I am sending a form post to a third party and it is returning a page with Success if the action is done. Once I get the success page, I need to redirect user to a Thank You page. Can somebody tell me how the see if the success page is returned and redirect to another page?
<form name="abc" method="POST" action="third party url" >
<input />
<input />
</form>
... how about submitting the form and receiving response in an iframe? If you can use an iframe you'll be able to detect the change then.
the code goes like this:
<form name="abc" method="POST" action="third party url" >
<input/>
<input/>
</form>
but i am not sure how to capture the response
You won't be able to do this easily with plain javascript. When you post a form, the form inputs are sent to the server and your page is refreshed - the data is handled on the server side. That is, the submit() function doesn't actually return anything, it just sends the form data to the server.
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.

I am trying to use an HTML form to execute a post request. I know that in general AJAX is probably a better way to go about this, but my use case is very simple and I have to upload a file in this form submission (which is really easy just using HTML forms). Anyways, everything works, but for some reason my browser is downloading the contents of my POST request response, which I do not want to happen. I want nothing to actually occur when I submit the post request other than the post request being sent out.
Here is the HTML portion of my code:
<form enctype="multipart/form-data" action="/action" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="30000"/>
<input type="text" name="email" id="email">
<input type="file" name="file" id="file" accept="image/*">
<input type="submit">
</form>
I am not sure that it is relevant, but I am using a Flask webserver and here is the response I am returning:
response = {"status": 200}
return Response(json.dumps(response), mimetype='applications/json')
The issue is that I keep having files downloaded from my browser with '{"status": 200}' in them.
Status : 200 indicates.
The request has succeeded.
So an OK status response is sent to the location, /action as you have mentioned in action="/action". So I'm guessing this is the view you wanted to send the POST request too.
I don't have the code for your /action view, but either :
This is not the view you intended to send it too.
It is the view you intended to send it too.
So if its not the correct view, what you can do is, use jinja templating and mention your view like this.
<form method="POST" action="{{url_for('xyz')}}">
Notice how I use the url_for() in jinja templating to specify route.
And if its the correct view, i can answer the question by seeing your code for the view called action.
Most likely what could be wrong though is,
your return function is erroneous. Check the return function again.
I want to send an email which has a submit button, on click of which, a post request would be triggered.
How can I create such an email?
What kind of code would be required?
The code I have written:
<h1>Show a push button:</h1>
<p>The button below activates a JavaScript when it is clicked.</p>
<br/>
<input type="button" value="Click me" onclick="msg()">
That approach you appear to be trying to take is to use JavaScript. This absolutely will not work. Email clients do not allow JavaScript to execute in HTML formatted email.
You could place a regular form inside the email:
<form action="http://example.com" method="POST">
<button>Submit</button>
</form>
… however, form support in email clients is not perfect.
The safe approach is to ask the user to do a two-step process: use a regular link to a webpage containing the form which the user can load in their web browser and then click the submit button for.
If you don't care about the usual protections, then you could have JavaScript submit the form on that page automatically, or change the endpoint that expects a POST request to expect a GET request and use a regular link in the original email.
Is it possible to fire off an http DELETE using an html form? I have an app that requires an http delete but when I try posting to it with my form, it tells me the method is not allowed and to try DELETE. Here is my form code:
<form method='delete' action='/groups/dissolve/$org_ID' />
<input class='btn btn-danger' type='submit' value='close group forever' style='font-size:82.5%' />
</form>
I am following instructions I found on this site: http://amundsen.com/examples/put-delete-forms/
When I use the REST client plugin for FireFox and send an http delete, it works. Does not work from the form I wrote above. Help?
Thanks
Nope - you cannot code HTTP verbs like "DELETE" from an HTML 4.x or XHTML form:

A proposal for supporting PUT and DELETE in HTML Forms
(I assume that even thought it isn't possible in straight HTML that you still want to get it done.)
You can do it with a bit of Jquery:
How to send a PUT/DELETE request in jQuery?
Override the submit button's behavior and call your own code to process the delete.
I am trying to make a form in html that uses the value you enter to form the destination URL.
