目前网上有很多各种各样的手风琴插件,但是没有一个完整实现了的侧菜单,今天写了一个可以无限子节点的手风琴侧菜单,有需要的可以参考一下,有什么好的想法可以留言。(没有经过彻底测试,不过问题应该不大)

下面老规矩,直接贴代码:

(function ($) {
 'use strict';
 var defaults = {
  url: null,
  param: {},
  data: {},
  fill: true,
  level_space: 15,
  onitemclick: null,
  style: {
   header: "accordion-header",
   header_title: "accordion-header-title",
   content: "accordion-content",
   selected: "selected",
   icon_base: "fa",
   icon_collapse: "fa-angle-up",
   icon_expand: "fa-angle-down"
  }
 }
 var methods = {
  init: function (options) {
   return this.each(function () {
    var $this = $(this);
    if (!$this.hasClass("accordion")) {
     $this.addClass("accordion");
    }
    var settings = $this.data('tw.accordion');
    if (typeof (settings) == 'undefined') {
     settings = $.extend({}, defaults, options);
     $this.data('tw.accordion', settings);
    } else {
     settings = $.extend({}, settings, options);
     $this.data('tw.accordion', settings);
    }
    if (settings.url) {
     $.ajax({
      type: "post",
      async: false,
      url: settings.url,
      data: settings.param,
      success: function (data) {
       settings.data = data;
      }
     });
    }
    if (settings.fill) {
     $this.height("100%");
    }
    if (settings.data.length > 0) {
     $this.data("count", settings.data.length);
     $.each(settings.data, function () {
      this.level = 1;
      var item = $this.accordion("add", this);
      $this.append(item);
     });
     if ($this.find("." + settings.style.selected).length == 0) {
      var data = $this.find(">li:first-child").data("data");
      $this.accordion("select", data);
     }
    }
   });
  },
  add: function (data) {
   var $this = $(this);
   var settings = $this.data("tw.accordion");
   var item = $("<li class='" + settings.style.header + "'></li>");
   item.data("data", data);
   var header = $("<div class='" + settings.style.header_title + "' data-accordion='" + data.id + "'>" +
    "<i class='" + settings.style.icon_base + "" + data.icon + "'></i>" +
    "<span>" + data.name + "</span></div>");
   header.css("padding-left", settings.level_space * data.level);
   item.append(header);
   if (data.childrens) {
    var toggle = $("<i class='" + settings.style.icon_base + "" + settings.style.icon_collapse + "'></i>");
    toggle.css({ "font-size": "1.4em", "position": "absolute", "top": "7px", "right": "7px" });
    header.append(toggle);
    var content = $("<ul class='" + settings.style.content + "'></ul>");
    content.data("count", data.childrens.length);

    sibling.removeClass(settings.style.selected).children("." + settings.style.selected).removeClass(settings.style.selected);
    sibling.children("." + settings.style.icon_expand).removeClass(settings.style.icon_expand).addClass(settings.style.icon_collapse);
