FAQ

How can I prevent duplicate tokens from being entered?

You can use the tokenfield:createtoken event for that. Check the event.attrs property for token value and label, and the run your duplicate detection logic. If it's a duplicate token, simply do event.preventDefault().

Here's a simple example that checks if token's value is equal to any of the existing tokens' values.

$('#my-tokenfield').on('tokenfield:createtoken', function (event) {
	var existingTokens = $(this).tokenfield('getTokens');
	$.each(existingTokens, function(index, token) {
		if (token.value === event.attrs.value)
			event.preventDefault();
	});
});

And how about limiting tokens to my typeahead/autocomplete data?

Similarly, using tokenfield:createtoken, you can check to see if a token exists in your autocomplete/typeahead data. This example checks if the given token already exists and stops its entry if it doesn't.

$('#my-tokenfield').on('tokenfield:createtoken', function (event) {
	var available_tokens = bloodhound_tokens.index.datums
	var exists = true;
	$.each(available_tokens, function(index, token) {
		if (token.value === event.attrs.value)
			exists = false;
	});
	if(exists === true)
		event.preventDefault();
})
