问题
It's 2017 and it's the age of HTML5! In HTML5, the line break is <br>, NOT <br />. But for the life of it, I can't get CKeditor to ditch <br /> in favor of <br>.
The incorrect <br />'s are giving me all sorts of problems. Among them:
- Failed code validation
(In Firefox) Using JavaScript's innerHTML on a code block that was created with
<br />'s, returns<br>'s instead - which messes up comparisons about changes.
I found this old forum entry about the issue (in a related program, not in CKeditor itself):
http://ckeditor.com/forums/Support/are-not-validated-W3C-validator-How-change
But the suggested fix (changing config.docType in the config file) does NOT WORK!
I tried a bunch of different docTypes's, in both the top-level config.js and in core/config.js .
In top-level config.js , I tried:
config.docType = '<!DOCTYPE html>';
In core/config.js, I tried:
docType: '<!DOCTYPE html>',
But nothing works! :(
I also tried to hunt down instances of <br /> in the multitudes of files, but didn't find any in the core part of CKeditor. I presume that the <br /> string gets created dynamically??
How can I get CKeditor to spit out <br> rather than <br /> ?
Thanks!

Yay, it took some hardcore Googling (hard to phrase the search), but I found the answer! I hope this will help others.
Simply add:
CKEDITOR.on( 'instanceReady', function( ev ) {
// Output self-closing tags the HTML5 way, like <br>
ev.editor.dataProcessor.writer.selfClosingEnd = '>';
});
What it does, from what I understand, is to wait for the core plugin "HTML Output Writer" to be loaded - and when it is, it modifies the "writer", which is a property of each editor instance. The above way applies the change to all editors, but it could also be done to individual editor instances (though I find it hard to imagine why anyone would want to do the latter.)
For more info, from the CKEditor4 documentation: How Do I Output HTML Instead of XHTML Code Using CKEditor?
All right, CKEditor rocks! :D
