我正在实现jquery-Step Advance Form。
在这里,如果年龄小于18岁,我需要跳过一步, 这是一个类似的例子,在上面的链接中工作, 当我尝试实现相同的功能时, 跳过一步很好,但一旦我需要在单击“上一页”按钮时返回,JS就会陷入无尽的循环中!! 这里我为此创建了jsfiddle。
以下是JS:
我注意到currentIndex和newIndex参数的值不正确,但我不明白为什么?

以下是JS:
$(function () {
$("#form-3").steps({
bodyTag: "fieldset",
headerTag: "h1",
onStepChanging: function (event, currentIndex, newIndex) {
if (currentIndex > newIndex) {
return true;
}
if (newIndex === 3 && Number($("#age").val()) < 18) {
return false;
}
var form = $(this);
if (currentIndex < newIndex) {
$("#form-3 .body:eq(" + newIndex + ") label.error", form).remove();
$("#form-3 .body:eq(" + newIndex + ") .error", form).removeClass("error");
}
return true;
},
onStepChanged: function (event, currentIndex, priorIndex) {
if (currentIndex === 2 && Number($("#age").val()) >= 18) {
$(this).steps("next");
}
if (currentIndex === 2 && priorIndex === 3) {
$(this).steps("previous");
}
},
onFinishing: function (event, currentIndex) {
return true;
},
onFinished: function (event, currentIndex) {
var form = $(this);
form.submit();
}
})
});
