Remove element/s from an array

Question

How can I remove a item/s from an Array in JavaScript ?

function restructureChatBoxes() {
    align = 0;
    for (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 I want to remove the Chatbox when its closed from the List.

function closeChatBox(chatboxtitle) {
//HERE THE REMOVE FROM LIST ? 
    $('#chatbox_'+chatboxtitle).css('display','none');
    restructureChatBoxes();

    $.post("chat.php?action=closechat", { chatbox: chatboxtitle} , function(data){  
    });

}

Thanks for all Answers.

First, find the index of the element you want to remove:

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

Note: browser support for indexOf is limited, it is not supported in IE7-8.

Then remove it with splice:

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

The second parameter of splice is the number of elements to remove. Note, splice modifies the array in place and returns a new array containing the elements that have been removed.

You don't get the point. You sold another one's answer as yours. How would you call that? And no, you didn't mark the question as duplicate. What about that? – a better oliver Jul 11 '15 at 11:16
