javascript - IE のみでフォームの結果が表示されない

Question

次の例のフォームを使用すると、IE を除くすべてのブラウザーで問題なく結果が得られます。

フォームは IE では正常に処理されているように見えますが (正常に送信されたと表示されます)、結果は送信されません。コード内のすべてのテーブルを（個別に）削除して、それが役立つかどうかを確認してみましたが、そうではありませんでした。Javascript についてはよくわかりませんが、この問題を解決しようとしています。何か案は？検証からの JavaScript ( summation_check_final.js) は次のとおりです。

function validate_input(value,string){
var error = 0;
var reg = /^[\s\d]*$/
if(!reg.test(value)){
        alert(string + ' has to be blank or a number');
        error = 1;
}
return error;
}
