If the form is refreshing the page, you'll need to use preventDefault to cancel its default behaviour then use reset() to reset the form.
const form = document.querySelector('form');
form.addEventListener('submit', e => {
e.preventDefault();
[...form.elements].forEach(input => console.log(`${input.name}: ${input.value}`)); // Not Important
form.reset();
});
<form method="POST">
<input type="text" name="name" placeholder="name">
<input type="password" name="password" placeholder="password">
<button type="submit">Submit</button>
</form>

In JavaScript there is a function for forms which will reset the form clearing all the data in it, ready for another submit. This can be accomplished by running a JavaScript function on submit. This requires a couple changes in your code.
Firstly, we need to change this:
<button type="submit" class="btn btn-success w-100 submit">Send Message</button>
to this:
<button type="button" onclick="submitForm1()" class="btn btn-success w-100 submit">Send Message</button>
Once done, we can add some JavaScript to your page. If you have a JavaScript file linked to the page already, you can just add this code to that.
function submitForm1() {
let form = document.getElementsByClassName("gform");
form.submit();
form.reset();
}
You can also use document.getElementById("[id]"); and add an ID to your form. This is also preferable.

The first thing that comes to mind it's do all this on js so you can through ajax request send what you want. But I think it's not what you're looking for. You can't send data from page without refreshing, that's how it's work, php or html with some functional. You can change ...
<button type="button" class="btn btn-success w-100">Send Message</button>
... and collect all data by JavaScript and send it through ajax.

How to start automatic download of pdf on after form submission

I am new into PHP and Html , I have a form where I am able to post details using third party service.I want to make this form submission in such a way that after submission this should start pdf download automatically.It should perform 2 actions on same button click. I have gone through many solutions but I am not able to make this work. Here is my form
<div class="modal-body">
<div class="media-container-column" data-form-type="formoid">
<div data-form-alert="" hidden="" class="align-center" > Thanks for filling out the form use this link to Download </div>
<form class="mbr-form" action="https://mobirise.com/ " method="post" data-form-title="Mobirise Form"><input type="hidden" name="email" data-form-email="true" value="bUMCs/mtytHWYRo/XjN7tA1PqfT+NB00KjPTWZfuYXvKQmJxQUOr1gzeKJUJwLqxqXI/Euh3h4TzMmnq0FW5UjTC1AjsnumlJFTc7U5521K+f6PwqF4lRJdVha0cCPLW" data-form-field="Email">
<div data-for="name">
<div class="form-group">
<input type="text" class="form-control px-3" name="name" data-form-field="Name" placeholder="Name" required="" id="name-header15-c">
</div>
</div>
<div data-for="email">
<div class="form-group">
<input type="email" class="form-control px-3" name="email" data-form-field="Email" placeholder="Email" required="" id="email-header15-c">
</div>
</div>
<div data-for="phone">
<div class="form-group">
<input type="tel" class="form-control px-3" name="phone" data-form-field="Phone" placeholder="Phone" id="phone-header15-c">
</div>
</div>
<span class="input-group-btn"><button onClick="header.php" type="submit" class="btn btn-secondary btn-form display-4">Download</button></span>
</form>
</div>
</div>
This form submission is working fine, how can I start downloading pdf after this, any sample code in javascript or php would be helpful.Thanks

You need to add an id="SampleForm" in your form.
<div class="modal-body">
<div class="media-container-column" data-form-type="formoid">
<div data-form-alert="" hidden="" class="align-center" > Thanks for filling out the form use this link to Download </div>
<form id="SampleForm" class="mbr-form" action="https://mobirise.com/ " method="post" data-form-title="Mobirise Form"><input type="hidden" name="email" data-form-email="true" value="bUMCs/mtytHWYRo/XjN7tA1PqfT+NB00KjPTWZfuYXvKQmJxQUOr1gzeKJUJwLqxqXI/Euh3h4TzMmnq0FW5UjTC1AjsnumlJFTc7U5521K+f6PwqF4lRJdVha0cCPLW" data-form-field="Email">
<div data-for="name">
<div class="form-group">
<input type="text" class="form-control px-3" name="name" data-form-field="Name" placeholder="Name" required="" id="name-header15-c">
</div>
</div>
<div data-for="email">
<div class="form-group">
<input type="email" class="form-control px-3" name="email" data-form-field="Email" placeholder="Email" required="" id="email-header15-c">
</div>
</div>
<div data-for="phone">
<div class="form-group">
<input type="tel" class="form-control px-3" name="phone" data-form-field="Phone" placeholder="Phone" id="phone-header15-c">
</div>
</div>
<span class="input-group-btn"><button onClick="header.php" type="submit" class="btn btn-secondary btn-form display-4">Download</button></span>
</form>
</div>
</div>
Then you need to add some code to process download on form Submit event.
<script>
var pdfUrl = "https://example.com/link-to-your-pdf";
$('#SampleForm').on('submit', function () {
window.open(pdfUrl, '_blank');
});
</script>

