Clear input box after hitting enter

Using Streamlit
1

Hi everyone,
I’m a newbie, sorry if my question is rather stupid, but I searched before asking this question.
In terms of the input box, I want to write the input, and once I hit enter, it clears the input box. Currently the input remains in the box. I don’t want to use a submit button because I don’t want the user every time move the mouse to click on it. I wanted to create a shortkey that when I hit enter, runs the ‘submit button’ because I saw in the streamlit extras you can create a short key to go to a specific URL. But yet again I failed. Thank you!

You can use session state to store the value for the widget and clear it. Then, use the stored value in the rest of the script (not the “output” from the widget).

if 'something' not in st.session_state:
    st.session_state.something = ''

def submit():
    st.session_state.something = st.session_state.widget
    st.session_state.widget = ''

st.text_input('Something', key='widget', on_change=submit)

st.write(f'Last submission: {st.session_state.something}')
