Is linking to CSS or JavaScript without the protocol supported in all browsers?

Can I change all my links to just //?




I've learnt that I can reference CSS and JavaScript by using the "//domain/path" format rather than being specific about whether the resource should be loaded over HTTP or HTTPS. Examples: 





<link href="//ajax.googleapis.com/ajax/libs/jqueryui/1/themes/base/jquery-ui.css" rel="stylesheet" type="text/css" />

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>


The browser then loads the resources using the same protocol (schema) as the current page.



Is this supported in all browsers, and if not, which browsers don't support it?

    Yes, but IE 6-7 will download stylesheets twice with this method. Apart from that it works in all common browsers. See Can I change all my http:// links to just //?, Paul Irish - The protocol relative URL.

    According to this article.


    When used on a or @import for a stylesheet, IE7 and IE8
    download the file twice. All other uses, however, are just fine.


    And about IE 6


    The reason this doesn't work in IE6 is that the server is using SNI to
    deduce what certificate to return. XP (and thus IE6) doesn't support
    SNI in the HTTPS stack.

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.
