</html>如何使用选定的jquery在单击保存按钮后将选定的选项保存在同一位置，即使我正在刷新页面，选定的选项也应该保持在同一地方。
将所选选项存储到localStorage中，并在页面加载时检索它。
https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage
if(!!localStorage.getItem("selected")) {
$("#rememberSelected").val(localStorage.getItem("selected").split(",")).trigger("chosen:updated");
}
$("button").on("click", function() {
localStorage.setItem("selected", $("#rememberSelected").val());
});
您可以将状态保存到localStorage
<script>
if (localStorage['select-state']) {
$( "select" ).val(JSON.parse(localStorage['select-state']));
}
$( "select" ).change(function() {
localStorage['select-state'] = JSON.stringify($(this).val());
});
</script>
