javascript – How to Automatically Close Alerts using Twitter Bootstrap-ThrowExceptions

Exception or error:

I’m using twitter’s bootstrap CSS framework (which is fantastic). For some messages to users I am displaying them using the alerts Javascript JS and CSS.

For those interested, it can be found here:

My issue is this; after I’ve displayed an alert to a user I’d like it to just go away after some time interval. Based on twitter’s docs and the code I’ve looked through it looks like this is not baked in:

  • My first question is a request for confirmation that this is indeed NOT baked into Bootstrap
  • Secondly, how can I achieve this behavior?
How to solve:

Calling window.setTimeout(function, delay) will allow you to accomplish this. Here’s an example that will automatically close the alert 2 seconds (or 2000 milliseconds) after it is displayed.

window.setTimeout(function() { $(".alert-message").alert('close'); }, 2000);

If you want to wrap it in a nifty function you could do this.

function createAutoClosingAlert(selector, delay) {
   var alert = $(selector).alert();
   window.setTimeout(function() { alert.alert('close') }, delay);

Then you could use it like so…

createAutoClosingAlert(".alert-message", 2000);

I am certain there are more elegant ways to accomplish this.


I could not get it to work with alert.(‘close’) either.

However I am using this and it works a treat! The alert will fade away after 5 seconds, and once gone, the content below it will slide up to its natural position.

window.setTimeout(function() {
    $(".alert-message").fadeTo(500, 0).slideUp(500, function(){
}, 5000);


I had this same issue when trying to handle popping alerts and fading them. I searched around various places and found this to be my solution. Adding and removing the ‘in’ class fixed my issue.

window.setTimeout(function() { // hide alert message

}, 5000);

When using .remove() and similarly the .alert(‘close’) solution I seemed to hit an issue with the alert being removed from the document, so if I wanted to use the same alert div again I was unable to. This solution means the alert is reusable without refreshing the page. (I was using aJax to submit a form and present feedback to the user)

    $('#Some_Button_Or_Event_Here').click(function () { // Show alert message


Using the ‘close’ action on the alert does not work for me, because it removes the alert from the DOM and I need the alert multiple times (I’m posting data with ajax and I show a message to the user on every post).
So I created this function that create the alert every time I need it and then starts a timer to close the created alert. I pass into the function the id of the container to which I want to append the alert, the type of alert (‘success’, ‘danger’, etc.) and the message.
Here is my code:

function showAlert(containerId, alertType, message) {
    $("#" + containerId).append('<div class="alert alert-' + alertType + '" id="alert' + containerId + '">' + message + '</div>');
    $("#alert" + containerId).alert();
    window.setTimeout(function () { $("#alert" + containerId).alert('close'); }, 2000);


This is the coffescript version:

setTimeout ->
 $(".alert-dismissable").fadeTo(500, 0).slideUp(500, -> $(this.remove()))


With each of the solutions above I continued to lose re-usability of the alert. My solution was as follows:

On page load


Once the alert needed to be displayed

 window.setTimeout(function () {
     $("#success-alert").slideUp(500, function () {
 }, 5000);

Note that fadeTo sets the opacity to 0, so the display was none and the opacity was 0 which is why I removed from my solution.


After going over some of the answers here an in another thread, here’s what I ended up with:

I created a function named showAlert() that would dynamically add an alert, with an optional type and closeDealy. So that you can, for example, add an alert of type danger (i.e., Bootstrap’s alert-danger) that will close automatically after 5 seconds like so:

showAlert("Warning message", "danger", 5000);

To achieve that, add the following Javascript function:

function showAlert(message, type, closeDelay) {

    if ($("#alerts-container").length == 0) {
        // alerts-container does not exist, add it
            .append( $('<div id="alerts-container" style="position: fixed;
                width: 50%; left: 25%; top: 10%;">') );

    // default to alert-info; other options include success, warning, danger
    type = type || "info";    

    // create the alert div
    var alert = $('<div class="alert alert-' + type + ' fade in">')
            $('<button type="button" class="close" data-dismiss="alert">')

    // add the alert div to top of alerts-container, use append() to add to bottom

    // if closeDelay was passed - set a timeout to close the alert
    if (closeDelay)
        window.setTimeout(function() { alert.alert("close") }, closeDelay);     


I needed a very simple solution to hide something after sometime and managed to get this to work:

In angular you can do this:


Here is the function that i call when the timeout has been reached

 self.hideError = function(){
   self.HasError = false;
   self.ErrorMessage = '';

So now my dialog/ui can use those properties to hide elements.


With delay and fade :



try this one

$(function () {

 setTimeout(function () {
            if ($(".alert").is(":visible")){
                 //you may add animate.css class for fancy fadeout

        }, 3000)
