Hi I’m new to javascript and dojo. I’m trying to use two dijit DateTextBoxes with the drop-down calendars to establish a date range for a query on a database. I want to restrict the dates available, once the begin or end date has been selected, so that its impossible to pick an end date that is chronologically before the begin date, and vice versa. I’m trying to apply the example called ‘changing constraints on the fly’ (about half way down the page) from the dojo reference here: http://dojotoolkit.org/reference-guide/dijit/form/DateTextBox.html However, the constraints aren’t working in my code. The only thing I’m really doing differently is using thetundra theme. Any suggestions would be greatly appreciated.

With the new, HTML5-conform attribute
data-dojo-typeintroduced in Dojo 1.6, the way how widget attributes are parsed has changed as well (to validate in HTML5 too). Widget-specific attributes are now in an HTML attribute calleddata-dojo-props, in a JSON-style syntax.To make your example work again, either put the
onChange(andrequired) indata-dojo-props(note that you have to wrap a function around it):Or you use the old
dojoTypeinstead ofdata-dojo-type, then theonChangeattribute would be parsed. Note that it would not be HTML5-conform, but in my opinion more elegant.
