knockout.js - 淘汰赛：未捕获的类型错误：对象 databaseViewModel.openList(this) 没有“应用”方法

Question

我有这样的代码

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：</p>

<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>

我想点击链接DataBaseName时调用openlist，如何修改代码？</p>

Answer 1

你想做data-bind="click: $parent.openList"
