DevOps, CI/CD and Automation

for example, I define a JET button like this:

<button id= "button" data-bind="click: buttonClick,
     ojComponent: { component: 'ojButton', label: 'A button element' }">
</button>

When I get the button DOM element in HTML, how can I get the JET component type of this DOM element?

In this example, I want to get "ojButton" as the result.

Is there any JET api for this?

And I come up with a way to get this, which is to analysis the value of 'data-bind' attribute coz it contains component definition.

But I don't know if this method is stable and if component definition will always display in HTML code at client side.
