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=this angular.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=this angular.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.$apply(); }) } }) //单选 A.directive('oneCheck',function(){ return function(scope, element, attr){ element.click(function(){ var This=this angular.forEach(scope.dataList,function(data,index,array){ if(attr.items==data.items){ var isCheck=$(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}}"> <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> <>
效果如图所示：
