Warnings of valid HTML5 attributes in Eclipse -

-

i use eclipse , write jsp files html5 content. have example line:

<div class="test" data-role="test123">

in eclipse warning:

undefined attribute name (data-role)

what needed done these warnings won't appear anymore? in html5 attribute allowed (data-*) can see here: http://ejohn.org/blog/html-5-data-attributes/

best regards.

it seems eclipse still has problems validating html5 elements , attributes now.

i'm running mars 4.5.1 , have had warnings <main> element, despite fact there no warnings <section> element.

but there solution!

window > preferences > web > html files > validation

window > preferences > web > html files > validation

here can tick ignore specified element names in validation checkbox , enter names of elements eclipse incorrectly warning about.

in case, want tick ignore specified attribute names in validation checkbox , enter data-role attribute.

after click 'apply', eclipse ask full validation of project. select 'yes' , changes take effect.

no more squiggly yellow lines yay! :d
