How to Automatically Close Alerts using Twitter Bootstrap

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.

$(".alert-message").alert();
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.
