            <button type="submit" name="button">guardar</button>

</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;
    }

});

问题是,当我 select 一个产品进行推送时,但价值始终是库存的价值,我想要的是,当你进行推送时,你总是将库存价值更改为1. 我注意到的另一件事是,当更改字段 "stock" 中的值时,产品搜索数组中的值也发生了更改,我不知道该怎么做 :( 我一直在努力使这项工作正确多日,希望他们能指路。

问候

https://github.com/outthesystem/facturacion-codeigniter

"$scope.total" 是一个函数,不是作用域变量。 因此,除非您进行显式调用,否则双向绑定在这种情况下不起作用。 让它工作: 在控制器和 HTML 上进行以下更改。 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 变化:

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

希望对您有所帮助

我可以看到您的 Html 页面中的内容不是英语,但无论如何,如果我理解您的错误是您正在尝试推送实际上不在您的 DOM

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

什么是$scope.clienteasignado??? ;你显示的实际列表我被命名为 $scope.posts for products 如果我错了请纠正我所以如果这是要推送的产品列表你需要这样纠正它

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

ps这个函数在DOM中也没有调用,你只是定义了一个按钮

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

我希望我操作的是正确的项目,我希望它对你有用

我明白了。我的问题是双重绑定。请注意,如果您在给定变量中使用此表达式“::”,它只会执行绑定,然后在 "stock" 字段中使用值为 1 的 ng-init。
