GetFocus() returns the handle of the currently focused control, so you need to compare that return value to the handle of the control you want to react upon.

js code:

---

// Get the handle of the focused control
var hFocused = Interop.Call('user32', 'GetFocus');
// Check if it's our edit control
if( hFocused === PlusWnd.GetControlHandle('MyEditControl') ) {
    // Do stuff
}

---

Or the short version:

js code:

---

// Check whether our edit control has focus
if( Interop.Call('user32', 'GetFocus') === PlusWnd.GetControlHandle('MyEditControl') ) {
    // Do stuff
}
