Hi, I have the following php-script, now I need to do the same thing in javascript. Is there a funcion in javascript that works similar to the php function, I have been searching for days but cannot find anything similar? What I want to do is to count the number of times a certain word is beeing used in an array.

$interfaceA = array($interfaceA_1,$interfaceA_2,$interfaceA_3,$interfaceA_4,$interfaceA_5,$interfaceA_6,$interfaceA_7,$interfaceA_8);       

$interfaceA_array=array_count_values($interfaceA);
$knappsatsA = $interfaceA_array[gui_knappsats];
$touchpanelA = $interfaceA_array[gui_touchpanel];

Many thanks linda
