Javascript エラーが発生します: オブジェクト # にはメソッド 'getElementById' がありません。選択した要素を HTML の別の選択ボックスに転送するボタンを作成しようとしています。どこでも見ましたが、nobodysソリューションは私にとってはうまくいくようです=\
Javascript
<script language="javascript">
function addDivision()
{
var selected = document.frmSubmit.getElementById("selectedDivisions");
var div = document.frmSubmit.getElementById("divisions");
var divId = div.options[div.selectedIndex].value;
var divText = div.options[div.selectedIndex].text;
var newOption = document.frmSubmit.createElement(divId);
newOption.text = divText;
selected.add(newOption,null);
}
