Input text focus

[Mr_Li]

I am a novice in node-red, a barcode input binding project. I want to clear the barcode data by clicking the button and set the focus for the text field to reduce the click time. What should I do? I have been trying for several hours and still haven't succeeded. Please help me, thank you!
