向导表单验证

Question

我有一个在bootstrap中制作的向导表单，我需要验证表单向导的每一步，现在如何使用空输入进入下一步。由于机器人等存在很多问题，验证表单上每一步的最佳方法是什么？

以下是摘录：

$(document).ready(function () {
        //Initialize tooltips
        $('.nav-tabs > li a[title]').tooltip();
        
        //Wizard
        $('a[data-toggle="tab"]').on('show.bs.tab', function (e) {
    
            var $target = $(e.target);
        
            if ($target.parent().hasClass('disabled')) {
                return false;
            }
        });
    
        $(".next-step").click(function (e) {
    
            var $active = $('.wizard .nav-tabs li.active');
            $active.next().removeClass('disabled');
            nextTab($active);
    
        });
        $(".prev-step").click(function (e) {
    
            var $active = $('.wizard .nav-tabs li.active');
            prevTab($active);
    
        });
    });
    
    function nextTab(elem) {
        $(elem).next().find('a[data-toggle="tab"]').click();
    }
    function prevTab(elem) {
        $(elem).prev().find('a[data-toggle="tab"]').click();
    }

Answer 1

一种简单但有效的停止僵尸程序的方法称为蜂蜜垃圾邮件。要实现此功能，您可以在表单末尾添加额外的输入并将其隐藏在css中。使用PHP（建议进行表单验证！），您可以检查该字段是否为空。如果它不是空的，那么你就知道机器人已经将数据输入到输入中，因为机器人将通过填写所有字段来尝试避免任何验证。在JavaScript或jQuery中的验证更多的是一个功能而不是必须使用，因为它可以是用户在浏览器中关闭了。
