问题 I'm rewriting the UI for my web-app in react.js, and I'm a bit stumped by the following problem. I have a page which displays data obtained via an AJAX request, and below that, a form to submit new data is displayed. All good. Now, I want to add a <select> element to the form, and fetch the values from a different location (url).
