[rowNumber].updown=!$scope.masters[rowNumber].updown;
 };
 //某一行选中
 $scope.selectorOne = function(rowNumber) {
 console.log($scope.masters[rowNumber].checked)
 $scope.masters[rowNumber].checked = !$scope.masters[rowNumber].checked;
 };
})
