在Dash中输入多个可移除的值

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output, State

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.Input(id='input-values', type='text', value=''),
    html.Button('Add', id='add-button', n_clicks=0),
    html.Div(id='output-values')
])

@app.callback(
    Output('output-values', 'children'),
    [Input('add-button', 'n_clicks')],
    [State('input-values', 'value')]
)
def update_output(n_clicks, value):
    if n_clicks > 0:
        values = value.split(',')
        output = []
        for val in values:
            output.append(html.Div(val))
        return output
    else:
        return ''
