Have you ever needed to do jQuery Ajax PUT request? It’s not as hard as you think.
Recently I’ve written a simple API as part of a school project, and the front-end team supposed to access the back-end data by standard HTTP requests like GET, POST, PUT, DELETE.
My front-end team mate encountered some troubles doing jQuery Cross-Origin ajax request for POST and PUT requests that have Form Data parameters.
var myData = new FormData();
There are a few parts that are not so obvious,
contentType: "multipart/form-data" and processData: false are needed to allow FormData to be transmitted as is.
Now you can get back to your code and start trying.
