在项目中遇到表单似的页面，需要进行增加一行和减少一行的操作，例如：
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> <div>产品明细</div> <div ng-repeat="master in masters"> <div> <div ng-click="selectorOne($index)"> <div> <div ng-show="master.checked"></div> </div> <span>产品</span> </div> <div ng-click="upOrdown($index);" ng-class="{true:'up',false:'upDown'}[master.updown]"></div> </div> <ul ng-show="master.up"> <li> <span><!--产品类型-->{{master.chanpinType}}</span> <select 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> <span><!--产品名称-->{{master.chanpinName}}</span> <select ng-model="myselectName" placeholder="请选择" mobiscroll-select="settings" mobiscroll-instance="demo"> <option value="0">请选择</option> <option value="1">注射剂</option> <option value="2">麻醉剂</option> </select> </li> <li> <span><!--规格-->{{master.guige}}</span> <select 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> <span><!--单位-->{{master.danwei}}</span> <input type="text" value="" /> </li> <li> <span><!--数量-->{{master.num}}</span> <!--<b contenteditable="true" ng-model="dataclean" ></b>--> <input type="text" value="" /> </li> <li> <span><!--单价（元）-->{{master.price}}</span> <input type="text" value="" /> </li> <li> <span><!--总价-->{{master.total}}</span> <input type="text" readonly value="" /> </li> </ul> </div> </div> <div><span>合计发货总额：</span></div> <div> <div ng-click="add()">增加</div> <div 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; }; })
