Python 如何将在Dash中触发回调的按钮与在同一按钮单击时触发的其他回调同步

我有一个Dash应用程序，我试图通过一个按钮触发回调来重新创建它。我只能让我的

n_单击

为第一次单击触发用户输入值。这是唯一一次在整个回调过程中同步按钮。我理解为什么，因为在我的第二次回调中，

tickers（）

（图一）中，

n\u clicks

的值将始终保持

True

有哪些方法可以让我的按钮在每次回调时同步并启动。在我的仪表板中发生的事情是，在第一次单击之后，用户在输入中输入的每个值都会触发我的回调，完全忽略我的

n_单击

我如何解决这个问题

# My input dropdown that gets fired off thanks to n_clicks input

@app.callback(
    [Output(component_id='input-warning', component_property='children'),
    Output(component_id='dynamic-dropdown',component_property='options')],
    [Input('button', 'n_clicks')],
    state=[State(component_id='dynamic-dropdown', component_property='value')]
) 
def update_output_div(n_clicks, value):
    if n_clicks:
        n_clicks += 1
        if value is None:
            return [[], OPTIONS]
        elif len(value) >= 4:
            children = html.P("limit reached...",id='input-warning')
            return [children, [o for o in OPTIONS if o["value"] in value]]  
        else:
        # Make sure that the set values are in the option list, else they will disappear
        # from the shown select list, but still part of the `value`.
            return [
                o for o in OPTIONS if value.upper() in o["label"].upper() or o["value"] in (value or [])
            ]
    else:
        conn.rollback()
        return PreventUpdate
