问题
I installed the "selectize-rails" gem into my rails app, and I'm trying to get it to work. I keep getting this error in my web console:
TypeError: $(...).selectize is not a function
and nothing happens in the browser. Here's the code I have so far, following the "Email Contacts" example from this page: http://brianreavis.github.io/selectize.js/
views/emails/new.html.erb
<script type="text/javascript">
$(document).ready(function() {
console.log( typeof $.fn.selectize === 'function'); // true
console.log( $('#select-to').length === 1 ); // true
var REGEX_EMAIL = '([a-z0-9!#$%&\'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+/=?^_`{|}~-]+)*@' + '(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)';
$('#select-to').selectize({
persist: false,
maxItems: null,
valueField: 'email',
labelField: 'name',
searchField: ['name', 'email'],
options: [
{email: 'brian@thirdroute.com', name: 'Brian Reavis'},
{email: 'nikola@tesla.com', name: 'Nikola Tesla'},
{email: 'someone@gmail.com'}
],
render: {
item: function(item, escape) {
return '<div>' +
(item.name ? '<span class="name">' + escape(item.name) + '</span>' : '') +
(item.email ? '<span class="email">' + escape(item.email) + '</span>' : '') +
'</div>';
},
option: function(item, escape) {
var label = item.name || item.email;
var caption = item.name ? item.email : null;
return '<div>' +
'<span class="label">' + escape(label) + '</span>' +
(caption ? '<span class="caption">' + escape(caption) + '</span>' : '') +
'</div>';
}
},
createFilter: function(input) {
var match, regex;
// email@address.com
regex = new RegExp('^' + REGEX_EMAIL + '$', 'i');
match = input.match(regex);
if (match) return !this.options.hasOwnProperty(match[0]);
// name <email@address.com>
regex = new RegExp('^([^<]*)\<' + REGEX_EMAIL + '\>$', 'i');
match = input.match(regex);
if (match) return !this.options.hasOwnProperty(match[2]);
return false;
},
create: function(input) {
if ((new RegExp('^' + REGEX_EMAIL + '$', 'i')).test(input)) {
return {email: input};
}
var match = input.match(new RegExp('^([^<]*)\<' + REGEX_EMAIL + '\>$', 'i'));
if (match) {
return {
email : match[2],
name : $.trim(match[1])

alert('Invalid email address.');
return false;
}

});

Does anyone who has used Selectize know what I might be missing?
UPDATE:
It gets weirder: Error-prone code randomly started working, but then broke again upon refresh
回答1:
I think you have a jQuery dependency issue caused by the jQuery-rails gem. Try this:
1) Comment out this line in your Gemfile
gem 'coffee-rails', '~> 4.0.1'
#gem 'jquery-rails', '~> 2.3.0'
gem 'turbolinks', '~> 1.1.1'
2) Run bundle install
3) Download this version of jQuery and put in in your vendor/assets/javascript folder.
EDIT
To migrate to the non-gem version place these files in the following paths:
- vendor/assets/stylesheets/selectize.css
- vendor/assets/javascript/selectize.min.js
- vendor/assets/javascript/sifter.js
- vendor/assets/javascript/microplugin.js
回答2:
For me, the issue was that my application code was being included before selectize.js. Adding //= require selectize to app/assets/javascripts/application.js before //= require_tree . fixed it.
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require selectize
//= require_tree .

I had resolved same issue by removing jQuery include, that was included twice. There's note about that in the comments, but it's collapsed and I figured that out myself. Posting this as answer for people to notice it.
