推荐答案
您仍然需要写出绑定的名称处理程序点击：
You still need to write out the name of the binding handler click:
<button type="button" data-sbind="click: btnClick">button</button>
你不需要这整个绑定对象与 sbtnClick ，只需写：
And you don't need this whole bindings object with the sbtnClick, just write:
var viewModel = function () {
this.btnClick = function () {
alert('clicked');
};
};
ko.bindingProvider.instance = new ko.secureBindingsProvider();
ko.applyBindings(new viewModel());
演示 JSFiddle 。
