淘汰賽：遺漏的類型錯誤：對象databaseViewModel.openList（這個）有沒有一種方法 '應用'

Question

我有這樣的代碼

var databaseViewModel = new function() { 
    var self = this; 
    self.databaseList = ko.observable(""); 
    self.id = ko.observable(""); 
    self.databaseSelected = ko.observable(""); 
    self.description = ko.observable("description"); 

    self.openList = function() { 
     alert("openList"); 
    }; 
} 

HTML：

<div data-bind="foreach: databaseList"> 
       <li><a href="javascript:void(0)" data-bind="click:'databaseViewModel.openList(this)', attr: { title: DataBaseName }"> 
        <span class="pic1"></span><span data-bind="text:DataBaseName"></span></a></li> 
       <div data-bind="attr: { 'data-something': DataBaseName }"> 
        ...</div> 
      </div> 

I want to invoke openlist when I click the link DataBaseName,how to modify the code？

Answer 1

你會想這樣做data-bind="click: $parent.openList"
