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.

Redirecting a modal form to my php script

I'm trying to redirect my modal form to my php script, I've used action but for some reason the button just clicks and stops.
<form action="action.php" method="post" role="form" target="action.php">
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input class="form-control" id="exampleInputEmail1" placeholder="Enter email" type="email" />
</div>
<div class="form-group">
<label for="exampleInputPassword1">Password</label>
<input class="form-control" id="exampleInputPassword1" placeholder="Password" type="password" />
</div>
<!-- Form submit button -->
<button class="btn btn-primary" data-target="action.php" data-toggle="button" type="submit">Submit</button>
</form>
</div> <!-- opened somewhere else -->
</div> <!-- opened somewhere else -->
<p>
<!-- Opens the modal -->
<button class="btn btn-light" data-target="#surveymodal" data-toggle="modal" type="button">Submit</button>
<script src="assets/js/jquery.min.js"></script>
<script src="assets/js/popper.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
</p>
</body>
</html>

Your submit button's type seems to be incorrect:
<p><button class="btn btn-light" data-target="#surveymodal" data-toggle="modal" type="submit">Submit</button><script src="assets/js/jquery.min.js"></script><script src="assets/js/popper.js"></script><script src="bootstrap/js/bootstrap.min.js"></script></p>
Fix above.

My angular form validation doesn't work

I use bootstrap with angular, and I disabled bootstrap's validation, angular still doesn't work. It seems that I already set everything.
My code likes below, every input's validation didn't.
<form novalidate name="new_people" ng-if="is_editting_newpeople" class="form-horizontal" role="form" ng-submit="save_new_people()">
<div class="input-group">
<div class="input-group-addon">True Name</div>
<input class="form-control" name="realname" type="text" ng-model="editting_people.realname" autofocus required>
</div>
<div class="input-group">
<div class="input-group-addon">Nickname</div>
<input type="text" name="nickname" class="form-control" id="nickname" ng-model="editting_people.nickname" required>
</div>
<div class="input-group">
<div class="input-group-addon">Mobilenumber</div>
<input type="text" class="form-control" id="mobile" name="mobilenumber" ng-model="editting_people.mobilenumber" required ng-minlength=11>
</div>
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-default
dropdown-toggle" data-toggle="dropdown">{{ editting_people.idclass.name }}
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li ng-repeat="id_class in IDCLASSES">
<a ng-click="set_id_class(id_class)">{{ id_class.name }}</a>
</li>
</ul>
</div>
<!-- /btn-group -->
<input type="text" class="form-control" ng-model="editting_people.idnumber" required name="idnumber">
</div>
<!-- /input-group -->
<br>
<input class="btn btn-primary" type="submit" value="Submit" />
<input class="btn btn-default" value="取消" type="button" ng-click="cancel_new_people()" />
</form>

What do you mean by input doesn't work?
Post your code of related controller please, because it is not clear what validation are you doing. If you have novalidate you should organize validation in your angular controller or HTML, e.g.:
<div ng-show="editting_people.realname.length<4">
Any error message here.

Can't Implement the Modal in Bootstrap

i am newbie.
I am Creating a button on my homepage,once clicked it shows a modal showing the signin form and i am making a separate html page for my Modal.
Here is my Main Code where the Button is placed in my homepage.
<button id="btn1"><a href="signin.html" class="btn btn-success"data-toggle="modal"data-target="#mymodal"type="button">
<span class="glyphicon glyphicon-edit">
</span> Sign In</a>
</button>
In signin.html
<div class="modal"id="mymodal" >
<h3 class="modal-header">
<h1>
We Are Glad you are Here!
</h1>
</div>
<div class="modal-body">
<div class="container">
<form class="form-signin">
<h6 class="form-signin-heading">
Please sign In</p>
<label for="inputEmail" class="sr-only">Email address</label>
<input type="email" id="inputEmail" class="form-control" placeholder="Email address" required autofocus>
<label for="inputPassword" class="sr-only">Password</label>
<input type="password" id="inputPassword" class="form-control" placeholder="Password" required>
<div class="checkbox">
<label>
<input type="checkbox" value="remember-me"> Remember me
</label>
</div>
<button class="btn btn-sm btn-primary" type="submit" data-toggle="modal">Sign in</button>
</form>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal"aria-hidden="true">Close</button>
</div> </div>
Issue
Modal ain't popping up on same page but it's going on next page.How should i fix it?so that my Signup form remains on the front page.

Working Example
I think the target element with the id mymodal should be in the same page with button, try to place <div class="modal"id="mymodal" ></div> after the button :
<button id="btn1">
<a href="signin.html" class="btn btn-success" data-toggle="modal"
data-target="#mymodal"type="button">
<span class="glyphicon glyphicon-edit"></span> Sign In
</a>
</button>
<div class="modal"id="mymodal" ></div> //place the target div after button
Hope this helps.
