Question

这是我动态添加行的脚本。我想在一个结果中对每个总结果求和。如何对每个结果求和，添加行和删除行。

//start
   $scope.total = function () {

    var totalt = 0;
        angular.forEach ($scope.dataInvoce.Invoicetoitem.items, function (item) {
        totalt += item.quantity * item.price * (1 - item.discount / 100);
        });
        return totalt;
    };
//finish//This is script perfect work, but i have problem in my console/TypeError: Cannot read property 'Invoicetoitem' of undefined/

HTML：

 <div class="container">
                    <div class="row">
                    <form>

                    </div>
                </div>

这是我70％的脚本，另一个信息不是dangerouse

看起来错误是由未定义的scope.dataInvoce.Invoicetoitem对象引起的。尝试将数组初始化为[]。

//启动

   $scope.total = function () {
   $scope.dataInvoce = {Invoicetoitem: {items: []}}; //add this line
    var totalt = 0;
        angular.forEach ($scope.dataInvoce.Invoicetoitem.items, function (item) {
        totalt += item.quantity * item.price * (1 - item.discount / 100);
        });
        return totalt;
    };

AngularJS：总结我的结果的错误？
