尝试单击下拉框中的超链接时遇到错误。我尝试了几个选项（我将在下面发布），但我不断收到错误unable to locate the element或element not visible。如果我试着等待，我会得到一个超时错误。
看起来我的代码无法找到我想要点击的元素。
奇怪的是，如果我在irb中运行命令，我可以使用文本点击链接。
所以我希望有人打电话帮助我，因为我无法弄清楚我错过了什么。
这就是我拥有的以及我想要做的事情。
我的网页上有多张卡片。我想选择第一张卡 - 这是一个下拉箭头 - 我能够做到。单击箭头后，它会显示另一个下拉框，其中包含我要单击的项目列表，具体取决于我要测试的内容。我可以单击箭头查看下拉框，但是当我尝试单击此下拉列表中的超链接时，我会收到错误。
这就是网页的样子（抱歉无法提供实际页面的链接）
cardxxxxxxxx（点击箭头），我
I would like to (drop down box.Click on arrow,I get)
View card features
Dispute a transaction
Request a plastic card
View all transactions
这里有其他一些东西。 然后我有下一张卡
cardxxxxxxxxx
在下拉和链接等方面与上面完全相同。
我希望能够点击第一张卡的下拉框（例如查看所有交易）中的超链接。如果没有上面提到的错误，我该怎么做呢？
我想最终能够说点击第二张卡并点击该卡下拉框中的超链接（这将是一个单独的测试用例）。
这是我的代码;我在firefox中尝试这个。
$b.image(:alt, "Actionbuttondown").click
#$b.link(:class, 'viewAllTransactions').wait_until_present
#$b.link(:text, "View all transactions").click
#$b.link(:class, "viewAllTransactions").click
#$b.link(:text, "View all transactions").when_present.click
#$b.div(:class, 'actionMenuContainer').as[0].when_present.click
#$b.link(:text, 'View all transactions').hover
#$b.link(:text, 'View all transactions').flash
#$b.link(:text, 'View all transactions').when_present.click
#$b.link(:text, 'View all transactions').click
#$b.link(:text, "View all transactions").flash
#$b.link(:text, "View all transactions").click
#$b.button(:id, 'btnPages').wait_until_present
#$b.link(:href, "/cards/details/xxxxxx-xxx/transaction_history? card_id=xxxxxxxxxxxxx").hover
#$b.link(:href, "/cards/details/xxxxx-xxx/transaction_history?card_id=xxxxxxxxxxxxxx").when_present.click
$b.link(:class => 'actionMenuItems', :text => "View all transactions").click
这是页面上的html：
<div class="hiddenDetails" style="display: block;">
<div class="actionMenuContainer">
<div class="actionMenu">
<h1>I would like to…</h1>
<div class="actionMenuIcon"><img alt="Actionbuttondown" src="/images/actionButtonDown.png?xxxxxxxxx"></div>
<div class="actionMenuItems">
<div class="actionMenuItems" style="position: absolute; left: 1105.5px; top: 365px; width: 177px; display: block;">
<a href="/cards/details/xxxxxx-xxxl?card_id=xxxxxxxxxxxxx" class="viewAllTransactions">View card features</a>
<a href="/site/dispute-transaction?account_id=xxxxxxxxxxxxx" class="viewAllTransactions">Dispute a transaction</a>
<a href="/users/request-card/xxxxxxxxxxxxxxxxxx=" class="requestPlasticAction">Request a plastic card</a>
<a href="/cards/details/xxxxxx-xxx/transaction_history?card_id=xxxxxxxxxxxxx" class="viewAllTransactions">View all transactions</a>
</div>
感谢任何帮助。我花了很多时间试图解决这个问题而没有成功。请帮忙。
回应您的意见：
这是我正在尝试做的事情，我将包括实际的watir代码。
Go to url
Enter username password
click on a drop down box
click on hyperlink (View all transactions)
这是有问题的watir代码。
$b.image(:alt, "Actionbuttondown").click (workks and shows the drop down box).
$b.link(:text, "View all transactions").click (fails with error).
以下是我收到的错误消息。

这是我在irb中尝试过的作品
browser3.image(:alt, "Actionbuttondown").click
browser3.link(:text, "View all transactions").click
希望现在更有意义，你可以指出我正确的方向。
