Answer 1

It is because of you are trying to post the data to form .
If you use button type = "submit" it will redirect you to somewhere .
You should avoid using type = "submit" .
Instead use the type = "button"
<button type = "button" class="btn btn-secondary btn-lg shadow-lg rounded" value="ADD" id="add-data"> <span class=" fa fa-plus"> </span> ADD</button>
And achieve it by using click event of the button .
then get it in jquery .
$("#add-data").click(function (event) {
//Your code here
}

You can try this instead of prevent default. The reload happen, because you use form submit event.
$('#add-data').submit(false);
If you want to use prevent default, then use click event of the submit button to perform the action.
$("#add-data").click(function (event) {
event.preventDefault();
$.ajax({
type: "POST",
url: "teachers",
dataType: 'json',
headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
data: $(this).serialize(),
success: function (data) {
alert("Added");
},
});
}

Answer 3

Remove dataType: 'json' as you're already returning JSON otherwise your button seems perfect.
Try this
jQuery(document).ready(function($) {
$("#add-data").submit(function(e){
e.preventDefault();
$.ajax({
type: "POST",
url: "teachers",
headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
data: $(this).serialize(),
success: function (data) {
alert("Added");
},
});
});
});

Add "return false;" in the end of your submit callback..
As "add-data" is ID of your button, for your example it couldn't retrieve a submit event. That's because it submitted and didn't prevented.
So you can write something like this:
$("form").submit(function (event) {
event.preventDefault();
$.ajax({ ... });
return false; // <<< THE THING
});
Or just do that with binding an click event on button (not for submit event on button)
$("#add-data").click(function (event) {
event.preventDefault();
$.ajax({ ... });
});
With this you can leave button type, and don't need to change that to type="button".
