在項目中遇到表單似的頁面，需要進行增加一行和減少一行的操作，例如：

這里寫圖片描述

要實現可以選中商品，以及對商品的信息列表進行顯示與否的操作

html代碼如下：

<div class="chanpinxiangqing"> <div class="item item-divider">產品明細</div> <div class="chanpinxiangqing" ng-repeat="master in masters">  <div class="item item-divider">   <div class="" ng-click="selectorOne($index)" style="display: inline-block;width: 50%;">    <div class="chioceHook sPround">     <div class="ion-checkmark-round ng-hide" ng-show="master.checked" style=""></div>    </div>    <span style="margin-left:20px;">產品</span>   </div>   <div ng-click="upOrdown($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"><!--產品類型-->{{master.chanpinType}}</span>    <select class="" ng-model="myselectType" mobiscroll-select="settings" mobiscroll-instance="demo">     <option value="0">請選擇</option>     <option value="1">中藥</option>     <option value="2">西藥</option>    </select>   </li>   <li class="row">    <span class="col-xs-5"><!--產品名稱-->{{master.chanpinName}}</span>    <select class="" ng-model="myselectName" placeholder="請選擇" mobiscroll-select="settings" mobiscroll-instance="demo">     <option value="0">請選擇</option>     <option value="1">注射劑</option>     <option value="2">麻醉劑</option>    </select>   </li>   <li class="row">    <span class="col-xs-5"><!--規格-->{{master.guige}}</span>    <select class="" ng-model="myselectGuige" placeholder="請選擇" mobiscroll-select="settings" mobiscroll-instance="demo">     <option value="0">請選擇</option>     <option value="1">10ml</option>     <option value="2">20ml</option>    </select>   </li>   <li class="row">    <span class="col-xs-5"><!--單位-->{{master.danwei}}</span>    <input type="text" name="" class="col-xs-8" value="" />   </li>   <li class="row">    <span class="col-xs-5"><!--數量-->{{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"><!--單價（元）-->{{master.price}}</span>    <input type="text" name="" class="col-xs-8" value="" />   </li>   <li class="row">    <span class="col-xs-5"><!--總價-->{{master.total}}</span>    <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>合計發貨總額：</span></div><div class=""> <div class="btnadd" ng-click="add()">增加</div> <div class="btndel" ng-click="delete()">刪除</div></div>

js代碼：

//控制器及服務等.controller('fhShenQingAddCtrl', function($scope, CONFIG, $ionicSlideBoxDelegate, $rootScope, $http, $ionicPopup, faHuoService, $timeout, $window, loading, tool) {//產品下的類型名稱及規格的選擇彈窗設置 $scope.settings = {  theme: 'mobiscroll',  lang: 'zh',  display: 'center',  cancelText: '取消',  setText: '確定',  onBeforeClose: function(event, inst) {   if(event.button == "set") {    $scope.startdate = event.valueText;//獲取選擇日期    console.log($scope.startdate)   } else if(event.button == "cancel") {    console.log("取消")   }  } }; //增加 $scope.masters= [{'chanpinType':'產品類型',     'chanpinName':'產品名稱',     'guige':'規格',     'danwei':'單位',     'num':'數量',     'price':'單價（元）',     'total':'總價',     'checked':'true',//選中切換     'updown':'true',//下拉內容顯示切換     'up':'true'//箭頭上下切換     }]; $scope.add = function() {  $scope.cope={'chanpinType':'產品類型',     'chanpinName':'產品名稱',     'guige':'規格',     'danwei':'單位',     'num':'數量',     'price':'單價（元）',     'total':'總價',     'checked':'true', //選中切換     'updown':'true', //下拉內容顯示切換     'up':'true' //箭頭上下切換     };  var bb = angular.copy($scope.cope);  $scope.masters.push(bb)   console.log($scope.masters) }; //刪除 $scope.delete = function() {  var arr = [];  angular.forEach($scope.masters,function(item,index){   if(!item.checked){    arr.push(item);        }  })  //console.log(arr)  $scope.masters = arr; }; //切換箭頭的上下指向這里寫代碼片 $scope.upOrdown = function(rowNumber){  console.log($scope.masters[rowNumber].updown)  $scope.masters[rowNumber].up = !$scope.masters[rowNumber].up;  $scope.masters[rowNumber].updown=!$scope.masters[rowNumber].updown; }; //某一行選中 $scope.selectorOne = function(rowNumber) {  console.log($scope.masters[rowNumber].checked)  $scope.masters[rowNumber].checked = !$scope.masters[rowNumber].checked; };})
