问题 I am trying to understand a button on a third party site my company uses. The button signs up a user for a class. <a class="btn btn-large btn-blue" href="javascript:void(0);" data-bind="click: $root.clickAction.bind($data, ActionType)"> <span data-bind="text: Title">Sign up</span></a> I was hoping to provide this button on a page in our company internal website, but I am not familiar with Knockout. I understand a GET request so if that button did something like this then I would get it.
