Question

我想使用敲除安全绑定。这样做我使用knockout-secure-binding.js。

谁能解释为什么以下代码不起作用？它会抛出一个错误`

Uncaught＃＆lt;对象＆gt; knockout-secure-binding.js：74`

在行ko.applyBindings(new viewModel());

之后

<html>
<head>
    <title></title>
    <script src="scripts/knockout-3.0.0-min.js"></script>
    <script src="knockout-secure-binding-master/dist/knockout-secure-binding.js"></script>

</head>
<body>
    <button type="button" data-sbind="sbtnClick">button</button>

    <script>
        var bindings = {
            sbtnClick: function () {
                return {click: this.btnClick};
            }
        };

        var viewModel = function () {
            this.btnClick = function () {
                alert('clicked');
            };
        };

        ko.bindingProvider.instance = new ko.secureBindingsProvider(bindings);
        ko.applyBindings(new viewModel());
    </script>

</body>
</html>

您仍然需要写出绑定处理程序click的名称：

<button type="button" data-sbind="click: btnClick">button</button>

你不需要bindings这个整个sbtnClick对象，只需写下：

var viewModel = function () {
    this.btnClick = function () {
        alert('clicked');
    };
};

ko.bindingProvider.instance = new ko.secureBindingsProvider();
ko.applyBindings(new viewModel());

演示JSFiddle。
