How to use alerts in the bootstrap?


Alerts

Alerts are used for showing notifications and alerts in the browser.

 
<h5><b>Alerts</b></h5>
    <p>Alerts using contextual colors</p>
    <div class="container">
        <div class="alert alert-success">techfunda</div>
        <div class="alert alert-warning">dotnetfunda</div>
        <div class="alert alert-danger">itfunda</div>
        <div class="alert alert-info">kidsfunda</div>
        <div class="alert alert-warning">farmingfunda</div>
        <div class="alert alert-default">fundoovideo</div>
    </div>

In the above code snippetwe are using how to create the alert using contextual classes 

<alert alert danger>-renders the alert with the danger class

<alert alert primary>-renders the alert with the primary class

<alert alert sucess>-renders the alert with the sucess class

<alert alert warning>-renders the alert with the warning class

<alert alert info>-renders the alert with the info class

<alert alert default>-renders the alert with the default class

Closing and linked Alerts:

Alerts are also used as closing alerts.

<h5><b>Closed and Linked alerts</b></h5>
    <p> Closing Alerts with contextual colors</p>
    <div class="container">
        <div class="alert alert-success">
            techfunda
            <a href="#" class="close" data-dismiss="alert"> &times;</a>
        </div>
        <div class="alert alert-danger">
            dotnetfunda
            <a href="#" class="close" data-dismiss="alert">&times;</a>
        </div>
    </div>

Closing and linked alerts

In the above code snippet we have defined how to close the alerts. we have taken section as container and in that container we are having class as alert alert success as techfunda and in the next line we are haing <a>link closing alert we are having class as close and data-dismiss as alert, It dismiss the alert and &times; renders closing symbol.

Alerts with Data -Attributes

We can also use other data attributes such as buttons, span etc. for alerts. take a look at the below code in which we are using span and button instead of 'a' tag.

<h5><b>Alerts using Data attributes</b></h5>
    <p>We can also usedataattributes for the alerts</p>
    <div class="alert alert-warning">
        <button type="button" class="close" data-dismiss="alert">&times;</button>
        <strong>Warning!</strong> This alert is using Button to close.
    </div>
    <div class="alert alert-warning">
        <span class="close" data-dismiss="alert">&times;</span>
        <strong>Warning!</strong> This alert is using Span to close.
    </div> 

Alerts using Data attributes

In the above code snippet we are using alerts with the class buttons and span as class =close and datadismiss  as alert, but there will be no change in using alert operations.

 <button type="button" class="close" data-dismiss="alert">&times;</button>  -renders the button alert

 <span class="close" data-dismiss="alert">&times;</span>-renders with span alert.

        $("#Success").on('close.bs.alert', function () {
            alert("This Alert box is being closed.");
        });
    });
    </script>
    <div class="alert alert-danger" id="Success">
        <a href="#" class="close" data-dismiss="alert">&times;</a>
