我有以下重定向到确认页面的表单，当浏览器中禁用javascript时，我希望保持这种行为，但当启用javascript时，我们希望使用弹出窗口进行确认。当启用javascript只显示确认弹出窗口时，我如何禁用表单操作？ps：我必须使用jquery ui轻量级插件，这就是为什么我不使用引导模式的原因。

$("#btn_trash").click(function() {

$('#confirmDialog').dialog({

width: 500,

Oui: function() {
ret = "yes";
$(this).dialog("close");

<form id="delete_board_form" action='board/submit_delete' method='post'>
<input type='text' name='delete' value='<?= $board->id ?>' hidden>
<button id="btn_trash" class="btn" type="Submit">

对我有用的是使用event.prventDefault((
<form id="delete_board_form" action='board/submit_delete' method='post' onsubmit="event.preventDefault()">
<input type='text' name='delete' value='<?= $board->id ?>' hidden>
<button id="btn_trash" class="btn" type="Submit">
<svg class="bi text-white" width="20" height="20">
<use xlink:href="assets/ressources/bootstrap-icons/bootstrap-icons.svg#trash" />
</svg>
</button>
</form>
<div id="content"></div>
<div id="confirmDialog" title="Attention" hidden>
<p>Confirmez-vous le lancement de cette opération irréversible ?</p>
</div>
