Question

我正在努力使用visibilityOfElementLocated

的语法

我有一个表格行的元素，现在我需要搜索此行中的元素，如row.findElement(xxx)

以下是我们用于直接在页面

上定位元素（父级）的语法

WebDriverWait wait = new WebDriverWait(driver, 90L);
WebElement data=wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath
                ("./td[" + columnIdx + "]");

所以问题是如何在tableRow上使用上面的等待？（例如tableRow。（wait.until））

谢谢！

Answer 1

如果您已经定义了webelement row并且想在此td中找到子/后代row元素，则可以替换

WebDriverWait wait = new WebDriverWait(driver, 90L);

与

WebDriverWait wait = new WebDriverWait(row, 90L);

Answer 2

您可以使用elementToBeClickable代替visibilityOfElementLocated

WebDriverWait wait = new WebDriverWait(wb, 60);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("value")));

这将等待每个网页元素60秒。

Answer 3

怎么样，你可以使用父元素找到子元素。

    WebDriverWait wait = new WebDriverWait(driver,30);
    wait.until(ExpectedConditions.visibilityOf(row.findElement(By.xpath("./td[" + columnIdx + "]"))));

Answer 4

您还可以使用 presenceOfNestedElementLocatedBy 函数：

WebElement childElem = wait.until(
    ExpectedConditions.presenceOfNestedElementLocatedBy(parentElem, By.xpath(xpath)));

Answer 5

I was trying to figure out solution for this problem too.

The parameter to wait.Until method is in C# just a method with following signature Func<IWebDriver, IWebElement> (i.e. function with one parameter - the driver - returning the found element.

So instead of trying to hack the Selenium library, I don't have to call the predefined ExpectedConditions (like ExpectedConditions.ElementExists) methods and I can only pass function that does what I need.

var parent = ... // an element I want to start the search from
// find the element using the XPath expression starting at the parent element
wait.Until(driver => parent.FindElement(By.XPath("..."));

Answer 6

这里没有一个解决方案对我有用。

对于Java或C＃，我只是将其重写为单个选择器。因此，如果您想要实现的原始（不可能）代码如下所示：

var tableRow = driver.FindElement(By.CssSelector("tr:nth-child(3)"));
var wait = new WebDriverWait(tableRow , new TimeSpan(0, 0, 10));
var td = wait.until(ExpectedConditions.VisibilityOfElementLocated(By.CssSelector("td:nth-child(1)");

只需将其更改为单个选择器，然后让您的网络驱动程序等待该选择器。

    var wait = new WebDriverWait(driver, new TimeSpan(0, 0, 10));
    var element = wait.Until(ExpectedConditions.VisibilityOfElementLocated(By.CssSelector("tr:nth-child(3) > td:nth-child(1)")));

您也应该能够使用XPath做同样的事情

如何为子元素等waitOfElementLocated？
