Element has class
Function: Element has class
This function helps you determine if a specific visual component (UI element) on your application screen currently has a particular style or behavior applied to it, represented by a "class." It's like asking, "Does this button currently look 'active'?" or "Is this text field marked as 'error'?"
Input
- Element: The specific visual component (like a button, text box, or image) on your application screen that you want to inspect.
- Class: The name of the style or behavior (class) you are looking for on the selected element. This is typically a single word or a hyphenated phrase, like "active", "hidden", or "is-selected".
Output
- Result: A variable that will store a "True" or "False" value.
- True: If the selected element does have the specified class.
- False: If the selected element does not have the specified class.
