ADF Faces and Client Side Value with innerHTML

In ADF Faces you can leverage the full power of JavaScript. I will explain how you could assign a value from ADF Faces component to the plain HTML div.

The sample app is available on GitHub repo. It doesn't require DB connection, you can run it straight away in Oracle JDeveloper.

Look into JSF page. I have implemented ADF Faces input component with value change listener. Below this component, there is HTML div with ID ot1. We will assign a text value to this div programmatically from JS function passClientSideValue:


JavaScript function reads the value by client ID from ADF Faces component and assigns it to the innerHTML property of HTML div:


When ADF Faces value is changed, value change listener is invoked through ADF auto-submit event. In value change listener, we extract client ID of the input component and pass it to JS function through JavaScript call from Java:


This is how the end result looks like:


In particular, this approach can be useful, when you want to bypass ADF Faces validation lifecycle and display updated value despite current validation errors in the form.
