您好，我对使用函数和onclick动作来调用javascript很陌生，因此我可以提供一些帮助。基本上，我已经在WordPress上安装了一个插件，该插件以小部件的形式向页面添加了一个按钮，一旦单击它便启动脚本。但是，我不喜欢他们的按钮，因此我尝试编写自己的代码，但我希望它像那样启动脚本。
这是脚本代码：
/*
* Timely BookButton plugin
* Example usage:
* var button = new timelyButton('doedayspa');
*
* Booking process can be kicked off manually by calling the start method on the button instance e.g.
* button.start();
*
*/
// Need this for legacy support of older versions of the BookingButton
var timelyButton;

Windows: function () {

那么，当我单击按钮时如何运行此javascript？
任何帮助将不胜感激！

如果单击该按钮，则可以自动创建脚本标签。
document.getElementById('myButton').addEventListener('click', () => {
const script = document.createElement("script");
script.src = 'my-other-file.js';
document.head.appendChild(script);
})<button id="myButton">Load JS File</button>
