Say I've got a form that looks something like this:

<form action="http://example.com" method="POST">  
  <input type="text" value="text">  
  <input type="submit">  
</form>  

What would be the best method of capturing the response code (I'm not concerned with the content in this case, just making sure that the request succeeded), ideally with javascript?

You would have to add an event listener to the form (submit), cancel the event in the callback function (event.preventDefault() ), and then make the post call. Depending on the browsers you want to support, you can use fetch or xhr. Then you could do something with the data you get back.

Response.status, Syntax. var myStatus = response .status;. Value. A number (to be precise, an unsigned short). If you really wanted to get the response in Javascript (without the page refreshing), then you'll need to use AJAX, and when you start talking about using AJAX, you'll need to use a library. jQuery is by far the most popular, and my personal favourite. There's a great plugin for jQuery called Form which will do exactly what it sounds like you want.

The easiest answer: jQuery. Do something like this:

$(document).ready(function(){
   var $form = $('form');
   $form.submit(function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });
});

Using Fetch, The Fetch API provides a JavaScript interface for accessing and The Promise returned from fetch() won't reject on HTTP error status even if the response is an HTTP const response = await fetch(url, { method: 'POST', // *GET, POST, a value of application/x-www-form-urlencoded , multipart/form-data  var myStatus = response.status; Value. A number (to be precise, an unsigned short). Example. In our Fetch Response example (see Fetch Response live) we create a new Request object using the Request() constructor, passing it a JPG path.

I don't know if it is ideal but I would just do AJAX call instead this sync call. So I would delete action and method from form and on submit use preventDefault();. Next gather data by getElementById or querySelector or whatever. And finally use xhttp.open() and xhttp.sned() to send backend call to your URL.

Take a look more info about AJAX.

request.Response.statusCode JavaScript and Node.js code , console.log('Status: %d\n\n', res. Best JavaScript code snippets using request. function(err, response, body) { assert(!err); // Is our status code good? url + "/​renaissance.json"; request.get(jsonFileUrl, function (error, response, body) { if (!​error request.post({ url: url, form: params, json:true }, function(error, response,  In addition to using JavaScript to validate HTTP headers received by your API Science monitors, JavaScript can be applied for fine-grained validation of the HTTP Status Code for each API response. The status code normally associated with a successful response is 200 (“OK”). However, all 2xx status codes indicate that from the server’s point of view a valid request was received, it was processed, and an appropriate response was delivered to the client.

Fetch, At this stage we can check HTTP status, to see whether it is successful or let response = await fetch ( 'https://api.github.com/repos/javascript-tutorial/en. to submit the data in x-www-form-urlencoded encoding, rarely used. Hi! I plan to make a simple dictionary using jquery. I intend to query an existing online dictionary, get the response and display it. I have the following

AJAX XMLHttpRequest Server Response, the readyState changes. When readyState is 4 and status is 200, the response is ready: data as a string. responseXML, get the response data as XML data  AJAX - Server Response. ❮ Previous Next ❯. The readyState property holds the status of the XMLHttpRequest. The onreadystatechange property defines a function to be executed when the readyState changes. The status property and the statusText property holds the status of the XMLHttpRequest object.

HTTP and Forms :: Eloquent JavaScript, It is also passed the text status of the response. The Promise interface also allows jQuery's Ajax methods, including $.get() , to chain multiple .done() , .fail()  So as you may have noticed Ive made a few posts recently regarding form validation and Ive appreciated all the help so far. I wanted to make sure my form validated as best as possible client side
