我正在尝试将锚点属性绑定到 KnockoutJS ViewModel 字段。我试过这样的事情：

but this doesn't work. Where I can get a list of possible data-bind values for html elements?
但这不起作用。在哪里可以获得 html 元素可能的数据绑定值列表？

Here you can find a list of all possible bindings.
在这里您可以找到所有可能绑定的列表。

on the left side (sidebar) you find links to other bindings like text, attr style and more.
在左侧（侧边栏），您可以找到指向其他绑定（如文本、属性样式等）的链接。

As an alternativeto @RichardFriend's answer(and more commonly used option), you could write a custom binding handler to make your views a wee bit more terse:
作为替代方案，以@ RichardFriend的回答（更常用的选项），你可以写一个自定义绑定处理程序，让您的观点一丁点更简洁：
ko.bindingHandlers['href'] = {
update: function(element, valueAccessor) {
element.href = ko.utils.unwrapObservable(valueAccessor());
}
};
ko.applyBindings({
myUrl: 'http://stackoverflow.com',
myText: 'Stack Overflow website'
});<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
<a data-bind="href: myUrl, text: myText"></a>回答by MarlinG
This works perfect for me
这对我来说很完美
<td class="CommandArea" rowspan="2">
<p><a href='#' data-bind="click: abandon" >Abandon</a></p>
</td>
