私は隠しボタンを表示しようとしています ボタンをクリックすると同時に動作しますが、同時にページも更新されます。何がリフレッシュを引き起こしているのか分かりません。そのaspx.csがさわやかな原因になっている場合hideとshow関数はページを更新し続けます
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#buttontest").click(function() {
$("#hello").toggle();
});
});</script>
<button id="buttontest">test</button>
<div id="hello">hello</div>
わからない:これは、ASPXである

私はまだすべてのこれらのに慣れていないんですが、任意のヘルプは
をいただければ幸いです編集:私はボタンとJavaScriptを編集した、それはまだリフレッシュを引き起こした
ボタンのタイプ属性は「送信」になります。それを「ボタン」に変更します。それはそれを動作させるかもしれない。 –
hideとshow機能は動作していますが、ボタンをクリックするたびにページが更新されます –
