Implementing Tabs tab custom plug-in based on jQuery

No matter how many controls I found online, the functions were not satisfactory, so I had to write it myself.

Many people need to use the Tabs plug-in, and there are many examples on the Internet, but either the style does not match or the use is not used (my own writing may not be better than others, but I love it when I use it smoothly)

I will post it directly below Code, don’t comment if you don’t like it:

(function ($) {
 'use strict';
 var defaults = {
 type: "iframe",
 onchanged: null,
 style: {
  header_panel: "tab-headers",
  content_panel: "tab-contents",
  header: "tab-header",
  content: "tab-content",
  selected: "selected",
  icon_base: "fa",
  icon_close: "fa-close"
 }
 }
 var methods = {
 init: function (options) {
  return this.each(function () {
  var $this = $(this);
  if (!$this.hasClass("tw.tabs")) {
   $this.addClass("tabs");
  }
  var settings = $this.data('tw.tabs');
  if (typeof (settings) == 'undefined') {
   settings = $.extend({}, defaults, options);
   $this.data('tw.tabs', settings);
  } else {
   settings = $.extend({}, settings, options);
   $this.data('tw.tabs', settings);
  }
  $this.empty();
  $this.append($("<ul class=&#39;" + settings.style.header_panel + "&#39;></ul>"));
  $this.append($("<div class=&#39;" + settings.style.content_panel + "&#39;></div>"));
  if (settings.data) {
   if (typeof settings.data === &#39;string&#39;) {
   settings.data = $.parseJSON(settings.data);
   }
   $.each(settings.data, function () {
   $this.tabs("add", this);
   });
  }
  });
 },
 add: function (tab) {
  var $this = $(this);
  var settings = $this.data("tw.tabs");
  var headers = $this.find("." + settings.style.header_panel);
  var contents = $this.find("." + settings.style.content_panel);
  if (headers.find("[data-tab=&#39;" + tab.id + "&#39;]").length == 0) {
  var header = $("<li class=&#39;" + settings.style.header + "&#39; data-tab=&#39;" + tab.id + "&#39;>" +
   "<i class=&#39;" + settings.style.icon_base + "" + tab.icon + "&#39;></i>" +
   "<span class=&#39;tab-title&#39;>" + tab.name + "</span></li>");
  if (tab.canClose) {
   var close = $("<i class=&#39;" + settings.style.icon_base + "" + settings.style.icon_close + "&#39;></i>");
   close.click(function () {
   $this.tabs("remove", tab.id);
   });
   header.append(close);
  }
  header.data("tw.tab", tab);
  header.click(function () {
   $this.tabs("select", tab);
  });
  headers.append(header);
  var content = $("<div class=&#39;" + settings.style.content + "&#39; data-tab=&#39;" + tab.id + "&#39;></div>");
  if (settings.type == "iframe") {
   content.append("<iframe src=&#39;" + tab.url + "?target_id=" + tab.id + "&#39;></iframe>");
  } else if (settings.type == "ajax"){
   $.ajax({
   url: tab.url,
