javascript - Remove element/s from an array -

how can remove item/s array in javascript ?

function restructurechatboxes() {     align = 0;     (x in chatboxes) {         chatboxtitle = chatboxes[x];          if ($("#chatbox_"+chatboxtitle).css('display') != 'none') {             if (align == 0) {                 $("#chatbox_"+chatboxtitle).css('right', '20px');             } else {                 width = (align)*(225+7)+20;                 $("#chatbox_"+chatboxtitle).css('right', width+'px');             }             align++;         }     } } 

and want remove chatbox when closed list.

function closechatbox(chatboxtitle) { //here remove list ?      $('#chatbox_'+chatboxtitle).css('display','none');     restructurechatboxes();      $.post("chat.php?action=closechat", { chatbox: chatboxtitle} , function(data){       });  } 

thanks answers.

first, find index of element want remove:

var array = [2, 5, 9]; var index = array.indexof(5); 

note: browser support indexof limited, not supported in ie7-8.

then remove splice:

if (index > -1) {     array.splice(index, 1); } 

the second parameter of splice number of elements remove. note, splice modifies array in place , returns new array containing elements have been removed.
