javascript - How can you bind with Knockout without using the html attribute tag data-bind value?

Question

Normally with KnockoutJs you would have something like this:

    <input type="text" name="Capital" id="Capital" data-bind="value: capital">

During the binding, we would create an observable:

   this.capital = ko.observable(100);

But let's say that we cannot add the data-bind attribute. Also not after page is loaded..and after that.. never.

How would we be able to bind to our viewmodel using Knockout ?

Answer 1

如果您不想将data-bind标记添加到元素，则需要编写自己的自定义 bindingProvider 以允许您在 javscript 中编写绑定，或者您可以使用Knockout.Unobtrusive插件，它为您提供此功能。
