Omit repeated values in mysql query so the json file has only one of each



This is the query part of my json.php which is the source file of my jquery ui autocomplete input







$term = trim(strip_tags($_GET['term']));//retrieve the search term that autocomplete sends



$qstring = "SELECT nombre as value FROM ingredientes WHERE nombre LIKE '%".$term."%'";

$result = mysql_query($qstring);//query the database for entries containing the term



while ($row = mysql_fetch_array($result,MYSQL_ASSOC))//loop through the retrieved values

{

$row['value']=htmlentities(stripslashes($row['value']));

//$row['id']=(int)$row['id'];

$row_set[] = $row;//build an array

}

echo json_encode($row_set);//format the array into json data







The problem is that file my return result as:







[{"value":"one"},{"value":"one"},{"value":"ones"},{"value":"ona"}]







So the word will be suggested twice. How can I prevent that?

  1. $qstring = "SELECT DISTINCT nombre as value
    FROM ingredientes
    WHERE nombre LIKE '%".$term."%'";


    Or

    $qstring = "SELECT nombre as value
    FROM ingredientes
    WHERE nombre LIKE '%".$term."%'
    GROUP BY nombre";


    Do use mysql_real_escape_string though...

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

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()...
