Bootstrap Ace template worth sharing to achieve menu and tab page effects_javascript skills

This article shares the menu style and iframe-based Tab page effect using the Ace template in the project.

1. Effect display

After struggling for a long time, I finally extracted the menu style and Tab page effects from the project.

1. The effect of initial loading

2. Expand menu (supports multi-level expansion, code introduction below)

3. Click the submenu to open the corresponding page in the form of a Tab page

4. Support menu folding

5. When there are too many open menus, they will automatically wrap into new lines and display automatically after folding

2. Code examples
There are ready-made things that are very convenient to use. Generally speaking, the functions of the Bootstrap Ace template are relatively powerful and support various terminal devices. This article mainly uses the effect of its menu. Let’s take a look at the implementation code of the Ace template menu effect.

1. Menu effect
Since Ace is based on Bootstrap, you first need to reference the jquery and bootstrap components. Let's take a general look at which files it needs to reference. ​

<script src="/Scripts/jquery-1.9.1.min.js"></script>

  <script src="/Content/bootstrap/js/bootstrap.min.js"></script>
  <link href="/Content/bootstrap/css/bootstrap.min.css" rel="stylesheet" />

  <link href="/Content/font-awesome/css/font-awesome.min.css" rel="stylesheet" />
  <link href="/Content/ace/css/ace-rtl.min.css" rel="stylesheet" />
  <link href="/Content/ace/css/ace-skins.min.css" rel="stylesheet" />
  <link href="/Content/sidebar-menu/sidebar-menu.css" rel="stylesheet"/>

  <script src="/Content/ace/js/ace-extra.min.js"></script>
  <script src="/Content/ace/js/ace.min.js"></script>

　 <script src="/Content/sidebar-menu/sidebar-menu.js"></script>

Haha, it looks like there are quite a lot. Except for the last js file (887fa161fea4b0c927efde03e6925e732cacc6d41bbb37262a98f745aa00fbf0) which is encapsulated by the blogger himself, the others are basically the feature components required by the components. . Take a look at which html tags should be placed on the page:

　<div class="sidebar" id="sidebar">
        <ul class="nav nav-list" id="menu"></ul>
        <div class="sidebar-collapse" id="sidebar-collapse">
          <i class="icon-double-angle-left" data-icon1="icon-double-angle-left" data-icon2="icon-double-angle-right"></i>
        </div>
      </div>

Let’s take a look at the encapsulation method in the sidebar-menu.js file:

(function ($) {
  $.fn.sidebarMenu = function (options) {
    options = $.extend({}, $.fn.sidebarMenu.defaults, options || {});
    var target = $(this);
    target.addClass('nav');
    target.addClass('nav-list');
    if (options.data) {
      init(target, options.data);
    }
    else {
      if (!options.url) return;
      $.getJSON(options.url, options.param, function (data) {
        init(target, data);
      });
    }
    var url = window.location.pathname;
    //menu = target.find("[href='" + url + "']");
    //menu.parent().addClass('active');
    //menu.parent().parentsUntil('.nav-list', 'li').addClass('active').addClass('open');
    function init(target, data) {
      $.each(data, function (i, item) {
        var li = $('<li></li>');
        var a = $('<a></a>');
        var icon = $('<i></i>');
        //icon.addClass('glyphicon');
        icon.addClass(item.icon);
        var text = $('<span></span>');
        text.addClass('menu-text').text(item.text);
        a.append(icon);
        a.append(text);
        if (item.menus&&item.menus.length>0) {
          a.attr('href', '#');
          a.addClass('dropdown-toggle');
          var arrow = $('<b></b>');
          arrow.addClass('arrow').addClass('icon-angle-down');
          a.append(arrow);
          li.append(a);
          var menus = $('<ul></ul>');
          menus.addClass('submenu');
          init(menus, item.menus);
          li.append(menus);
        }
        else {
          var href = 'javascript:addTabs({id:\'' + item.id + '\',title: \'' + item.text + '\',close: true,url: \'' + item.url + '\'});';
          a.attr('href', href);
          //if (item.istab)
          //  a.attr('href', href);
          //else {
          //  a.attr('href', item.url);
          //  a.attr('title', item.text);
          //  a.attr('target', '_blank')
          //}
          li.append(a);
        }
        target.append(li);
      });
    }
  }

  $.fn.sidebarMenu.defaults = {
    url: null,
    param: null,
    data: null
  };
})(jQuery);

