node.js - DatePicker jquery UI not workinng
For whom run into the same problem, this is the reference.
I finally found the answer by checking the code.I was unable to load JQuery for in the layout.ejs, I retyped the following in order to load the bootstrap, but actually by using https://npmjs.org/package/twitter-bootstrap-node twitter-bootstrap-node, there is no-need to load the javascripts again. This may be a common problems for beginners in Node.JS like me.Hope this answer can be helpful to people who run into the same problem and the code is in the answer of the related problem.
<script src="/javascripts/jquery.js"></script>
<script src="/javascripts/bootstrap.js"></script>
<script src="/vendor/twitter/less/bootstrap.less"></script>