<form action="../search/${params.q}" method="post" id="q">
Busqueda: <input type="text" name="q" /><br />
</form>
This is what i am doing, but it does not work, any cluess? thanks!
You'd need to handle this using a script - either server-side or on the client (JavaScript).
HTML alone can't handle parameters in the way you're using them.
So you'd need to either POST the form (as you're already doing) and handle the postback by redirecting your request to the new address, or use JavaScript to capture the field's value when a submit button is clicked and loading the new address in the browser window.
I'd suggest server-side is the best option as JavaScript might be disabled or unavailable.
I am not a big web programmer, and have a friend who wants me to help him with something.
He wants to be able to have a form that once it is submitted changes to say something like "Thanks for submitting" and have the form info disappear. He wants it to be easy for anyone to use, so he can give it to various people to use on their sites.
I was thinking I could use javascript to do it, but not really 100% sure. I want to avoid anything that isn't HTML as much as possible so that it will be usable by as many people as possible.
Thanks.
What is supposed to happen to the information in the form? Doesn't matter?
If you want it to be pure HTML there's only one good solution: Write one HTML page with the form, and another almost identical one with the success message in place and the form data hidden. Simple.
On the submitting side:
<h1>Email Subscription:</h1>
<form action="successForm.html">
<input type="text" name="emailAddress" />
<button type="submit">Send Info</button>
</form>
On the receiving side (successForm.html)
<h1>Email Subscription:</h1>
<p>Great job, you submitted!</p>
However, if you need something to change on the very same page, you're going to have to use something non-HTML. HTML just won't make any decisions about what to display. It is dumb... it just displays.
It's very easy to use JavaScript to detect when the form was submitted, and then hide the elements you need to hide, and show the success message:
<!-- Goes in the <head> or in a seperate script -->
<script type="text/javascript">
var theSubmitButton = document.getElementById('formSubmit');
theSubmitButton.onclick = function() {
var theFormItself =
document.getElementById('theForm');
theFormItself.style.display = 'none';
var theSuccessMessage =
document.getElementById('successMessage');
theSuccessMessage.style.display = 'block';
}
</script>
<!-- Goes in the body -->
<h1>Email Subscription:</h1>
<p id="successMessage">You submitted the form, good job!</p>
<form id="theForm" action="successForm.html">
<input type="text" name="emailAddress" />
<button id="formSubmit" type="submit">Send Info</button>
</form>
Of course, this example is oversimplified. It doesn't do anything with the data, and it doesn't follow best practices, or check that the data is valid in any way. I'm just trying to give a basic idea of how to use JavaScript for this purpose. If you're not a programmer, then coming up with a small, distributable piece of software might be a good job for someone else.
However, you still need some mechanism to store, email or otherwise DO something with the form. Add an edit to your question and I'll be happy to clarify my answer with a specific example.
(Another note, I didn't try to run that Javascript, so if you see an error, please just note and I'll fix it)
Try the jquery form plugin. This will achieve what you're after in an elegant way with minimal coding. In addition to this you'll need to download jquery.
This is a javascript solution, however it's safe to assume that everyone is using a javascript capable browser.
The standard way to do this is to submit the form to a different page (submit.php, for example), which provides a new page with the thankyou message. No javascript, no DHTML.
You could use javascript to replace the innerHTML of a huge div containing everything, or remove all the elements, but I'd advise against it.
There's 2 options:
Old school forms:
Person clicks submit and form data gets sent server side via GET or POST,
the page loads again and displays "Thanks for submitting"
New school javascript AJAX
Person clicks submit and javascript submits form data to server side via AJAX and removes the form elements to then add "Thanks for submitting"
Anything else is some hybrid of both these techniques.
I know you want to avoid anything other than html but this simple php code may help. You could use php within the page
fill out form and press submit to send data to form handler
In form handler, have data processed and then redirect back to the form page with a header('Location: yourwebaddresshere?form=submited');
Then in the original form page, add a php IF statement above the form code:
$url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
if(strpos($url, 'form=submited')) {
echo 'Your thank you message here';
exit(); // Use this to stop code after this statement from loading
}