Call the sidebar-menu method directly on the page

$(function () {
      $('#menu').sidebarMenu({
        data: [{
          id: '1',
          text: '系统设置',
          icon: 'icon-cog',
          url: '',
          menus: [{
            id: '11',
            text: '编码管理',
            icon: 'icon-glass',
            url: '/CodeType/Index'
          }]
        }, {
          id: '2',
          text: '基础数据',
          icon: 'icon-leaf',
          url: '',
          menus: [{
            id: '21',
            text: '基础特征',
            icon: 'icon-glass',
            url: '/BasicData/BasicFeature/Index'
          }, {
            id: '22',
            text: '特征管理',
            icon: 'icon-glass',
            url: '/BasicData/Features/Index'
          }, {
            id: '23',
            text: '物料维护',
            icon: 'icon-glass',
            url: '/Model/Index'
          }, {
            id: '24',
            text: '站点管理',
            icon: 'icon-glass',
            url: '/Station/Index'
          }]
        }, {
          id: '3',
          text: '权限管理',
          icon: 'icon-user',
          url: '',
          menus: [{
            id: '31',
            text: '用户管理',
            icon: 'icon-user',
            url: '/SystemSetting/User'
          }, {
            id: '32',
            text: '角色管理',
            icon: 'icon-apple',
            url: '/SystemSetting/Role'
          }, {
            id: '33',
            text: '菜单管理',
            icon: 'icon-list',
            url: '/SystemSetting/Menu'
          }, {
            id: '34',
            text: '部门管理',
            icon: 'icon-glass',
            url: '/SystemSetting/Department'
          }]
        }, {
          id: '4',
          text: '订单管理',
          icon: 'icon-envelope',
          url: '',
          menus: [{
            id: '41',
            text: '订单查询',
            icon: 'icon-glass',
            url: '/Order/Query'
          }, {
            id: '42',
            text: '订单排产',
            icon: 'icon-glass',
            url: '/Order/PLANTPRODUCT'
          }, {
            id: '43',
            text: '订单撤排',
            icon: 'icon-glass',
            url: '/Order/cancelPRODUCT'
          }, {
            id: '44',
            text: '订单HOLD',
            icon: 'icon-glass',
            url: '/Order/hold'
          }, {
            id: '45',
            text: '订单删除',
            icon: 'icon-glass',
            url: '/Order/delete'
          }, {
            id: '47',
            text: '订单插单',
            icon: 'icon-glass',
            url: '/Order/insertorder'
          }, {
            id: '48',
            text: '订单导入',
            icon: 'icon-glass',
            url: '/Order/Import'
          }]
        }]
      });
    });

A very important point to note here is about the small icon in front of the menu:

When the value of con is icon-user, a small icon as shown in the picture will be displayed on the menu. Of course, under normal circumstances, the menu must be loaded dynamically. If you need to get data from the background, you can call this method directly:

$('#menu').sidebarMenu({ url: "/api/UserApi/GetMenuByUser/", param: { strUser: 'admin' } });
That’s it, haha, it’s very simple.

2. Tab page effect
The effect of the Tab page is actually closely related to the left menu. First, let’s take a look at the js reference of the Tab page effect.
bccd8ef0e7363ea609f854d3bba6a81e2cacc6d41bbb37262a98f745aa00fbf0
HTML tag of the page:
                                                                       

 <div class="main-content"><div class="page-content">
          <div class="row">
            <div class="col-xs-12" style="padding-left:5px;">
              <ul class="nav nav-tabs" role="tablist">
                <li class="active"><a href="#Index" role="tab" data-toggle="tab">首页</a></li>
              </ul>
              <div class="tab-content">
                <div role="tabpanel" class="tab-pane active" id="Index">
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>

The bootstrap-tab.js file encapsulates the addTabs method

var addTabs = function (options) {
  //var rand = Math.random().toString();
  //var id = rand.substring(rand.indexOf('.') + 1);
  var url = window.location.protocol + '//' + window.location.host;
  options.url = url + options.url;
  id = "tab_" + options.id;
  $(".active").removeClass("active");
  //如果TAB不存在，创建一个新的TAB
  if (!$("#" + id)[0]) {
    //固定TAB中IFRAME高度
    mainHeight = $(document.body).height() - 90;
    //创建新TAB的title
    title = '<li role="presentation" id="tab_' + id + '"><a href="#' + id + '" aria-controls="' + id + '" role="tab" data-toggle="tab">' + options.title;
    //是否允许关闭
    if (options.close) {
      title += ' <i class="glyphicon glyphicon-remove" tabclose="' + id + '"></i>';
    }
    title += '</a></li>';
    //是否指定TAB内容
    if (options.content) {
      content = '<div role="tabpanel" class="tab-pane" id="' + id + '">' + options.content + '</div>';
    } else {//没有内容，使用IFRAME打开链接
      content = '<div role="tabpanel" class="tab-pane" id="' + id + '"><iframe src="' + options.url + '" width="100%" height="' + mainHeight +
          '" frameborder="no" border="0" marginwidth="0" marginheight="0" scrolling="yes" allowtransparency="yes"></iframe></div>';
    }
    //加入TABS
    $(".nav-tabs").append(title);
    $(".tab-content").append(content);
  }
  //激活TAB
  $("#tab_" + id).addClass('active');
  $("#" + id).addClass("active");
};
var closeTab = function (id) {
  //如果关闭的是当前激活的TAB，激活他的前一个TAB
  if ($("li.active").attr('id') == "tab_" + id) {
    $("#tab_" + id).prev().addClass('active');
    $("#" + id).prev().addClass('active');
  }
  //关闭TAB
  $("#tab_" + id).remove();
  $("#" + id).remove();
};
$(function () {
  mainHeight = $(document.body).height() - 45;
  $('.main-left,.main-right').height(mainHeight);
  $("[addtabs]").click(function () {
    addTabs({ id: $(this).attr("id"), title: $(this).attr('title'), close: true });
  });

  $(".nav-tabs").on("click", "[tabclose]", function (e) {
    id = $(this).attr("tabclose");
    closeTab(id);
  });
});

So, when is the Addtabs method called? The answer is when registering the menu click event. This part of the code is available when the sidebar-menu component is encapsulated earlier. You can look at it above.

The above is a display of the menu and Tab page effects of the bootstrap ace template. In general, the basic functions are available, but the style of the menu needs to be adjusted. For example, after clicking a menu, the clicked menu needs to be selected. status. If your project also uses the bootstrap style, study the ace template and try it out.
