html - Change :hover CSS properties with JavaScript -


i need find way change css :hover properties using javascript.

for example, suppose have html code:

<table> <tr> <td>hover 1</td> <td>hover 2</td> </tr> </table>

and following css code:

table td:hover { background:#ff0000; }

i use javascript change <td> hover properties to, say, background:#00ff00. know access style background property using javascript as:

document.getelementsbytagname("td").style.background="#00ff00";

but don't know of javascript equivalent :hover. how change these <td>'s :hover background using javascript?

your appreciated!

pseudo classes :hover never refer element, element satisfies conditions of stylesheet rule. need edit stylesheet rule, append new rule, or add new stylesheet includes new :hover rule.

var css = 'table td:hover{ background-color: #00ff00 }'; var style = document.createelement('style'); if (style.stylesheet) { style.stylesheet.csstext = css; } else { style.appendchild(document.createtextnode(css)); } document.getelementsbytagname('head')[0].appendchild(style);

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
