Question

我先与Knockout一道采取初步步骤。 j 采用(两个复杂)表格计算未付账单的账面,同时铭记部分付款、费用和合同处罚。

这一计算将在PHP中处理,因为在PHP中,当时在联合材料中,I m比较少。 Knockout正在处理增加新形式领域的动态,使甚至在最复杂的情况下使用的形式具有灵活性。

为了能够正确提取数据,我将通过邮局向PHP提供三个多维阵列:

invoice[$i][name] / invoice[$i][amount] / invoice[$i][date] / ...
payment[$j][name] / ...
cost[$k][name] / ...

在联合材料中,我似乎无法解决的问题是,新的形式要素应当由Knockout.js产生,独一无二的数字应当与(一卷)相配。

data-bind="attr:{name: someFunctionToGiveUniqueName}"

I ve looked into the uniqueName-binding, but I need to have three uniqueNames and I should be able to customize the resulting name to keep the data structured.

This is my viewModel (and it works, except for the not-so-unique-naming-of-inputfields):

        <script type="text/javascript">

        // Overall viewmodel
        function ViewModel() {
            var self = this;

            // Data
            self.Hoofdsom   = ko.observableArray();
            self.Betaling   = ko.observableArray();
            self.Kost       = ko.observableArray();

            self.hsBeschr   = ko.observable();
            self.hsBedrag   = ko.observable();
            self.hsVerval   = ko.observable();

            self.hsIntr     = ko.observable();
            self.hsIntrType = ko.observable();

            self.hsSchadeType = ko.observable();
            self.hsSchadePerc = ko.observable(10);
            self.hsSchadeMin = ko.observable(0);
            self.hsSchadeMax = ko.observable(1500);

            // Initial State
            self.Hoofdsom.push("new");

            // Operations
            self.addHoofdsom = function() {
                self.Hoofdsom.push(self.Hoofdsom().length);
            }
            self.remHoofdsom = function(hfd){
                self.Hoofdsom.remove(hfd);
            }
            self.addBetaling = function() {
                self.Betaling.push(self.Betaling().length);
            }
            self.remBetaling = function(bet){
                self.Betaling.remove(bet);
            }
            self.addKost = function() {
                self.Kost.push(self.Kost().length);
            }
            self.remKost = function(kos){
                self.Kost.remove(kos);
            }
        }

        // Apply bindings
        ko.applyBindings(new ViewModel());

    </script>

我不知道我是否理解您是正确的,但认为,如果界定了,并使你自己具有类似约束力,那么 t就太困难,见

其他独一无二的价值是时间范围——请上我为您做了发言——uniqName。
