javascript select2 allowed tags

问题

I need to allow users select ONLY allowed tags in select.

Currently I have that:

$("input#id_txtcolor").select2({tags:["red", "green", "blue"]});

Can you help me please with that?

回答1:

as of 3.3 you can specify your own createSearchChoice when using tags that will always return null, thus preventing the default choice from being created.

$().select2({
    createSearchChoice: function() { return null; },
    tags:...
});

Sometimes we developer don't use our 7th sense that is common sense also happened with me struggled for 2 hours then it clicked my sense.. if you want user to select only allowed values then its no more tagging its selecting So just remove tags:true option and keep mulitple attribute in select, provide options directly in select element or load remote data.
