onchange - if else on javascript with the value of a select box (pure javascript) -


i'm working on select box have images instead of text, (on background css).

<script type="text/javascript"> function onchange(element) { element.style.backgroundcolor = "yellow"; element.classname = "on_change"; } </script> <select onchange="onchange(this);"> <option value="1" style="background: url(/one.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="2" style="background: url(/two.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="3" style="background: url(/three.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> </select>

the problem how value of selected option , if 1 set 1 image , if 2 set image background using pure javascript (no jquery)?

i know selectedindex key problem, i'm clueless of how use or how use on if else statement.

the script above 1 of trials, use script above perform same task.

<select onchange="this.style.backgroundcolor=this.options[this.selectedindex].style.backgroundcolor; this.style.color=this.options[this.selectedindex].style.color">

here working example. http://codebins.com/codes/home/4ldqpb9

you dont need if else change background image based on selectedindex.

function onchange(obj) { obj.style.backgroundimage = obj.options[obj.selectedindex].style.backgroundimage }

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
