我要验证步骤6。用户必须先填写当前步骤才能进行下一步。这意味着当用户在没有填写出生日期的情况下继续单击时，将出现警告，例如“此字段必填”。
当我尝试验证但不起作用时。无需验证当前步骤，用户即可轻松进行下一步。

这是我关于下一步和上一步以及进度条工作代码的查询。
$('.next').click(function () {
var pgrbar = $('.progress-bar').width();
var nextStep = $(this).data('step');
var currentStep = nextStep - 1;
var pgrbar = nextStep * 5.56;
$('.progress-bar').width(pgrbar + '%');
$('#step-' + currentStep).hide();
$('#step-' + nextStep).show();
$('#step-' + nextStep).removeClass("slideInLeft").addClass("slideInRight");
});
$('.prev').click(function () {
var pgrbar = $('.progress-bar').width();
var prevStep = $(this).data('step');
var currentStep = prevStep + 1;
var pgrbar = prevStep * 5.56;
$('.progress-bar').width(pgrbar + '%');
$('#step-' + currentStep).hide();
$('#step-' + prevStep).show();
$('#step-' + prevStep).removeClass("slideInRight").addClass("slideInLeft");
});
制作一个我们将用来验证该特定步骤的函数，我得到了validateStep(currentStep)。 currentStep包含当前步骤的索引或编号。
由于已经为步骤分配了特定的ID，因此我们将通过var targetStep = "#step-" + currentStep;访问当前步骤。
然后从它们中我们将.find()所有输入并检查是否存在空值或空值。 如果有一个空值，则发出警报并返回false，它将不会继续进行下一步。
使用下面的脚本；
$(document).ready(function() {
function validateStep(currentStep) {
var validate = true;
var targetStep = "#step-" + currentStep;
$(targetStep).find("input").each(function() {
if ($(this).val().length == 0 || $(this).val() == null) {
alert($(this).attr("name") + " is required.");
validate = false;
}
})
return validate;
}
$('.next').click(function() {
var pgrbar = $('.progress-bar').width();
var nextStep = $(this).data('step');
var currentStep = nextStep - 1;
var pgrbar = nextStep * 5.56;
$('.progress-bar').width(pgrbar + '%');
if (validateStep(currentStep)) {
$('#step-' + currentStep).hide();
$('#step-' + nextStep).show();
$('#step-' + nextStep).removeClass("slideInLeft").addClass("slideInRight");
}
});
$('.prev').click(function() {
var pgrbar = $('.progress-bar').width();
var prevStep = $(this).data('step');
var currentStep = prevStep + 1;
var pgrbar = prevStep * 5.56;
$('.progress-bar').width(pgrbar + '%');
$('#step-' + currentStep).hide();
$('#step-' + prevStep).show();
$('#step-' + prevStep).removeClass("slideInRight").addClass("slideInLeft");
});
});
