这是我的系列教程「Python+Dash快速web应用开发」的第四期，在上一期的文章中，我们进入了Dash核心内容——callback，get到如何在不编写js代码的情况下，轻松实现前后端异步通信，为创造任意交互方式的Dash应用打下基础。
In Dash, any "output" can have multiple "input" components. Here's a simple example that binds five inputs (thevalueproperty of twodcc.Dropdowncomponents, twodcc.RadioItemscomponents, and onedcc.Slidercomponent) to one output component (thefigureproperty of thedcc.Graphcomponent). Notice howap...
Callback functions can include multiple inputs and outputs, as well as chained callback functions. plotly, Basic Callbacks dashalso allows for interactive visualizations that change based on how the user is interacting with the visualization.

至此,我们就get到dash中回调函数的基本写法——即在@app.callback()中按照Output、Input、State的顺序依次编排角色,且回调函数输入参数(参数名随意)与已编排的Input、State角色顺序一致即可~ 3.7 更复杂的应用示例# 掌握了上文所述的dash应用最基础概念后,下面我们就可以尝试编写更复杂的交互应用场景,譬如下面的简单...
