Jquery - Check: If scrollbar visible (div with overflow:auto)

By User



is it possible to check the overflow:auto from a div?


for example





HTML







<div id="my_div" style="width: 100px; height:100px; overflow:auto;" class="my_class"> 

  * content

</div>







JQUERY







$('.my_class').live('hover', function (event)

{

    if (event.type == 'mouseenter')

    {

         if( ...  if scrollbar visible ? ... )

         {

            alert('true'):

         }

         else

         {

            alert('false'):

         }

    }



});







  • Sometimes is the content short (no scrollbar) and sometimes long (scrollbar visible).







Thanks in advance!


Peter

    You need element.scrollHeight. Compare it with $(element).height().

    I should change a little thing of what Reigel said:

    (function($) {
    $.fn.hasScrollBar = function() {
    return this.get(0).scrollHeight > this.innerHeight();
    }
    })(jQuery);


    innerHeight counts control's height and it's top and bottom paddings

    Maybe a more simple solution.

    if ($(document).height() > $(window).height()) {
    // scrollbar
    }

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.
