Q1308 How to you remove an element or item from an array (ie make it smaller)?

<script language="JavaScript"><!--
function RemoveElement(elementnr) {
    // elementnr is the number of the element you wish to remove
    // the name of the array used here is array

    for (elementnr<array.length,elementnr++) {
        // assigns the value of elementnr+1 to elementnr, so you move all items by 1
        array[elementnr] = array[elementnr + 1];
    }
    array.length=array.length-1;
    // Yes it is as easy as this!
}
//--></script>
