How to find out whether an element is in a hidden iframe

Image
By User



Using jQuery, one can easily find out whether a particular element is visible using







$(element).is(':visible')







While having some limitations (doesn't cover css visibility hidden or the actual visibility in the viewport, i.e. whether it's covered by other elements or scrolled away), I find it being useful for my scenario. The catch is, it only works within one iframe.





If the element has any parent within its document with display:none; , it returns false. If the whole document is included in an iframe which has display:none , it returns true. Is it possible to somehow detect this in another way ?

    Hmm, seems like you have to call top (parent) document within an iframe, then search for specific iframe and check if it's visible.

    You'll probably have to have same domain/subdomain for this to work, but anyway:

    Let's assume you know iframe id/class (you have to).

    if ($(top).find('#iframeID').is(':visible')) {
    // iframe is visible
    } else {
    // iframe is NOT visible
    }


    Can't guarantee correct work.

    Seems that the window's frameElement property works in all browsers and delivers the current iframe where the window is contained (if cross-domain restriction doesn't apply, which was my case).

    not possible afaik. an iframe is basically a different site and as such guarded against xss. simply don't use iframes but server-side includes.

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
