Description

When using the preview mode in TYPO3 frontend most of Javascript wont work in Internet Explorer 7 because of the hook "hook_feofe".

The entire content of workspaces/Resources/Private/Templates/Preview/Preview.html is interpreted and inserted at the beginning of the PHP and so kills the HTML integrity.

A way of fixing this is to set the following lines in the hook:

$workspaceVars = t3lib_div::_GP('tx_workspaces_web_workspacesworkspaces'); if(count($workspaceVars) == 0) { return; }

could you be a bit more precise? sure we add the whole template contents but what exactly is wrong in IE7 that this crashes?

Hi,

the IE7 crashes because the HTML in clearly invalid.

in tx_Workspaces_Service_Fehooks::hook_eofe there is the following:
echo $GLOBALS['TSFE']->cObj->cObjGetSingle( 'FLUIDTEMPLATE', array( 'file' => 'EXT:workspaces/Resources/Private/Templates/Preview/Preview.html', 'variables.' => array( 'backendDomain' => 'TEXT', 'backendDomain.' => array('value' => $GLOBALS['BE_USER']->getSessionData('workspaces.backend_domain')) ) ) );

This generates a huge amount of code that is just thrown in the php output.

The HTML Code will look like this:

<script type="text/javascript">

        // @todo redirect to split module if this is opened standalone

        // having this is very important, otherwise the parent.resize call will fail
    document.domain = 'domainXY';

    var asNumber = function(val) {
        return isNaN(val) ? 0 : parseInt(val, 10);
    };
    var TYPO3 = {};
    TYPO3.ready = function () {
        // make sure we're in the workspace preview module
        if (typeof parent.resize == 'function') {
                // try to find the height of the document
            var docHeight = Math.max(
                asNumber(window.innerHeight),
                asNumber(document.height),
                asNumber(document.body.scrollHeight),
                asNumber(document.body.offsetHeight),
                asNumber(document.body.clientHeight),
                asNumber(document.documentElement.scrollHeight),
                asNumber(document.documentElement.offsetHeight),
                asNumber(document.documentElement.clientHeight)
            );
            parent.resize(docHeight);
                // remove the ugly red box if we're in the ws-repview frames
            var element = document.getElementById('typo3-previewInfo');
            element.parentNode.removeChild(element);
        }
    };
        // trigger this after content is loaded, inspired by jQuery
    if (document.addEventListener && !/opera/.test(navigator.userAgent.toLowerCase())) {
        document.addEventListener("DOMContentLoaded", TYPO3.ready, false);
    } else {
        (function() {
            if (document.readyState != "loaded" && document.readyState != "complete") {
                setTimeout(arguments.callee, 10);
            } else {
                TYPO3.ready();
            }
        })();
    }
</script>

This makes Internet Explorer overreacte (like little girls do when you take theire toys away) and break the javascript code.

Another way to fix this could be:

$params['pObj']->content = str_replace('</body>', $GLOBALS['TSFE']->cObj->cObjGetSingle(
    'FLUIDTEMPLATE',
    array(
        'file' => 'EXT:workspaces/Resources/Private/Templates/Preview/Preview.html',
        'variables.' => array(
            'backendDomain' => 'TEXT',
            'backendDomain.' => array('value' => $GLOBALS['BE_USER']->getSessionData('workspaces.backend_domain'))
        )
    )
).'</body>',$params['pObj']->content);

I think that what really makes IE7 feel so bad is that he doesn't get why there is a HTML Tag after there has already been a script tag. Or worse, he just ignores the <script>-tags and this code gets never executed.
