Angular JS中的Bootstrap Dropdownlist问题 [英] Bootstrap Dropdownlist Issue in angular JS

问题描述

我正在尝试在bootstrap下拉菜单中使用ng-repeat，但是它不显示下拉列表中的元素列表.在控制器中定义的方法中填充下拉列表的元素时，我是否缺少任何内容.

<button type="button" class="btn btn-default btn-sm" title="Results Per Page">
  <span class="dropdown" dropdown>
     <a href class="dropdown-toggle" dropdown-toggle>
       <span class="caret"></span>
      {{Temp.obj.pageSize}} Results Per Page </a>     
          <ul class="dropdown-menu">
            <li data-ng-repeat="result in Temp.obj.availPages">
            <a href data-ng-click="Temp.obj.setSize(result)">                            
                 {{result}}</a>
            </li>
           </ul>
    </span>
</button>

解决方案

您很容易在ul列表中缺少dropdown-menu指令.

提醒一下，这是angular-ui引导文档中的(简化)示例.

<div class="btn-group" uib-dropdown>
  <button id="single-button" type="button" class="btn btn-primary" uib-dropdown-toggle>
    Button dropdown <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" uib-dropdown-menu role="menu" aria-labelledby="single-button">
    <li role="menuitem"><a href="#">Action</a></li>
    <li role="menuitem"><a href="#">Another action</a></li>
  </ul>
</div>

当指令没有以uib-为前缀时，您似乎正在使用旧版本的angular-ui引导程序.如果可以的话，我建议您更新版本.否则，只需从示例中删除前缀即可.

当您使用angular-ui引导程序的1.1.2版本时，需要在指令前面加上此答案中所示的前缀.这是参考文档

I am trying to use ng-repeat in bootstrap dropdown menu, but it does not display the list of elements in drop down. am i missing anything in populating the elements of drop down list from a method defined in controller.

<button type="button" class="btn btn-default btn-sm" title="Results Per Page">
  <span class="dropdown" dropdown>
     <a href class="dropdown-toggle" dropdown-toggle>
       <span class="caret"></span>
      {{Temp.obj.pageSize}} Results Per Page </a>     
          <ul class="dropdown-menu">
            <li data-ng-repeat="result in Temp.obj.availPages">
            <a href data-ng-click="Temp.obj.setSize(result)">                            
                 {{result}}</a>
            </li>
           </ul>
    </span>
</button>

解决方案

You are simple missing the dropdown-menu directive in the ul list.

As a reminder, here is the (simplified) example from the angular-ui bootstrap doc.

<div class="btn-group" uib-dropdown>
  <button id="single-button" type="button" class="btn btn-primary" uib-dropdown-toggle>
    Button dropdown <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" uib-dropdown-menu role="menu" aria-labelledby="single-button">
    <li role="menuitem"><a href="#">Action</a></li>
    <li role="menuitem"><a href="#">Another action</a></li>
  </ul>
</div>

It looks like you are using an old version of angular-ui bootstrap when the directive were not prefixed by uib-. I recommend updating your version if you can. Otherwise, just remove the prefixs from the example.

Edit: As you are using the version 1.1.2 of angular-ui bootstrap, you need to prefix the directives as shown in this answer. And here is the doc for reference
