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个步骤，现在如何可以使用空输入进入下一步。由于机器人等存在相当大的问题，验证表单上每个步骤的最佳方法是什么？
这是片段:
$(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();
} .wizard {

停止机器人的一种简单但有效的方法称为蜜 jar 。要实现这一点，您可以在表单末尾添加一个额外的输入并将其隐藏在 css 中。使用 PHP(建议用于表单验证!)您可以检查该字段是否为空。如果它不为空，那么您就知道机器人已经将数据输入到输入中，因为机器人会尝试通过填写所有字段来避免任何验证。JavaScript 或 jQuery 中的验证更多的是一种功能，而不是必须使用的功能用户在浏览器中将其关闭。
关于javascript - 向导表单验证，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42555718/
