要模拟ExpectedConditions,您elementNotExists
可以使用 betweeninvisibilityOfElementLocated()
或invisibilityOf()
。
invisibilityOfElementLocated()
invisibilityOfElementLocated()是一种实现,用于检查元素是否不可见或不存在于 DOM 上。定义如下:
public static ExpectedCondition<java.lang.Boolean> invisibilityOfElementLocated(By locator)
An expectation for checking that an element is either invisible or not present on the DOM.
Parameters:
locator - used to find the element
Returns:
true if the element is not displayed or the element doesn't exist or stale element
代码块:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.WebDriverWait;
public class fooPage {
WebDriver driver;
public fooPage(WebDriver driver)
{
PageFactory.initElements(driver, this);
}
//you don't need this
//@FindBy(className = "loading-container")
//private WebElement loadingElement;
public void foo()
{
Boolean bool = new WebDriverWait(driver, 20).until(ExpectedConditions.invisibilityOfElementLocated(By.className('loading-container')));
//other lines of code
}
}
作为替代方案,您还可以使用以下invisibilityOf()
方法:
隐形()
invisibilityOf()是检查元素是否不可见的期望的实现。定义如下:
public static ExpectedCondition<java.lang.Boolean> invisibilityOf(WebElement element)
An expectation for checking the element to be invisible
Parameters:
element - used to check its invisibility
Returns:
Boolean true when elements is not visible anymore
代码块:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.WebDriverWait;
public class fooPage {
WebDriver driver;
public fooPage(WebDriver driver)
{
PageFactory.initElements(driver, this);
}
@FindBy(className= 'loading-container')
WebElement loadingElement;
public void foo()
{
Boolean bool = new WebDriverWait(driver, 20).until(ExpectedConditions.invisibilityOf(fooPage.getWebElement()));
//other lines of code
}
public WebElement getWebElement()
{
return loadingElement;
}
}
