硒。JavascriptException:javascript错误：未能对“文档”执行“elementFromPoint”：提供的双精度值是非有限的

Question

使用Chrome78和chromedriver78当我单击音频文件或尝试使用selenium tests停止音频时，我遇到此错误。

错误：

org.openqa.selenium.JavascriptException: javascript error: Failed to execute 'elementsFromPoint' on 'Document': The provided double value is non-finite.

请注意，这种情况只发生在远程webdriver上，并且不一致。

错误堆栈跟踪：

当“item_1”元素的音频播放器在“[data rcfid='checkbox_7']中停止时

org.openqa.selenium.JavascriptException: javascript error: Failed to execute 'elementsFromPoint' on 'Document': The provided double value is non-finite.

Answer 1

我在尝试单击AngularJS网格中的单元格时遇到了同样的问题。我确认XPath查询只产生一个结果，然后研究添加等待条件是否有帮助。正如添加错误一样，允许在此处继续添加，而不允许在此处等待。

下面的代码是我用来单击单元格的方法。我从Click（）切换到了Action，因为Click（）方法被另一个元素截获。

public void ClickEmploymentChangeLogButton()
{
    Wait.Until(WaitConditions.ElementIsVisibleAndEnabled(EmploymentChangeLogButton));
    Actions actions = new Actions(driver);
    actions.MoveToElement(EmploymentChangeLogButton).Perform();
    actions.MoveToElement(EmploymentChangeLogButton).Click().Perform();
}

WaitConditions是一个单独的类，用于对不推荐使用的ExpectedConditions包的某些行为进行建模。

下面是上面使用的WaitConditions内部的方法。

public static Func<IWebDriver, bool> ElementIsVisibleAndEnabled(IWebElement element)
{
    return (driver) =>
    {
        try
        {
            return element.Displayed && element.Enabled;
        }
        catch (Exception)
        {
            // If element is null, stale or if it cannot be located
            return false;
        }
    };
}

我也遇到过同样的问题，只需将窗口向下滚动到目标元素，就可以解决这个问题。元素似乎没有显示在视口中，这就是为什么selenium看不到它的原因。

在找到并单击元素之前，尝试添加以下行：

driver.execute_script("window.scrollTo(0, window.scrollY + 100)")
driver.implicitly_wait(3) 

Answer 3

我也有同样的问题，观察结果是，同一个xpath有多个元素。找到不同的唯一xpath解决了这个问题
