我看到有一个问题:Selenium-Webdriver Ruby --> 如何在单击后等待图像完全加载。
但似乎没有人直接回答:我需要等待图像完全加载,而不仅仅是出现在DOM中,使用selenium WebDriver。我该怎么办?目前我正在使用
public static void waitUntilVisible(WebDriver webDriver, By locator) {
WebDriverWait driverWait = new WebDriverWait(webDriver, TIMEOUT);
driverWait.until(visibilityOfElementLocated(locator));
}
这使用了
/**
* 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.
*
* @param locator used to find the element
* @return the WebElement once it is located and visible
*/
public static ExpectedCondition<WebElement> visibilityOfElementLocated(
final By locator) {
return new ExpectedCondition<WebElement>() {
@Override
public WebElement apply(WebDriver driver) {
try {
return elementIfVisible(findElement(locator, driver));
} catch (StaleElementReferenceException e) {
return null;
}
}
@Override
public String toString() {
return "visibility of element located by " + locator;
}
};
}
但是,如果一张图片已经有了高度和宽度,即使图片没有加载完成,它可能被视为可见。
