javascript - Get word under mouse pointer -


according (get word under cursor using javascript )link can word under mouse pointer.it's fine english language. change (for arabic language)

<p>سلام به همه</p> word: <span id="word"></span> <script type="text/javascript"> $(function() { // wrap words in spans $('p').each(function() { var $this = $(this); $this.html($this.text().replace(/[^\x00-\x80]+/g, "<span>$1</span>")); }); // bind each span $('p span').hover( function() { $('#word').text($(this).css('background-color','#ffff66').text()); }, function() { $('#word').text(''); $(this).css('background-color',''); } ); });

but return '$1' each word. please help!

you need parentheses appear in original regular expression. in regular expression notation, parentheses form "match group" substituted in "$1" in replace string.

$this.html($this.text().replace(/([^\x00-\x80]+)/g, "<span>$1</span>"));

without match groups in regex, $1 treated literal dollar sign , one.

when have multiple parenthesized match groups, groups used in replace dollar-sign-denoted numbered placeholders in order match groups opened (the first match group replaces $1, second replaces $2, etc).

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
