Adding and Removing Items from an Array

In this article we shall be covering one approach to adding and removing items from a JavaSCRIPT array.

function addItemToList() {
destList = window.document.menuList.addList; srcList = window.document.menuList.stockList;
    var len = destList.length;
    for(var i = 0; i < srcList.length; i++) {
        if ((srcList.options[i] != null) && (srcList.options[i].selected)) { var found = false;
            for(var count = 0; count < len; count++) {
                if (destList.options[count] != null) {
                    if (srcList.options[i].text == destList.options[count].text) {
                        found = true; break;
                    }
                }
             }
             if (found != true) {
                destList.options[len] = new Option(srcList.options[i].text);
                 len++;
              }
          }
       }
    }
