変数コード= 'nl'を定義すると、以下のコードスニペットが機能しますが、この変数をドロップダウンリスト（var code = 'nl';のみ）から取ると、alert（code）;まったく同じ答えを与える。なぜ変数が私のために働いていないのですか？
どのようなヘルプも大歓迎です！
function putvariable() {
var e = document.getElementById("countrylist"); // select element
var strUser = e.options[e.selectedIndex].value;
var code = String(strUser);
var code = 'nl';
alert(code);
$.countrycodeuse = code;
return $.countrycodeuse
}
UPDATE＃1
私は;, VARコードは=「NL」取り出したときに変数「コード」の警告ボックスに同じに見えるので、私は、ドロップダウンリストから値を取得しません。だから私はvar code = 'nl'をコメントするときにアラートで同じ値を得る。ただし、この変数を使用する関数はcode = 'nl'のときは機能しません。コメントされています（したがって、ドロップダウンから変数を使用します）。
UPDATE＃2
全体のコードは少しくらいですが、多分それは役立ちます：
