TYPO3 Core

related to #16641

This issue still exists in TYPO3 4.5. In sysext\cms\tslib\class.tslib_content.php, lines 1498 - 1502, it is not possible to insert something like "scrollbars=yes" via TypoScript. The parameters are hardcoded.

Actually, you can add parameters to the popup using typoscript, with JSwindow_params

See documentation here:

https://docs.typo3.org/typo3cms/TyposcriptReference/Functions/Typolink/Index.html#jswindow-params

example:

page=PAGE
page.60=TEXT
page.60.value=hello world
page.60.typolink.parameter = 507 400x300
page.60.typolink.JSwindow_params=scrollbars=1,resizable=0,toolbar=0,status=0
page.60.wrap=<p>|</p>

The only "hardcoded" parameter seems to be the name "FEopenLink" - see #31636.

By the way

Modern browsers like Chrome or Firefox ignore the parameter resizable=0 ;)

I'm not 100% sure but I think the TypoScript settings for JSwindow_params don't apply to the click enlarge context. In TYPO3 v8.7 the source code in method imageLinkWrap of class \TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer (lines 1468 - 1478) is basically the same as it was in TYPO3 v4.5:

$onClick = 'openPic('
    . GeneralUtility::quoteJSvalue($this->getTypoScriptFrontendController()->baseUrlWrap($url)) . ','
    . '\'' . ($newWindow ? md5($url) : 'thePicture') . '\','
    . GeneralUtility::quoteJSvalue('width=' . ($processedFile->getProperty('width') + $offset[0])
    . ',height=' . ($processedFile->getProperty('height') + $offset[1]) . ',status=0,menubar=0')
    . '); return false;';
$a1 = '<a href="' . htmlspecialchars($url) . '"'
    . ' onclick="' . htmlspecialchars($onClick) . '"'
    . ($target !== '' ? ' target="' . htmlspecialchars($target) . '"' : '')
    . $this->getTypoScriptFrontendController()->ATagParams . '>';
$a2 = '</a>';

Some attributes and values are hard coded. Adding custom attributes is not possible.

@Tobias Schmidt good point. Thank you for your findings
