制表符在 jQuery 中不起作用？

Question

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？我是不是把内容（文本框）放错地方了？

$(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 ready

制表符是 jQuery UI https://jqueryui.com/tabs/ lib (it's different file than the jQuery itself, so you need them both) which you haven't referenced. (cdns here)
