Hey,everyone,

I encountered a problem when getting a date through calendar date  
select plugin. It’s convenient to put the very  
tag(calendar\_date\_select\_tag) in a form, then get the date when the  
form is submitted, however, if I don’t put the  
calendar\_date\_select\_tag in a form, and just use it as an element  
which can show a calendar on the page, now I wanna update a specific  
area on the page when my mouse goes over the date on the calendar. so  
far, the trouble is I can not fetch the datetime in an onchange event?  
My code is as below:

 \<%= calendar\_date\_select\_tag :e\_date, nil, :embedded =\> true, :year\_range =\> 100, :month\_year =\> "label", :onchange =\> remote\_function(:update=\>"events", :url=\>study\_plan\_users\_calendars\_path) %\>

Here comes the message which is updated according to the date

How can I get the datetime which is used as some condition when  
updating the specific area?  
Or any other idea on solving this updating issue?
