Examples: "90%", "250px" // intRows - 1 for ComboBox Mode, 3 or more for ListBox Mode // strAlign - The alignment of the TABLE containing the control. (The control is embedded in a TABLE.) // boolShowEditButtons - If this is true, the Add, Edit, and Delete buttons will be displayed. // boolShowSortButtons - If this is true, the Sort-Up, Sort-Down, and Alphabetize buttons will be displayed. // // Methods: // addOption(strValue, strText, boolIsSelected) - Add's an option to the option list. // sort() - Sorts the options in the control. // setButtonSort(strText) - Sorts the options in the control. // setButtonSortUp(strText) - Sorts the options in the control. // setButtonSortDown(strText) - Sorts the options in the control. // setButtonAdd(strText) - Sorts the options in the control. // setButtonEdit(strText) - Sorts the options in the control. // setButtonDelete(strText) - Sorts the options in the control. // // Properties: // deleteMessage - The message that pops up in a confirm box when you delete. // defaultOptionValue - The default value of an Option when you add it. // defaultOptionText - The default text of an Option when you add it. // sortKeyCode - The key code used to sort all Options alphabetically. // sortUpKeyCode - The key code used to sort the selected Option up. // sortDownKeyCode - The key code used to sort the selected Option down. // addKeyCode - The key code used to add an Option. // editKeyCode - The key code used to edit an Option. // deleteKeyCode - The key code used to delete an Option. // // Example 1: // var objEditable = new editableSelectBox("locationId", "cssGreenControls", "300px", 4, "left", true, false); // objEditable.setButtonAdd("Add City"); // objEditable.setButtonEdit("Modify City"); // objEditable.setButtonDelete("Remove City"); // objEditable.addOption(1, "Indianapolis, IN"); // objEditable.addOption(2, "Memphis, TN"); // objEditable.addOption(3, "New York, NY"); // objEditable.sort(); // // Example 2: // var objEditable = new editableSelectBox("locationId", null, "90%", 1, null, false, false); // objEditable.addOption(1, "Indianapolis, IN"); // objEditable.addOption(2, "Memphis, TN"); // objEditable.addOption(3, "New York, NY"); // //================================================================ var collection__EditableSelect = new Array(); function editableSelectBox(strID, strClass, strWidth, intRows, strAlign, boolShowEditButtons, boolShowSortButtons) { // Private properties and methods this.c_id = strID; this.c_class = (strClass == "" ? null : strClass); this.c_width = ((strWidth == "" || strWidth == null) ?
