Question

这是我的第一条消息，主要是因为这是我第一次无法找到问题的答案。

我正在尝试计算下拉列表中li元素的数量。每个<li> has a`链接。这是HTML代码：

<div ko-dropdown="ko-dropdown" ng-keyup="onKeyup($event)" ng-keydown="onKeydown($event)" class="dropdown ng-isolate-scope" ta-items="languages" ta-value="language" ta-onselect="select(lang)">
  <div ng-click="toggle()" ng-class="{'is-open': open}" class="dropdown__toggle  dropdown__toggle--top">English</div>
  <ul ko-drop-menu="ko-drop-menu" ng-mouseleave="onMouseLeave($event)" class="dropdown__menu">
    <!-- ngRepeat: item in items track by $index -->
    <li ko-drop-item="ko-drop-item" ng-repeat="item in items track by $index" ng-mouseenter="onMouseEnter($event, item)" ng-click="select($event, item)" ng-class="{'is-active': item.selected}" class="dropdown__item ng-scope is-active"><a class="dropdown__link ng-binding ng-scope" href="" ng-bind="::item[label]" data-value="en">English</a>
    </li>
    <!-- end ngRepeat: item in items track by $index -->
    <li ko-drop-item="ko-drop-item" ng-repeat="item in items track by $index" ng-mouseenter="onMouseEnter($event, item)" ng-click="select($event, item)" ng-class="{'is-active': item.selected}" class="dropdown__item ng-scope"><a class="dropdown__link ng-binding ng-scope" href="" ng-bind="::item[label]" data-value="fi">Suomi</a>
    </li>
    <!-- end ngRepeat: item in items track by $index -->
    <li ko-drop-item="ko-drop-item" ng-repeat="item in items track by $index" ng-mouseenter="onMouseEnter($event, item)" ng-click="select($event, item)" ng-class="{'is-active': item.selected}" class="dropdown__item ng-scope"><a class="dropdown__link ng-binding ng-scope" href="" ng-bind="::item[label]" data-value="sv">Svenska</a>
    </li>
    <!-- end ngRepeat: item in items track by $index -->
    <li ko-drop-item="ko-drop-item" ng-repeat="item in items track by $index" ng-mouseenter="onMouseEnter($event, item)" ng-click="select($event, item)" ng-class="{'is-active': item.selected}" class="dropdown__item ng-scope"><a class="dropdown__link ng-binding ng-scope" href="" ng-bind="::item[label]" data-value="no">Norsk</a>
    </li>
    <!-- end ngRepeat: item in items track by $index -->
    <li ko-drop-item="ko-drop-item" ng-repeat="item in items track by $index" ng-mouseenter="onMouseEnter($event, item)" ng-click="select($event, item)" ng-class="{'is-active': item.selected}" class="dropdown__item ng-scope"><a class="dropdown__link ng-binding ng-scope" href="" ng-bind="::item[label]" data-value="de">Deutsch</a>
    </li>
    <!-- end ngRepeat: item in items track by $index -->
  </ul>
</div>

量角器应返回的正确元素数量为5，但在查找元素数量时，我总是得到10个。

我正在使用这段代码来调用，但正如之前所说，我总是得到10甚至与dropdown__link等结合：

`elements.all(by.css('.dropdown__menu .dropdown__item')).count()`

Answer 1

让你的选择更具体：

div[ta-items=languages] ul.dropdown__menu > li.dropdown__item

或者，通过链接element和element.all以及by.repeater：

var languageMenu = element(by.css("div[ta-items=languages]"));
var languages = languageMenu.all(by.repeater("item in items"));

expect(languages.count()).toEqual(5);

Answer 2

arr=browser.driver.findElement(by.tagName("a"));

for(var x = 0; x < arr.count; x++) 
{
    console.log('vishnu');
    console.log(arr[i]);
}

量角器无法计算列表中的链接（li）
