我需要在预订表单(3 个标签)中创建标签，其中包含供用户填写然后提交的文本框。我似乎无法让它工作，但我不确定为什么？我是否将内容(文本框)放在了错误的位置？
$(document).ready(function() {
//tabs function
$("#reservation_tabs").tabs();
var emailPattern = /\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}\b/;
// add a span element after each text box
$(":text").after("<span class='error'>*</span>");
// move the focus to the first text box
$("#arrival_date").focus();
// the handler for the submit event of the form
// executed when the submit button is clicked
$("#reservation_form").submit(
function(event) {
var isValid = true;
// validate the requested arrival date
if ($("#arrival_date").val() == "") {
$("#arrival_date").next().text("This field is required.");
isValid = false;
} else {
$("#arrival_date").next().text("");
}
// validate the number of nights
if ($("#nights").val() == "") {
$("#nights").next().text("This field is required.");
isValid = false;
} else if (isNaN($("#nights").val())) {
$("#nights").next().text("This field must be numeric.");
isValid = false;
} else {
$("#nights").next().text("");
}
// validate the name entry
var name = $("#name").val().trim();
if (name == "") {
$("#name").next().text("This field is required.");
isValid = false;
}
else {
$("#name").val(name);
$("#name").next().text("");
}
// validate the email entry with a regular expression
var email = $("#email").val();
if (email == "") {
$("#email").next().text("This field is required.");
isValid = false;
} else if ( !emailPattern.test(email) ) {
$("#email").next().text("Must be a valid email address.");
isValid = false;
} else {
$("#email").next().text("");
}
// validate the phone number
if ($("#phone").val() == "") {
$("#phone").next().text("This field is required.");
isValid = false;
} else {
$("#phone").next().text("");
}
// prevent the submission of the form if any entries are invalid
if (isValid == false) {
event.preventDefault();
}
} // end function
); // end submit
}); // end readybody {

<p>Notification of cancellation or arrival date change must be
received more than three days (72 hours) prior to the confirmed arrival date for the
reservation deposit to be refundable. Email notification is acceptable, and a cancellation
confirmation will be sent to you. Failure to check-in on the scheduled arrival date
will result in the cancellation of the reservation including any remaining nights,
and the reservation deposit shall be forfeited.</p>

选项卡是 jQuery UI 的一部分 https://jqueryui.com/tabs/ lib(它与 jQuery 本身是不同的文件，所以你需要它们)你没有引用。 (cdns here )
关于javascript - 选项卡在 jQuery 中不起作用？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43674297/
