Breaking: #88772 - JavaScript script tags omit type=text/javascript in HTML5
See forge#88772
Description
When rendering HTML5 output, <script>
tags do not the additional attribute type=text/
anymore as it is considered optional, and if none given, modern browsers fall back to this type
already.
See the official W3C definition here: https://www.w3.org/TR/html52/semantics-scripting.html#element-attrdef-script-type
For this reason, all of TYPO3's Backend (which is rendering HTML5) and Installer do not include
this optional attribute in <script>
tags anymore.
For TYPO3 Frontend rendering, the attribute is omitted when having no doctype or HTML5 as doctype
configured (via TypoScript config.
). This leads to a minimal smaller
HTML document submitted to the client.
For any XHTML or HTML4-based website, the attribute is still added.
Impact
TYPO3's Frontend rendering does not render type=text/
anymore in <script>
tags when
rendering a HTML5 output, unless explicitly specified.
Affected Installations
Any TYPO3 installation running a HTML5-based frontend output.
Migration
As all modern browsers do not need this tag, and the specification says it's optional, there is no migration needed at all.
If still requested by a specific project, it can be added via:
page.includeJS.myfile = EXT:site_mysite/Resources/Public/JavaScript/myfile.js
page.includeJS.myfile.type = text/javascript
