Interval

문제

2초, 4초마다 1씩 숫자를 증가시키도록 해 보자.

코드

from dash import Dash, html, dcc, Input, Output

app = Dash(__name__)

app.layout = html.Div([
    html.H1('Interval Test'),

    html.Div(id='two-count'),
    html.Div(id='four-count'),
    dcc.Interval(id='two-interval', interval=1000 * 2, n_intervals=0),
    dcc.Interval(id='four-interval', interval=1000 * 4, n_intervals=0)
])


@app.callback(
    Output('two-count', 'children'),
    Output('four-count', 'children'),
    Input('two-interval', 'n_intervals'),
    Input('four-interval', 'n_intervals')
)
def apply_slider(n_two, n_four):
    return html.Div(f"TWO Count: {n_two}"), html.Div(f"FOUR Count: {n_four}")


if __name__ == '__main__':
    app.run_server(debug=True)
