如何单击Selenium Webdriver中的所有元素?

已更新

我正在使用:

• 硒2.53.1
• Firefox和IE11

我一直试图单击具有相同选择器的所有元素，例如，我想单击标题为"What I Want"的所有元素:

I've been trying to click on all elements with the same selector, for example, I want to click on all the ones with the title "What I Want":

<div id="first_question">
<a class="gibberish1" title="What I Want"></a>
<a class="gibberish2" title="What I Want"></a>
<a class="gibberish3" title="What I Want"></a>
</div>

这是我到目前为止的工作:

Here is what I have working so far:

browser.findElements(by.xpath("//a[@title='What I Want']")).then(function(all_tests){
           for (var i = 0; i < all_tests.length; i++) {
               console.log(all_tests.length);
               all_tests[i].click();
           }
    });

能够识别出我有三个元素，如果直接调用每个元素，那么我可以在按钮上看到它.但是，当我要循环以使其单击每个按钮时，出现错误:

It's able to recognize that I have three elements, and if I call each individual one directly then I'm able to see it click on the button. However, when I want to loop so it clicks on each button, I get an error:

"StaleElementReferenceError:元素不再附加到DOM."

"StaleElementReferenceError: Element is no longer attached to the DOM."

我还增加了5秒的等待时间，但这并没有阻止弹出同样的问题.

I also added a wait of 5 seconds in, but that didn't deter the same issue from popping up.

我做错了什么?我是Selenium的新手，我试图用Javascript来解决这个问题，而不是用Java来找到这种情况的例子.

What am I doing wrong? I'm new to Selenium and I'm trying to figure this out in Javascript, instead of Java which is what I find examples for this situation.
