本文向大家介绍Angularjs 制作购物车功能实例代码，包括了Angularjs 制作购物车功能实例代码的使用技巧和注意事项，需要的朋友参考一下

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}}" 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：
