FormData.get is undefined in Chrome
https://developer.mozilla.org/en-US/docs/Web/API/FormData/get
回答1:
By default, Chrome does not support the .get() method, as well as delete, get, getAll, has, and set. Although you can enable that functionality by activating an experimental flag, note from MDN:
[2] Chrome support for methods other than append is currently behind the "Enable Experimental Web Platform Features" flag.
For activating flags in Chrome you can go to the following link:
chrome://flags/#enable-experimental-webkit-features
