Validation: attribute 'data-dojo-type' is not a valid attribute of element 'button'

ShaningYu · ‎01-03-2014

Got several warnings on <button ... > <div ... >, etc., such as:
attribute 'data-dojo-type' is not a valid attribute of element 'button'
attribute 'data-dojo-props' is not a valid attribute of element 'button'
attribute 'data-dojo-type' is not a valid attribute of element 'div'
attribute 'data-dojo-props' is not a valid attribute of element 'div'
How can those problems be handled? Thanks.

Great!

Those errors should go away when you change the doctype of your webpage to the HTML5 standard:

<!DOCTYPE html>

Referring the thread at http://forums.arcgis.com/threads/12911-Warnings-why, I did
<%--<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">--%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
Namely, change to 4.01. The warning messages were gone. Thanks.

I believe 'data-*' is a valid property on HTML5 elements.

Is your webpage in HTML5?

You posted while I was posting; my suspicion was correct 😃

Is there any reason you aren't using HTML5?

Ideally, I should use HTML5. I need investigate more. Thanks for you to remind me. I have turned he Q as not answered.

Changed to

<!DOCTYPE html>

still shows not a valid attribute.

Interesting! What browser and what specific version are you using?

Run in IE 8

Given that IE-8 scores a whopping 43 out of a possible 555 points on http://html5test.com/ maybe that's the problem right there?

Indeed.... I'm not sure those warnings will ever go away when viewing your web application in IE8.
