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

ShaningYu — Fri, 03 Jan 2014 16:06:05 GMT

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.

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.

Great!

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

<!DOCTYPE html>

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.

The errors were gone from the files in VS 2010. Not sure why. Thanks to Jon for his valuable response.
