Get All Elements of Certain Type on a Website

I need to find all Input elements (sap.m.Input) on a website. I know I can find an element by its ID via sap.ui.getCore().byId() but this does not help me here.

I am looking for something like sap.ui.getCore().getByType("sap.m.Input"). How do I do this?

Edit: I do not have access to the source code of the website, I am injecting a javascript via a chrome extension on websites which use SAPUI5

Solution

From the current page

<mvc:View ...>
  <Input fieldGroupIds="myInputs" />
</mvc:View>

// In the Controller
this.getView().getControlsByFieldGroupId("myInputs").filter(c => c.isA("sap.m.Input"));

From the whole app

Leveraging this solution in Get list of all instantiated controls in registry:

const allRegisteredControls = sap.ui.getCore().byFieldGroupId(""); // From https://stackoverflow.com/a/54227512/5846045
const inputControls = allRegisteredControls.filter(c => c.isA("sap.m.Input"));

^{API reference: sap.ui.base.Object#isA}

This returns all registered instances of the given type. Please not that already destroyed elements won't be included.
