jquery selector to count the number of visible table rows?

Image
By User


I've got this html: 





<table>

    <tr style="display:table-row"><td>blah</td></tr>

    <tr style="display:none"><td>blah</td></tr>

    <tr style="display:none"><td>blah</td></tr>

    <tr style="display:table-row"><td>blah</td></tr>

    <tr style="display:table-row"><td>blah</td></tr>

</table>


I need to count the number of rows that don't have display:none . How can I do that?

    You can use the :visible selector and .length like this:

    var numOfVisibleRows = $('tr:visible').length;


    If the <table> itself isn't visible on the screen (:visible returns false if any parent is hidden, the element doesn't have to be hidden directly), then use .filter(), like this:

    var numOfVisibleRows = $('tr').filter(function() {
    return $(this).css('display') !== 'none';
    }).length;

    $('tr:visible').length

    $("tr:visible") gets you the results of the visible rows, and I think you can then do .length

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.
