In my Grails GSP file I'm using the HTML meta tag:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
The problem is that Grails closes this tag and renders it as:
<meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
This fails W3C's HTML validation (since my doctype is HTML and not XHTML). Is there a fix for this? How can I get Grails to not interpret the meta tag?
I'm using grails-1.2-M4.
Follow up: I create the Grails bug GRAILS-5696 for this issue.
Not sure that this is the most beautiful solution, but at least it will work for your case:
<%= '<meta http-equiv="Content-Type" content="text/html; charset=utf-8">' %>
Well...this does not work since it is preprocessed by Grails before displayed as is.
So the only solution I see is to create a TagLib and output the content like this:
class MetaTagLib {
static namespace = 'my'
def meta = {
out << "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/>"
}
}
and use it like:
<my:meta />
It works. Tested.
You could validate as HTML5 instead of HTML 4.01, by using <!DOCTYPE html> (that's it, really!). HTML5 allows trailing slashes even in the HTML syntax, in order to allow for systems like this that produce pseudo-XHTML.
Of course, HTML5 is not yet a finished standard; it may change. I think that this aspect of it is unlikely to be changed, but there is still some fairly contentious debate about a lot of the new HTML5 features, so keep in mind that it's not yet finalized.
