Using the alert JavaScript plugin, it’s possible to dismiss any alert inline. Here’s how:
.alert-dismissible class, which adds
extra padding to the right of the alert and positions the close button.
data-mdb-dismiss="alert" attribute,
which triggers the JavaScript functionality. Be sure to use the
button element with it for proper behavior across all devices.
.fade and .show classes.
You can see this in action with a live demo:
Holy guacamole! You should check in on some of those
fields below.
You can manually show alert using show() method.
Hidden alert!
mdb.Alert.getInstance(document.getElementById('show-example')).show();
You can manually hide alert using hide() method.
Hide me!
mdb.Alert.getInstance(document.getElementById('hide-example')).hide();
You can set the position of every alert using the
data-mdb-position attribute.
Select horizontal / vertical alignment
Show me wherever you want!
mdb.Alert.getInstance(document.getElementById('placement-example')).show();
You can display an alert anywhere. Just put it in your target element and fill
the
data-mdb-container attribute with id or class of parent.
Hello from parent element!
mdb.Alert.getInstance(document.getElementById('container-example')).show();
You can set offset of your alert using a data-mdb-offset tag.
Offset: 100px
mdb.Alert.getInstance(document.getElementById('offset-example')).show();
You can turn on stacking your alerts using the
data-mdb-stacking attribute.
let alertCount = 0;
function* colorGenerator(i) {
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
while (true) {
yield colors[i];
i++;
if (i > colors.length - 1) {
i = 0;
}
}
}
const colorIterator = colorGenerator(0);
document.getElementById('stacking-trigger-example').addEventListener('click', () => {
alertCount++;
color = colorIterator.next().value;
const alert = document.createElement('div');
alert.innerHTML = `
${alertCount}. Stacking alerts
`;
alert.classList.add('alert', 'fade');
document.body.appendChild(alert);
const alertInstance = new mdb.Alert(alert, {
color,
stacking: true,
hidden: true,
width: '450px',
position: 'bottom-right',
autohide: true,
delay: 5000,
});
alertInstance.show();
});
You can also stack alerts inside the container
let alertCount = 0;
function* colorGenerator(i) {
const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];
while (true) {
yield colors[i];
i++;
if (i > colors.length - 1) {
i = 0;
}
}
}
const colorIterator = colorGenerator(0);
document
.getElementById('stacking-container-trigger-example')
.addEventListener('click', () => {
alertCount++;
color = colorIterator.next().value;
const alert = document.createElement('div');
alert.innerHTML = `
${alertCount}. Stacking alerts
`;
alert.classList.add('alert', 'fade');
document.getElementById('parent-stacking-container-example').appendChild(alert);
const alertInstance = new mdb.Alert(alert, {
color,
stacking: true,
container: '#parent-stacking-container-example',
hidden: true,
width: '250px',
position: 'top-right',
autohide: true,
delay: 5000,
});
alertInstance.show();
});
