How to add success notification after form submit

I would like to add success notification after user submitted the form.

I've already checked out the Pnotify js library -https://sciactive.com/pnotify/, which looks nice. But no idea how I can use in my CRUD project. I'm using Spring Boot and Thymeleaf for a frontend.

I checked docs:

<button class="btn btn-default source" onclick="new PNotify({
                              title: 'Regular Success',
                              text: 'That thing that you were trying to do worked!',
                              type: 'success',
                              styling: 'bootstrap3'
                          });">Success</button>

This is my form:

<form action="#" th:action="@{/contractors-save}"
    th:object="${contractor}"
    method="post" class="form-horizontal form-label-left">

<div class="form-group">
    <label class="control-label col-md-3 col-sm-3 col-xs-12">Name</label>
    <div class="col-md-5 col-sm-5 col-xs-12">
        <input type="text" th:field="*{name}" class="form-control"
                placeholder="name"/>
    </div>
</div>

<div class="form-group">
    <label class="control-label col-md-3 col-sm-3 col-xs-12">Description</label>
    <div class="col-md-5 col-sm-5 col-xs-12">
        <input type="text" th:field="*{description}"
                class="form-control"
                placeholder="description"/>
    </div>
</div>

<div class="modal-footer">
    <button type="button" class="btn btn-default"
            data-dismiss="modal">
        Close
    </button>
    <input type="submit" value="Save" class="btn btn-success">
</div>

The notification is showing on click action, in my case I need to show after form submission. Could you advise and share with your expertise? Maybe other alternatives.

I followed PRG pattern, as @Minar Mahmud suggested, will share with my implementation:

Controller:

@RequestMapping(value = "/contractor-save", method = RequestMethod.POST)
public String saveContractor(@ModelAttribute(value = "contractor") Contractor contractor,
                         RedirectAttributes redirectAttributes) {
    Contractor savedContractor = contractorService.save(contractor);
    redirectAttributes.addFlashAttribute("notification",
        String.format("Contractor \"%s\" successfully saved", savedContractor.getName()));
    redirectAttributes.addFlashAttribute("action", "save");

return "redirect:/contractors";

}

And in HTML file, showing notification on page load with javascript:

<script th:inline="javascript">
$(document).ready(function () {
    var notification = /*[[${notification}]]*/ "";
    var action = /*[[${action}]]*/ "";
    if (action === 'save') {
        new PNotify({
            title: 'Save contractor',
            text: notification,
            type: 'success',
            styling: 'bootstrap3',
            delay: 3000
        });
    } else if (action === 'remove') {
        new PNotify({
            title: 'Remove contractor',
            text: notification,
            type: 'success',
            styling: 'bootstrap3',
            delay: 3000
        });
    } else if (action === 'update') {
        new PNotify({
            title: 'Edit contractor',
            text: notification,
            type: 'success',
            styling: 'bootstrap3',
            delay: 3000
        });
    }
});

Please fill free to comment. I would like to know is it ok for production? Just to be sure that I'm not reinventing the wheel.

Here is an alternative.

You can follow PRG pattern and use RedirectAttributes to add flash attributes.

For example:

@RequestMapping(value = "/contractor", method = RequestMethod.POST)
public String handle(@Valid @ModelAttribute Contractor contractor,
                     BindingResult result,
                     RedirectAttributes redirectAttributes) {

    // Save contactor ...

    redirectAttributes.addFlashAttribute("message", "Successful!");

    return "redirect:/someGetUrl";
}

And just show this message in the view rendered by /someGetUrl handler.
