So here's my issue, I am using AJAX (jQuery) to post a form to process.php but the page actually needs to echo out a response such as apple or plum. AJAX stands for Asynchronous JavaScript and XML. Yes @northkildonan, you are right, in fact, the @sgb answer is the right answer, but if you look at the jquery code, when you pass dataType it really converts the response in the specific type, but Flaashing done that already, and it didn't converted. This is the first method called in our fetch() chain, if it resolves, we then call our json() method which again returns a Promise from the response.json() call. In regular functions the this keyword represented the object that called the function, which could be the window, the document, a button or whatever..

It then performs an AJAX request to process.php with a payload of form data. Effectively, the response you get from making such a request (with no-cors specified as a mode) will contain no information about whether the request succeeded or failed, making the status code 0.

The return type varies based on the observe and responseType values that you pass to the call. AJAX stands for Asynchronous JavaScript and XML. The asynchronous method sends an HTTP request, and returns an Observable that emits the requested data when the response is received. It is also passed the text status of the response. The reasoning is to conserve memory, as buffering text of large bodies such as multipart files or images is extremely inefficient. Most implementations will specify a Removing mode from your Either text, json or jsonp, which will cause the autocomplete to use jsonp.
