根据输入过滤基因敲除阵列

Question

我有一个基因敲除数组，用于填充表格。我也有用于数据绑定到过滤数组中的变量的输入。 。 。我需要使用这些输入来过滤我的数组，并只显示该数组....我怎么能做到这一点在我的FilteredAray下面的？是。

<td><input data-bind="value: First, valueUpdate: 'afterkeydown'" /></td> 
<td><input data-bind="value: Second, valueUpdate: 'afterkeydown'"/></td> 
<td><input data-bind="value: Third, valueUpdate: 'afterkeydown'" /></td> 
<td><input data-bind="value: Fourth, valueUpdate: 'afterkeydown'"/></td> 

淘汰赛视图模型：

self.First = ko.observable(''); 
    self.Second = ko.observable(''); 
    self.Third = ko.observable(''); 
    self.Fourth = ko.observable(''); 

    self.FilteredArray = ko.computed(function() { 

     var First = self.First(); 
     var Second = self.Second(); 
     var Third = self.Third(); 
     var Fourth = self.Fourth(); 


     ? Filter self.PeopleArray() 


    }, self); 

我试图筛选基于您正在寻找滤镜阵列输入

Answer 1

可观察到的阵列PeopleArray（）。它只返回一个新数组，只有返回true的结果形成回调。

self.array = ko.obserableArray(); 
    self.filter1 = ko.observable(); 
    self.filter2 = ko.observable(); 
    self.filter3 = ko.observable(); 
    self.filter4 = ko.observable(); 
    self.array = ko.observableArray(); 
    self.filteredArray = ko.computed(function() { 
     return ko.utils.arrayFilter(self.array(), function (item) { 
      //logic for filter1 
      //logic for filter2 
      //logic for filter3 
      //logic for filter4 
      //if result matches the filter for return true, if not test next filter 
      }); 
      }); 
    });
