Plotly/Dash:如何防止动态插入的链接/元素在用户不点击的情况下自动触发回调？

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

app = dash.Dash(__name__)

app.layout = html.Div(
    [
        dcc.Input(id="input-1", type="text"),
        html.Button("Submit", id="submit-button"),
        html.Div(id="output"),
    ]
)

@app.callback(
    Output("output", "children"),
    [Input("submit-button", "n_clicks")],
    [State("input-1", "value")]
)
def update_output(n_clicks, input_value):
    if n_clicks is None:
        raise PreventUpdate
    else:
        return f"You have entered: {input_value}"

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