Implementation Steps:

1. Navigate to https://make.powerapps.com

2. Click More --> Select Tables

3. Open the Table where you want to change the Form Text

In my Scenario I need to Change the Text Based on Boolean Field.

4. Boolean Field

• Name : Change Text
  • Yes --> If yes then Change Text to Selected Yes
  • No --> If No then Change Text to Selected No

5. Now Create a Web Resource then Upload Below Code

function onChangeBooleanField(executionContext) {
 var formContext = executionContext.getFormContext();
 if (formContext.getAttribute("crd20_changetext").getValue()) {
 formContext.getControl('name').setLabel('Selected Yes');
 } else {
 formContext.getControl('name').setLabel('Selected No');
 }
}

// crd20_changetext --> Boolean Field Logical Name

//name --> Label to be Changed

6. I have Written function in OnChange of Boolean Field

7. Once Code Written Refresh the Account Form

As i said written Code in On Change

Now if i change Value to Yes then You will see Selected Yes as Label

Now if i change to No then You will see Selected No as Label

That's it 🙂

Using Change label in JavaScript we can change the Label Text.
