            <h2>Total:${{total()}}</h2>
            <input type="hidden" name="total_remito" value="{{total()}}">
            <button type="submit" name="button">guardar</button>
        </div>
    </div>
</div>

AngularJS

app.controller("ctrlremitos", function($scope, $http) {

$scope.posts = [];

$scope.carrito = [];

$scope.clienteasignado = [];

$scope.clientes = [];

$scope.busqueda = {}

$scope.busquedaclientes = {}

$scope.queryBy = '$'

$scope.newPost = {};

$http.get(base_url + "venta/get_productos").success(function(data, timeout) {
    $scope.posts = data;
}).error(function(err) {})

$http.get(base_url + "venta/get_clientes").success(function(data) {
    $scope.clientes = data;
}).error(function(err) {})

$scope.comprar = function(_item, index) {
    $scope.carrito.push(_item)
}

$scope.asignarcliente = function(_item) {
    $scope.clienteasignado.push(_item)
}

$scope.remove = function(index) {
        $scope.carrito.splice(index, 1);
    },

    $scope.total = function() {
        var total = 0;
        angular.forEach($scope.carrito, function(p) {
            total += p.stock * p.precio;
        })
        return total;
    }

});

问题在于，当我选择产品时，推送但价值始终是股票的价值，我想要的是，当你这样做时，你总是将股票价值改为1.另外我注意到了就是当改变字段“stock”中的值时，在搜索产品的数组中也发生了变化，我不知道该怎么做:(我一直试图使这项工作正常工作很多天，我希望他们会点亮道路。

Answer 1

＆＃34; $ scope.total＆＃34;是一个函数，而不是范围变量。因此，除非您进行显式调用，否则双向绑定在此方案中不起作用。为了使它工作：对控制器和HTML执行以下更改。控制器更改：

$scope.total = 0;

$scope.comprar = function(_item, index) {
    $scope.carrito.push(_item);
    $scope.calculateTotal(); //Make an explicit call to calculation method
}

$scope.calculateTotal = function()
{
     angular.forEach($scope.carrito, function(p) {
            $scope.total += p.stock * p.precio;
        })
};

HTML更改：

<h2>Total:${{total}}</h2>
            <input type="hidden" name="total_remito" value="{{total}}">

希望这有帮助

Answer 2

我可以看到你的Html页面中没有英文，但无论如何，如果我理解你的错误，那么你正试图推送一些实际上不在你的DOM

的内容

$scope.asignarcliente = function(_item) {
$scope.clienteasignado.push(_item)
}

什么是$scope.clienteasignado ??? ;您正在显示的实际列表名为$scope.posts，如果产品出错，产品会更正我，如果这是要推送的产品列表，您需要以这种方式改正

$scope.asignarcliente = function() {
$scope.posts.push(emp);
}

ps这个函数也没有在DOM刚刚定义按钮

中调用

<button type="submit" ng-click="asignarcliente()" class="btn btn-default" data-dismiss="modal">Cerrar</button>

我希望我操纵了正确的项目，我希望它适合你

我明白了。我的问题是两个绑定。请注意，如果在给定变量中使用此表达式“::”，则只执行a-bind，然后在“stock”字段中使用值为1的ng-init。
