What javascript event gets fired when ios safari gets called from another app

By User



I'm working on a mobile website / iPhone app combination. Upon entering the mobile website, I prompt the user to 'go to the app', 'download the app', or 'use mobile website'.





From various entry points to the mobile website, I'm mostly worried about verification emails and text messages, so the user will check email, follow the verification link, enter Safari, get prompted to 'go to the app' and the verification link is sent to the app for it to handle.





Now in the same session, if the user gets another email regarding the app, the user will check email again, follow a different verification link to Safari, and I want the 'go to the app' to work the same with the new link.





Some quirks are that upon entering the mobile website, the verification link is stored and the URL is switched to site.com/home. The iphone overlay is completely separate from the rest of the site and doesn't have access to the site's storage of the verification link so the event needs to fire as soon as the site loads. This works when first loading the page, but upon re-entering the second time, I need to listen to event that triggers as soon as ios Safari re-enters. I've tried listening to "pageshow" but by that time, the URL is already site.com/home.





Thanks

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.
