Introduction
Hey Ninjas! You must have heard about the Bootstrap framework in your programming world. While styling any web page, we need alerts to show the critical message to the user. Do you know how to add these alerts? If not, then welcome to the Bootstrap alert plugins blog.
We will discuss the Bootstrap alert plugins in detail. Let's start without wasting time.
Bootstrap Alert Plugin
Alert plugins display information such as warning or success messages to the users. Using the alert message plugin, you can add the dismiss feature to all alert messages. Alert.js is required if you want to include this plugin's functionality individually. Else, you can include bootstrap.js, as mentioned in the Bootstrap Alerts blog.
Types of Alerts
Let's take a quick working example for the danger alert using the ‘.alert’ class.
As you can see in the output, the dismissing alert added a cross (x) on the rightmost corner of the given alert so the user can remove the alert from the screen if they want.
Javascript
To automatically close the functionality to dismiss using Javascript, add $("alert").alert() to your close button.
Let's take a look at the example given below.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>Bootstrap Alert Plugin</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/css/bootstrap.min.css"/>
<script src="https://code.jquery.com/jquery-3.6.0.slim.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/js/bootstrap.min.js"></script>
</head>
<body>
<h4>Bootstrap Dismissal Alert</h4>
<div class="alert alert-success alert-dismissible fade show mx-1 mt-1 border border-success"
role="alert">
<b>Successfull! Congratulations, you learnt how to show a dismissal alert in bootstrap</b>
<button
type="button"
class="btn bg-warning ml-4"
onclick="onButtonPress()">
×
</button>
</div>
<script>
function onButtonPress() {
$(".alert").alert("close");
}
</script>
</body>
</html>
Output:
We can dismiss the warning alert by clicking on the cross button in the right corner.
Methods
In Bootstrap alert plugins, there are two methods which are mentioned below. Let's discuss them.
.alert() method
.alert('close') method
.alert()
The .alert() method wraps all alerts with a close functionality. In simpler words, it will add a close icon (x) to the alert. Let's check this out using an example.
You can see the cross button in the above output, but it will not work by just using the .alert() method. We have to give a few more directions to the model. Let's check those directions in the next section.
.alert('close')
The .alert('close') method will enable the function of the cross button to close the alert message. Let's check the code. We will use the same example used in the .alert() method for better understanding.
Now, you will able to remove the alerts by clicking on the close button.
Events
Bootstrap modal events are a collection of Javascript that enable you to start Bootstrap modals in response to a user action. There are two types of events which are mentioned below.
close.bs.alert
The close.bs.alert event occurs instantly when the close instance method is called. Let's take a look at the example given below.
Both examples of the events are the same. The only difference is closed.bs.alert waits for the CSS transition to over, but the close.bs.alert dismiss the alert message instantly after clicking the close button.
