问题描述

这个语法很剃刀，我正在转换为基因敲除JS ..任何帮助，感激不尽..

This sytax is in razor that I am converting to knockoutJS.. any help much appreciated..

Where ItemStatus.Active is 0 in an enum in c# ( backend )

@foreach (var employee in Employees.Where(x => x.Status == ItemStatus.Active))
{   
  <div class="someclass">
  <span class="label">Name:</span>
  <span class="value">@employee.Name</span> 
  </div>
}

我如何在淘汰赛foreach中复制这种逻辑，即我只想显示当前在职或受雇的员工

How do I replicate this logic in knockout foreach, ie I only want to show employees who are currently active or employed

谢谢

推荐答案

任何JavaScript表达式都可以在淘汰赛绑定中使用.

Any JavaScript expression can be used in Knockout bindings.

因此，您可以使用过滤器功能(ES6):

So you could use the filter function (ES6):

<!-- ko foreach: Employees.filter(employee => employee.Status == 0) -->
...
<!-- /ko -->

或其他任何过滤方法:

<!-- ko foreach: ko.utils.arrayFilter(Employees.filter, function(employee) { return employee.Status == 0; }) -->
...
<!-- /ko -->
