Show Custom Modal

I have bootstrap modal which is not hidden. I mean there is no fade class which is generally seen as <div class="modal fade" role="dialog">. I want to show modal as popup when user clicks on button. The code below does not work as it is unable to detect it as modal.
JS
$(function(){
$('.custom-modal').click(function(e){
e.preventDefault();
var mymodal = $('#myModal');
mymodal.modal('show');
});
})
HTML
<button class="btn btn-primary btn-lg custom-modal">Open Modal</button>
<div id="myModal">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Error</h4>
</div>
<div class="modal-body">
<p> </p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>

Can you please check the below code? Hope it will work for you. You just need to add class="modal fade" with id="myModal" and it will work perfectly.
Please refer to this link: https://jsfiddle.net/yudizsolutions/2qfeagc5/
$(function() {
$('.custom-modal').click(function(e) {
e.preventDefault();
var mymodal = $('#myModal');
mymodal.modal('show');
});
})

How to display information from input fields in a bootstrap modal?

So once the user has filled out their information and clicks submit I want to display the information in a bootstrap model with a confirmation button underneath.
This would be a summary of their information before it submitted to the database. So far here's what I've got:
const text = document.getElementsByClassName("myText").innerHTML;
const modalBody = document.getElementById("bodyModal")
function submitText () {
modalBody.innerHTML = text
}

You need to get the value of the input fields. I suggest giving the inputs two ids like this:
<label for="id1">Name</label>
<input type="text" class="myText" id="id1">
<label for="id2">Age</label>
<input type="text" class="myText" id=id2">
and then get their value with:
var name = document.getElementById("id1").value
var age = document.getElementById("id2").value
Finally, you can append the text you just got on the modal by doing so:
$("#bodyModal").html("<p>"+name+"</p><p>"+age+"</p>")

bootstrap modal form not submitted the user In rails 5

I have form inside modal and want to create a user. when I click on submit nothing happens.
How can I submit the modal form and save the content of the modal in other page in rails application with Ajax?
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="#getbootstrap">Open modal for #getbootstrap</button>
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">New message</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="text" class="col-form-label">firstname:</label>
<input class="form-control" id="text2"></input>
</div>
<label for="text" class="col-form-label">lastname:</label>
<input class="form-control" id="text2"></input>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data- dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">submit</button>
</div>
</div>

By clicking submit button the text field value will be passed to the controller via Ajax method
$(document).ready(function(){
$("#submit").click(function(){
alert($("#name").val());
});
$.ajax({
type: 'POST',
url: 'path/to/controller',
data: {'value' : $("#name").val() }
});
});

Any idea for help me. Thanks!

You need to hide the modal, wait for the animation to complete, and then scroll to the item.
You can optionally animate the scroll with $('html,body').animate({scrollTop: $('#Content').offset().top)});
function onContentClick(e) {
e.preventDefault();
$('#myModal').one('hidden.bs.modal', () =>
window.scrollTo(0, $('#Content').offset().top));
$('#myModal').modal('hide');
}
#Content {
height: 400px;
margin-top: 1000px;
background: red;
}

define onclick function to both buttons and pass this as parameter and then use next() property of jquery
<button type="button" class="btn btn-info btn-lg" onclick="firstmodal(this)" >Open Modal 1</button>
<!-- Modal -->
<div class="modal fade" role="dialog">
<div class="modal-dialog">

<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
js
function firstmodal(ele){
$(ele).next().modal('show');
}
Do the same for other modal as well

$(document).ready(function(){
var buttons = $(".container button");
if(buttons.length > 0){
buttons[0].on("click", function(){
//this will return two modals
var modals = $(".container div.modal")
if(modals.length > 0){
modals[0].modal("toggle");
}
})
}
if(buttons.length > 1){
buttons[1].on("click", function(){
//this will return two modals
var modals = $(".container div.modal")
if(modals.length > 1){
modals[1].modal("toggle");
}
})
}
})
Hope that solves the problem
