Angularjs 制作购物车功能实例代码

时间：2021-05-28

初学angularJS 闲暇之余做了个小案例。

功能：计算购物车商品的价格，以及删除购物车商品。

以下是完整案例（jQuery和angularjs需要自己引入）

<!doctype html><html ng-app="myApp"><head><meta charset="utf-8"><title>无标题文档</title><style>.cursors{cursor:pointer}</style><script src="js/jquery-1.11.1.js"></script><script src="js/angular.min.js"></script><script>var A=angular.module('myApp',[]);//购物车 加A.directive('myAdds',function(){return {link:function(scope, element, attr){element.click(function(){var This=thisangular.forEach(scope.dataList,function(data,index,array){if(attr.items==data.items){data.num=parseInt(data.num)+1;scope.allPrices();scope.$apply() //刷新视图}});});} }})//购物车 减A.directive('myMinus',function(){return {link:function(scope, element, attr){element.click(function(){var This=thisangular.forEach(scope.dataList,function(data,index,array){if(attr.items==data.items){if(data.num<=1){if(confirm('是否删除该产品')){data.num=0;$(This).siblings('input').val(0);scope.allPrices();scope.$apply();//delete array[index];scope.dataList.splice(index,1)$(This).parents('tr').remove();}}else{data.num=parseInt(data.num)-1;};scope.allPrices();scope.$apply();}});});} }})//全选，全不选A.directive('allOrcan',function(){return function(scope, element, attr){element.click(function(){var isCheck=$(this).find('input').prop('checked');if(isCheck){$('input[type=checkbox]').prop('checked',true);}else{$('input[type=checkbox]').not($('input[type=checkbox]').eq(0)).prop('checked',false);}angular.forEach(scope.dataList,function(data,index,array){data.Bol=isCheck;})scope.allPrices();scope.$apply();})}})//单选A.directive('oneCheck',function(){return function(scope, element, attr){element.click(function(){var This=thisangular.forEach(scope.dataList,function(data,index,array){if(attr.items==data.items){var isCheck=$(This).prop('checked');data.Bol=isCheck;scope.allPrices();scope.$apply();}})});}})A.controller('myAngular',['$scope','$filter',function($scope,$filter){$scope.dataList=[//初始化购物车的数据{Bol:'false',name:'洗衣机',num:'1',items:'0',oneprice:'900',price:''},{Bol:'false',name:'热水器',num:'1',items:'1',oneprice:'110',price:''},{Bol:'false',name:'空调',num:'1',items:'2',oneprice:'116',price:''},{Bol:'false',name:'冰箱',num:'1',items:'3',oneprice:'2087',price:''},{Bol:'false',name:'电磁炉',num:'1',items:'4',oneprice:'135',price:''},{Bol:'false',name:'被子',num:'1',items:'5',oneprice:'50',price:''},{Bol:'false',name:'本子',num:'1',items:'6',oneprice:'2',price:''},{Bol:'false',name:'笔',num:'1',items:'7',oneprice:'115',price:''},{Bol:'false',name:'杯子',num:'1',items:'8',oneprice:'12',price:''},{Bol:'false',name:'书',num:'1',items:'9',oneprice:'5',price:''},{Bol:'false',name:'零食',num:'1',items:'10',oneprice:'13',price:''}];//总价格的计算$scope.allPrices=function(){$scope.allprice=0;angular.forEach($scope.dataList,function(data,index,array){data.price=data.num*data.oneprice;if(data.Bol==true){$scope.allprice+=parseInt(data.price);}})return $scope.allprice;};//按单价排序$scope.CartSort=function(arg){angular.forEach($scope.dataList,function(data,index,array){arguments.callee['CartSort('+arg+')']=!arguments.callee['CartSort('+arg+')']$scope.dataList=$filter('orderBy')($scope.dataList,arg,arguments.callee['CartSort('+arg+')'])})}}])</script></head><body ng-controller="myAngular"><table border="1"> <tr> <td><label all-orcan><input type="checkbox">全选/取消全选 </label></td> <td>名称</td> <td>数量</td> <td ng-click='CartSort("oneprice")'>单价</td> <td>价格</td> </tr> <tr ng-repeat="data in dataList"> <td><input type="checkbox" one-check items={{data.items}}></td> <td ng-cloak>{{data.name}}</td> <td><input type="text" ng-cloak ng-model="data.num" items="{{data.items}}" style="width:50px;text-align:center;"> <button my-adds items="{{data.items}}" ng-class="{cursors:true}" >+</button> <button my-minus items="{{data.items}}" ng-class="{cursors:true}" >-</button>　</td> <td ng-cloak>{{data.oneprice}}</td> <td ng-cloak>{{data.price}}</td> </tr> </table> <div>总价格：{{allPrices()}}</div></body></html><!--<script>alert(0)</script>-->

效果如图所示：
