我有一个可观察的数组:

var myObservableArray = ko.observableArray([
    { name: "Car", price: "9999" },
    { name: "Shoes", price: "20" },
    { name: "Paper", price: "1" }
]);

我正在尝试访问数组中第一项的价格.

<div data-bind="text: myObservableArray()[0]"></div>

显示:

[object Object]

我试过了:

<div data-bind="text: myObservableArray()[0].price"></div>

但这只是返回null.

这样做的正确语法是什么？

编辑:修复了下面指出的复制和粘贴错误.

我有一个使用basicHttpBinding工作的WCF服务,我正在尝试将其配置为通过https并使用SQL成员资格提供程序进行身份验证,并且为此我尝试将其转换为使用wsHttpBinding.

但是,使用更新的配置,当我尝试连接客户端时出现以下错误:

无法在ServiceModel客户端配置部分中找到引用合同"KFileService.IKFileWcfService"的默认端点元素.这可能是因为没有为您的应用程序找到配置文件,或者因为在客户端元素中找不到与此合同匹配的端点元素.

这是服务器的web.config的相关部分:
