Watir webdriver;计数具有更改类名称的元素 [英] Watir webdriver; counting elements with changing class names

问题描述

我使用Rspec和Watir-webdriver，并且希望获得点击的所有元素的计数。

I am using Rspec and Watir-webdriver and am looking to get a count of all the elements that have been clicked.

我在做什么：

我执行搜索并返回结果列表;然后我运行一个循环，只选择其中的5。这些元素的类名从资产卡选择到现在说资产卡可选择。

I perform a search and get back a list of results; I then run a loop to select only 5 of them. The class name for these elements goes from asset-card selectable to now saying asset-card selectable selected.

我尝试通过这样做正确计数：

I try to get a proper count by doing this:

count = @browser.elements(:class, 'selected').size

> all 结果，而不是现在已经选择 作为类名的一部分。

But this is still giving me all results and not specifically the ones that now have selected as part of the class name.

任何想法如何我可以完成这个？
这是html的样子：

Any thoughts on how I can accomplish this?
This is what the html looks like:

<div class="search results">
    <div class="asset-card selectable selected"></div>
    <div class="asset-card selectable selected"></div>
    <div class="asset-card selectable"></div>
    <div class="asset-card selectable"></div>
    <div class="asset-card selectable"></div>
</div>

在此HTML示例中，选择了前两个元素

In this html example, the first two elements have been selected

推荐答案

我感觉很蠢;我找到一个解决方案，修正为什么我没有得到一个正确的计数返回：这是因为我不等待足够长的时间



在我放置一个 sleep 1 时间后，它返回一个计数准确的我点击。我的想法不完全是技术，但它的行为好像点击操作和类名更改执行操作之前，可以确定正确的计数。
我会寻找一个更优雅的等待解决方案，因为我想避免不必使用 sleep 命令（如果可能）

I feel rather dumb; I found a solution that fixes the issue of why I wasn't getting a proper count returned: it's because I wasn't waiting long enough

After I placed a sleep 1 duration, it returned a count accurate to what I was clicking on. My thought on this isn't exactly technical, but it was acting as if the click action and class name change was performing actions before a proper count could be determined.
I will be looking to place a more elegant wait solution as I'd like to avoid having to use sleep commands if possible
