My Dijit DateTimeCombo widget doesn't send selected value on form submission
- by david bessire
i need to create a Dojo widget that lets users specify date & time. i found a sample implementation attached to an entry in the Dojo bug tracker. It looks nice and mostly works, but when i submit the form, the value sent by the client is not the user-selected value but the value sent from the server.
What changes do i need to make to get the widget to submit the date & time value?
Sample usage is to render a JSP with basic HTML tags (form & input), then
dojo.addOnLoad a function which selects the basic elements by ID, adds dojoType
attribute, and dojo.parser.parse()-es the page.
Thanks in advance.
The widget is implemented in two files. The application uses Dojo 1.3.
