2 May 20234 minutes to read
A particular character in a text can be underlined in the beforeItemRender
event by adding <u>
tag in between the text and assign the innerHTML to the li
element.
In the following example, the first character in File
, Open
, and Save
menu items are underlined.
ej.base.enableRipple(true);
//Menu datasource
var menuItems = [
{
text: 'File',
iconCss: 'em-icons e-file',
items: [
{ text: 'Open', iconCss: 'em-icons e-open' },
{ text: 'Save', iconCss: 'e-icons e-save' },
{ separator: true },
{ text: 'Exit' }
]
},
{
text: 'Edit',
iconCss: 'em-icons e-edit',
items: [
{ text: 'Cut', iconCss: 'em-icons e-cut' },
{ text: 'Copy', iconCss: 'em-icons e-copy' },
{ text: 'Paste', iconCss: 'em-icons e-paste' }
]
},
{ text: 'Format' },
{ text: 'View' },
{ text: 'Bookmarks' },
{ text: 'Tools' },
{ separator: true },
{ text: 'Help' }
];
// Initialize Menu component.
var menuObj = new ej.navigations.Menu({
items: menuItems,
beforeItemRender: function (args) {
if (['File', 'Open', 'Save'].indexOf(args.item.text) > -1) {
// To underline a First character.
var underlinedText = '<u>' + args.item.text.slice(0, 1) + '</u>' + args.item.text.slice(1);
args.element.innerHTML = args.element.innerHTML.replace(args.item.text, underlinedText);
}
}
}, '#menu');
