How to open a Bootstrap modal using jQuery? - bootstrap-modal

Question

I'm using Twitter Bootstrap modal window functionality. When someone clicks submit on my form, I want to show the modal window upon clicking the "submit button" in the form.
<form id="myform" class="form-wizard">
<h2 class="form-wizard-heading">BootStap Wizard Form</h2>
<input type="text" value=""/>
<input type="submit"/>
</form>
<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary">Save changes</button>
</div>
</div>
$('#myform').on('submit', function(ev) {
$('#my-modal').modal({
show: 'false'
});
var data = $(this).serializeObject();
json_data = JSON.stringify(data);
$("#results").text(json_data);
$(".modal-body").text(json_data);
// $("#results").text(data);
ev.preventDefault();
});
I have check demo from this website

There was some missing divs in your modal that I have included below (modal-dialog and modal-content classes)
Also added a name attribute to your input so you can serialize it with serialize() according to https://api.jquery.com/serialize/
$('#myform').on('submit', function(ev) {
$('#myModal').modal('show');
var data = $(this).serialize();
json_data = JSON.stringify(data);
$("#results").text(json_data);
$(".modal-body").text(json_data);
// $("#results").text(data);
ev.preventDefault();
});
