JS如何将序列化对象转换为数组？

Using jquery.nestable.min.js, I get a the following output:

[{"id":32},{"id":29},{"id":30}]

This current output is coming from the following code:

const myList = JSON.stringify(list.nestable('serialize'));

I need it to simply be:

32, 29, 30

End result is that I would like to read a normal array in PHP. I'm looking to either convert myList to an array in Javascript and POST that array, or convert the current version of the object to an array inside PHP, whichever is most effective.

I've tried to use json_decode in PHP, but I get empty values. So I figured if I can just convert to a normal Array before sending it off to PHP, then it would be less of a hassle.

Thank you.

This may be duplicated, in which case, please point me to the best answer
