javascript - 用 span 替换标签

Question

我正在使用 AngularJS 和 mmenu 制作菜单，但我有一些子菜单无法正确用作子菜单。本质上，mmenu 将跨度视为菜单，当您单击它时，它会展开(或尝试)并将标签视为链接，当您单击它时，菜单会关闭并尝试将您发送到链接。问题是，当我使用 ng-repeat 构建菜单时，我的一些项目是链接(a)，有些项目应该有进一步的子菜单，使它们具有跨度。我可以想出几种方法来解决这个问题，但我似乎无法使它们发挥作用，以下是我尝试过的解决方案:

1. 使用 ng-click 函数运行 if 语句来查看单击的菜单是否有嵌套 ul，如果有，则添加类 mm.opened 来展开子菜单，而不是点击链接

2. 使用函数在构建后运行整个菜单并找到任何 <a>具有嵌套 ul 的标签，并将 a 标签替换为 span ("span"+ this.innerHTML + "/span")

3. 寻求帮助(当前步骤)

我确实对任何解决方案持开放态度，我的 Angular 可能是错误的，这可能导致我所有的问题，所以请随时纠正我。

我无法附加工作示例，因为我的菜单是从 json 文件构建的，并且我无法将 json 导入到代码编辑器(据我所知)

这是我的菜单:

<ul>
  <li><a ng-href="#/home" class="menuBtn">Home</a></li>
  <li ng-repeat="menu in menuInfo" ng-class="countDisable(menu.schematics.length, menu)"> <a class="menuBtn">ATA {{menu.ata}} - {{menu.name}}</a>
    <ul>
      <li ng-click="subCheck()" ng-repeat="submenu in menu.schematics"><a ng-href="#{{submenu.view}}" class="menuBtn">{{submenu.name}}</a>
        <ul>
          <li ng-repeat="animated in submenu.subs"><a ng-href="#{{animated.view}}" ng-click="contentCtrl(animated)" class="menuBtn">{{animated.name}}</a></li>
        </ul>
      </li>
    </ul>
  </li>
</ul>

它看起来像这样:

当我单击 ATA 29 时，它会扩展为:

你会看到 ATA 29 有 4 个项目，其中 3 个应该是常规链接，第一个也有四个嵌套项目，所以当我单击它时，我希望它像 ATA 29 一样展开，但是相反，它认为它是一个链接，所以它这样做:

我意识到如果没有工作代码就很难提供帮助，但任何帮助将不胜感激。

Answer 1

• 同级 li 未关闭，并且已成为嵌套菜单，而没有正确设置为子菜单。

• li 没有生成我期望的 span 。所以我只是复制了我在顶部菜单中看到的模式，它就起作用了。

更改此:

 <li ng-repeat="submenu in secMenuInfo">
   <a ng-href="#{{submenu.view}}" class="menuBtn">{{submenu.name}}</a>
   <li ng-repeat="submenu in secMenuInfo">
     <a ng-href="#{{submenu.view}}" class="menuBtn">{{submenu.name2}}</a>

对此:

 <li ng-repeat="submenu in secMenuInfo">
    <a ng-href="#{{submenu.view}}" class="menuBtn">{{submenu.name}}</a>
 </li>
 <li ng-repeat="submenu in secMenuInfo">
    <span class="menuBtn">{{submenu.name2}}</span>
