我给了两个条件,webdriver在继续执行之前需要等待两个条件之一满足。为此,我正在使用显式等待以及ExpectedConditions.or
。
我尝试使用以下代码:
new WebDriverWait(driver.getDriver(),30).until(
ExpectedConditions.or(
ExpectedConditions.jsReturnsValue("return document.ReadyState")).equals("complete"),
ExpectedConditions.visibilityOfElementLocated(driver.findElement(By.Id("name"))
)
);
我收到错误消息:
The method until(Function<? super WebDriver,V>) in the type FluentWait<WebDriver> is not applicable for the arguments (boolean, ExpectedCondition<WebElement>)
请注意,我使用的是Guava 23.0,它已作为依赖项添加到pom.xml中。

ExpectedConditions.or
接收ExpectedCondition
作为参数。当您将ExpectedConditions.jsReturnsValue
的结果与字符串进行比较时,会将所有表达式都更改为boolean
。
您可以创建自定义ExpectedCondition
来变形
public static ExpectedCondition<Object> customeJsReturnsValue(final String javaScript) {
return new ExpectedCondition<Object>() {
@Override
public Object apply(WebDriver driver) {
return ExpectedConditions.jsReturnsValue("return Spotfire.Busy.idle()")).equals("true")
}
}
}
用途:
new WebDriverWait(driver.getDriver(),30).until(
ExpectedConditions.or(
customeJsReturnsValue("return document.ReadyState")).equals("complete"),
ExpectedConditions.visibilityOfElementLocated(driver.findElement(By.Id("name"))
)
);

jsReturnsValue()
的 ExpectedConditions 返回 Object ,并定义为:
public static ExpectedCondition<java.lang.Object> jsReturnsValue(java.lang.String javaScript)
An expectation for String value from javascript
Parameters:
javaScript - as executable js line
Returns:
true once js return string
visibilityOfElementLocated()
的 ExpectedConditions 返回 WebElement ,并定义为:
public static ExpectedCondition<WebElement> visibilityOfElementLocated(By locator)
An expectation for checking that an element is present on the DOM of a page and visible. Visibility means that the element is not only displayed but also has a height and width that is greater than 0.
Parameters:
locator - used to find the element
Returns:
the WebElement once it is located and visible
此错误消息...
The method until(Function<? super WebDriver,V>) in the type FluentWait<WebDriver> is not applicable for the arguments (boolean, ExpectedCondition<WebElement>)
...表示until()
不适用于多种返回类型boolean
和WebElement
。
在您的用例中,
jsReturnsValue()
返回一个 Object 。visibilityOfElementLocated()
返回一个 WebElement 。如果您的用例是关于某个 WebElement 的可见性的,则可以放心地忽略对'document.readyState'等于“ complete”的关注< / strong>,因为这将是一项开销。您可以在Selenium IE WebDriver only works while debugging中找到相关的讨论。
但是,要将until()
的{{1}}用于类似类型数据类型的多个元素,可以遵循以下示例:
等待visibilityOfElementLocated()
或By.xpath("//span[@id='id1']")
中的任意一个元素就像:
By.xpath("//span[@id='id2']")
您可以在
中找到一些相关的详细讨论。Do we have any generic function to check if page has completely loaded in Selenium
