为加载 API 添加事件监听器

Question

I have a script to execute for elements of an API (named ButterCMS), and I have to wait for the loading of the API to execute this code. If not, the elements of the API are not yet created and the script return an error.

The problem is that is can't find how to do that.
Here is the code for load the API:

const Butter = require('buttercms')
export const butter = Butter('your-api-token')

For this you can load the script  dynamically when your api will return response
after that script tag will be loaded.

fetch("url").then(  
var Script = document.createElement('script');
Script.setAttribute('src','your script url');
document.head.appendChild(Script);
)
