Usage

The users parameter accepts an array of objects. Each object must have a username key in order for this script to work.

$("#multi-users").mention({
    delimiter: '@',
    users: [{
        username: "ashley"
    }, { 
        username: "roger"
    }, { 
        username: "frecklefart123"
    }]
});

Sensitivity

$("#multi-users").mention({
    sensitive: true,
    users: [{
        username: "sarah"
    }, { 
        username: "bigRat"
    }, { 
        username: "roger"
    }, { 
        username: "Ricky"
    }]
});

With sensitivity set to true, items are ordered by the following divisions of priority:

Highest: If first letter matches exactly
High: If first letter matches regardless of case
Med: If target has matching letters’ case
Low: if target has matching character regardless of case

Sensitivity Examples:

If you were to query "@r", with sensitivity on, the resulting list will be ["roger", "Ricky", "sarah", "bigRat"], but if you were to query "@R", the resulting list would be ["Ricky", "roger", "bigRat", "sarah"]

Full Names, Images, and Query By

If you have a name and/or image key in one of your user objects, there name and image will appear as such in the dropdown list.

The queryBy parameter accepts an array of strings that represent keys in your user object that you would like to query against. For example, if you were to type in the name “@Scott”, the script would match the username “@bigCat”. username is required for this script to work.

$("#multi-users").mention({
    queryBy: ['name', 'username'],
    users: [{
        username: "sarah",
        name: "Sarah Jones",
        image: "http://placekitten.com/25/25"
    }, { 
        username: "bigCat",
        name: "Scott Pfaff",
        image: "http://placekitten.com/25/25"
    }, { 
        username: "coderDude",
        name: "Roger Penn",
        image: "http://placekitten.com/25/25"
    }]
});

Empty Querying

You may query for users simply by pressing your delimiter. For example, pressing the @ symbol will return all users that are a part of your users list, so long as those users adhere to the typeaheadOpts.items limit

$('#multi-users').mention({
    emptyQuery: true,
    typeaheadOpts: {
        items: 10 // Max number of items you want to show
    },
    users: [...]
});

Defaults

$("#multi-users").mention({
    users: [], // Array of Objects
    delimiter: '@', // Username Delimiter
    sensitive : true,
    queryBy: ['name', 'username'],
    typeaheadOpts: { // Settings for Typeahead
        matcher: _matcher, // Mention.js's custom matcher function, don't change
        updater: _updater, // Mention.js's custom updater function, don't change
        sorter: _sorter, // Mention.js's custom sorter function, don't change
    }
});
