Question

大家好，你好吗？我正在研究项目，我有一个简单的问题：如何使用jQuery刷新页面后如何保持类切换？

无论何时按下按钮，它都可以正常工作，但是在重新加载页面时，它会恢复为切换前的状态。我如何解决此问题，对任何解决方案（最好是客户端）开放？（下面是我的按钮及其旁边的代码片段）

JS代码：

    $(document).on("click", "#toggle_the_div", function toggleDiv(e) {
        e.preventDefault();
        // Change Toggle Icon
        $('.icon_toggler').find('.ion').toggleClass('ion-md-radio-button-off ion-md-radio-button-on');
        if ($('.icon_toggler').find('.ion').hasClass('ion-md-radio-button-on')) {
            $($(this)).css("color", "var(--primary)");
        } else if ($('.icon_toggler').find('.ion').hasClass('ion-md-radio-button-off')) {
            $($(this)).css("color", "var(--dark)");
        }
        // Toggle Activation
        $('#hellodiv').toggleClass('is_toggled');
        if (localStorage.getItem('switch-state') && localStorage.getItem('switch-state') === "true") {
            //
        }
    });
