淘汰赛推动不更新GUI



当我将项目添加到observablearray时,我正在努力敲除,并进行UI更新。Intial Listing和DeleteMployee工作正常并更新UI Arpropriatley,但是当我尝试添加员工时,UI根本没有更新。以下是ViewModel和HTML。感谢我能为此获得的任何帮助。

ViewModel:

function viewModel() {
        var self = this;
        self.employees = ko.observableArray();
        self.deleteEmployee = function () {
            var employee = this;
            dataservice.del(this.id, function () {
                self.employees.remove(employee);
            })
        },
        self.addEmployee = function () {
            var emp = {};
            emp.Name = $("#newName").val();
            emp.Email = $("#newEmail").val();
            dataservice.add(emp, function (data) {
                var employee = new Employee(data.id, emp.Name, emp.Email);
                self.employees.push(employee);
            });
        }.bind(self);
        $.each(data.rows, function (index, row) {
            self.employees.push(new Employee(row.value.Id, row.value.Name, row.value.Email));
        });
        return {
            employees: self.employees,
            deleteEmployee: self.deleteEmployee,
            addEmployee: self.addEmployee
        }
    };
    ko.applyBindings(new viewModel());



html

<article data-bind="foreach: employees">
                <div class="emp">
                    <div class="empTop">

                        <div class="del" data-bind="click: $parent.deleteEmployee, clickBubble: false"></div>
                    </div>
                    <div class="empContent">

                    </div>
                </div>                 
            </article>
            <aside>
                <h3>Create</h3>
                <div>
                    <div class="row">
                        <label for="newName">Name</label>
                        <input id="newName" name="newName" type="text">
                    </div>
                    <div class="row">
                        <label for="newEmail">Email</label>
                        <input id="newEmail" name="newEmail" type="text">
                    </div>
                    <div class="row">
                        <input type="button" value="Create" data-bind="click: addEmployee">
                    </div>
                </div>
            </aside>

看来,问题不在敲除。我将您的代码放入JSFIDDLE中,在JavaScript中评论了几行,但没有触摸您的HTML,创建工作正常。

看小提琴:http://jsfiddle.net/mshmelev/zf5pc/

所以,问题可能是:

  1. dataservice.add()功能未调用您的回调
  2. 您的Employee类有问题(我在小提琴中创建了一个存根)

结果发现渲染的项目,但是,这令人尴尬,我有一些jQuery隐藏了beeing beeing添加了$('。emp')。hide()。这个小错误使我造成了塞弗拉小时的困惑。谢谢您的所有建议。
