Dynamic content in EJ2 JavaScript Badge control
13 Jan 202514 minutes to read
Badges often need to be updated dynamically based on real-time requirements. The following sample demonstrates how to update badge content dynamically. Click the increment button to change the badge value.
// Datasource for ListView, badge field is the class data for Badge
var dataSource = [
{ id: 'p_01', text: 'Primary', messages: '3 New', badge: 'e-badge e-badge-primary', icons: 'primary', type: 'Primary' },
{ id: 'p_04', text: 'Updates', messages: '13 New', badge: 'e-badge e-badge-info', icons: 'updates', type: 'Primary' },
{ id: 'p_05', text: 'Starred', messages: '', badge: '', icons: 'starred', type: 'All Labels' },
{ id: 'p_06', text: 'Important', messages: '2 New', badge: 'e-badge e-badge-danger', icons: 'important', type: 'All Labels' },
{ id: 'p_09', text: 'Drafts', messages: '7 New', badge: 'e-badge e-badge-warning', icons: 'draft', type: 'All Labels' },
];
var list = new ej.lists.ListView({
// Bind ListView datasource
dataSource: dataSource,
// Assign header title
headerTitle: 'Inbox',
// Enable header
showHeader: true,
// Assign template
template: '<div class="listWrapper" style="width: inherit;height: inherit;"><span class="${icons} list_svg"> </span>' +
'<span class="list_text">${text} </span>' +
'${if(messages !== "")}<span class="${badge}" style="float: right;margin-top: 16px;font-size: 12px;">${messages}</span>${/if}</div>',
// Map fields
fields: { groupBy: 'type' },
// Bind actionComplete event
actionComplete: () => {
badgeElements = Array.prototype.slice.call(document.getElementById('lists').getElementsByClassName('e-badge'));
}
});
list.appendTo('#lists');
document.getElementById('button').addEventListener('click', function buttonClick() {
badgeElements.forEach((element) => {
element.textContent = (Number(element.textContent.split(' ')[0])) + 1 + ' New';
})
});<!DOCTYPE html>