You'll have to handle submission with Javascript, instead of the default one.
There is some documentation about sending form submission throught javascript:
https://developer.mozilla.org/en-US/docs/Learn/Forms/Sending_forms_through_JavaScript

to redirect the same page after form submit

I have a form in my webpage Index.html. When I submit my form it redirects to the action page.
I want the page to redirect to itself (index.html) after completing the action.
<div class="container">
<div class="row marginbot-80">
<div class="col-md-8 col-md-offset-2">
<form id="contact-form" method="post" action="mailfunc.php" class="wow bounceInUp" data-wow-offset="10" data-wow-delay="0.2s">
<div class="row marginbot-20">
<div class="col-md-6 xs-marginbot-20">
<input type="text" class="form-control input-lg" id="name" placeholder="Enter name" required="required" />
</div>
<div class="col-md-6">
<input type="email" class="form-control input-lg" id="email" placeholder="Enter email" required="required" />
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control input-lg" id="subject" placeholder="Subject" required="required" />
</div>
<div class="form-group">
<textarea name="message" id="message" class="form-control" rows="4" cols="25" required="required" placeholder="Message"></textarea>
</div>
<button "style=width:40 height:40" class="btn btn-skin" type="submit" id="btnContactUs">Send Message</button>
</div>
</div>
</form>
</div>
</div>
</div>

You could redirect after the script in mailfunc.php to your index.html like this:
header("Location: index.html");
exit();

Currently your submit will open a POST request to mailfunc.php where your form data (most probably) will be processed.
You can quite easily forward from mailfunc.php to index.html using some Javascript code like:
window.location.href = 'index.html';

Try this.
$referer = $_SERVER['HTTP_REFERER'];
header("Location: $referer");
This helps you to redirect to the same page where you are submitting the form

Google reCaptcha validation on form submit

I am implementing reCaptcha in my website, but i could not validate recaptcha on form submit. The form is getting submitted even if the recaptcha is not clicked. How to check whether the captcha is valid/checked or not The code snippet is :
<div class="form-group">
<div class="input-group">
<input id="mailid" type="email" placeholder="Enter Your Email" class="form-control input-md" required>
</div>
<br>
</div>
<div class="g-recaptcha" data-sitekey="site-key" id="recaptcha"></div> <br>
<div class="btn-group">
<button type="submit" class="btn btn-primary" id="Button1" /><h5>submit</h5>
<button type="submit" class="btn btn-link" id="cancelbtn" /><u>cancel </u>
</div>
</form>
NOTE : We are not using php in the application.

Form gets submitted even if the required fields are left empty in angular JS

I am newbie to angular JS and i have created a form which is
HTML
<div data-ng-controller="ReservationController"
<form class="form-horizontal" role="form">
<div class="form-group">
<div class="col-sm-10">
<label>Guest Name</label>
<input type="text" class="form-control" placeholder="" ng-model="res_guest_name" required>
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>Phone</label>
<input type="phone" class="form-control" ng-model="res_member_phone">
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>FAX</label>
<input type="phone" class="form-control" ng-model="res_member_fax">
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>Email</label>
<input type="email" class="form-control" ng-model="res_member_email" required>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-8 col-sm-10">
<button type="submit" class="btn btn-success" ng-click="res_save()">Save Changes</button>
</div>
</div>
</form>
</div>
CONTROLLER
function ReservationController($scope, $http, $cookieStore,$location,$filter) {
$scope.res_save = function()
{
var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
$http.get(save_res).success(function(response) {
alert('success');
});
}
}
My form gets submitted even after the required fields are left empty. it shows the error, then it gets submitted.

Obviously it will submit the form you didn't handled the submission of form.You just managed the errors :-)
Use ng-disabled="myForm.$invalid"
where myForm is the name field on form
<form class="form-horizontal" name="myForm" role="form">
<button type="submit" class="btn btn-success" ng-disable="myForm.$invalid" ng-click="res_save()">Save Changes</button>
If you don't want the button to be disable till then you can use
<button type="submit" class="btn btn-success" ng-click="res_save(myForm.$valid)">Save Changes</button>
And in controller
$scope.res_save = function(valid)
{
if(valid){
var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
$http.get(save_res).success(function(response) {
alert('success');
});
}
}

You are not checking for Form valid state before saving it , don't expect angular to magically stop saving when form is invalid.

You should look into the documentation for ng-submit. If you move the res_save function into an ng-submit on the form (and removed the ng-click on the submit input) it will validate against required fields, prevent execution of the function until they are valid.
