使用Django提交表单后,如何留在网页上的同一标签上?

标签: django django-templates

当我刷新页面/为我的Django应用提交表单时,它总是转到第一个选项卡,而不是重定向到用户当前所在的选项卡。有没有简单的解决方法,因为我没有在线找到答案

您可以将标签选择保存到sessionStorage,并在页面加载时使用它。如果您使用Bootstrap(和jQuery)并遵循其basic guidelines,则应使用如下代码来完成这项工作:

// Save last active tab to sessionStorage
$('a[data-toggle="tab"]').on('shown.bs.tab', function () {
    try {
        sessionStorage.setItem('lastTab', $(this).attr('href'));
    } catch (error) {
        console.log(error);
    }
});

...,这将转到页面加载时的最后一个活动标签:

// Get last active tab from sesssionStorage and go there
var lastTab = sessionStorage.getItem('lastTab');
if (lastTab) {
    $('[href="' + lastTab + '"]').tab('show');
}

使用此代码时应注意的一件事是,您使用唯一的标签ID。

将此内容包含在Django模板中,您可以在其中使用以下导航选项卡:

    $(document).ready( function() {

        // Save last active tab to sessionStorage
        $('a[data-toggle="tab"]').on('shown.bs.tab', function () {
            try {
                sessionStorage.setItem('lastTab', $(this).attr('href'));
            } catch (error) {
                console.log(error);
            }
        });

        // Get last active tab from sesssionStorage and go there
        var lastTab = sessionStorage.getItem('lastTab');
        if (lastTab) {
            $('[href="' + lastTab + '"]').tab('show');
        }

    )};

</script>
