how to use bootstrap alert message inside a javascript function?

Question

I would like to add Bootstrap alert messages inside the JavaScript function.

Eg:

<div class="alert alert-success fade in">
     <a href="#" class="close" data-dismiss="alert">&times;</a>
     <strong>Success!</strong> Your message has been sent successfully.
</div>

The above div content displays a success message. I want to call this inside my JavaScript code, if my web service returns a success message.

Answer 1

You can set toggle your web service returns. This example working with click function.

 function toggleAlert(){ $(".alert").toggleClass('in out'); return false; // Keep close.bs.alert event from removing from DOM } $("#btn").on("click", toggleAlert); $('#bsalert').on('close.bs.alert', toggleAlert) 

 <link rel="stylesheet" type="text/css" href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script> <button id="btn">Toggle</button> <div class="alert alert-info fade out" id="bsalert"> <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a> <strong>Info!</strong> This alert box could indicate a neutral informative or action </div> <div> content 

Answer 2

Create a class to initially hide the alert

.hide{
  display:none
}

<div id = "alertId" class="alert alert-success fade in hide">
       //rest of code
</div>

In js in the success function

 document.getElementById('alertId').classList.remove('hide')

Answer 3

 $("#success-alert").hide(); $("#test").click(function showAlert() { $("#success-alert").fadeTo(2000, 500).slideUp(500, function(){ $("#success-alert").slideUp(500); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.1.1/js/bootstrap.min.js"></script> <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.1.1/css/bootstrap.min.css"> <div> <button id="test">Result</button> </div> <div class="alert alert-success" id="success-alert"> <a href="#" class="close" data-dismiss="alert">&times;</a> <strong>Success!</strong> Your message has been sent successfully. </div> 

You can use the above snippet code, but place the code in button .click() event after the return of the server result.
