针对页面上的二级菜单，需要鼠标悬停才能进行操作。
/**
* Clicks (without releasing) in the middle of the given element. This is equivalent to:
* <i>Actions.moveToElement(onElement).clickAndHold()</i>
*
* @param onElement Element to move to and click.
* @return A self reference.
*/
public Actions clickAndHold(WebElement onElement) {
action.addAction(new ClickAndHoldAction(mouse, (Locatable) onElement));
return this;
}
使用方法：最后一定不要忘记perform()
Actions actions = new Actions(driver);
actions.clickAndHold(webElement).perform();
或者：
Actions actions = new Actions(driver);
actions.moveToElement(webElement).clickAndHold().perform();
或者：使用js来模拟鼠标悬停
/**
* JScript实现鼠标悬停
* @author lozz
*/
public void mouseHoverJScript(WebElement HoverElement) {
// TODO Auto-generated method stub
try {
if (isElementPresent(HoverElement)) {
String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
((JavascriptExecutor) driver).executeScript(mouseOverScript, HoverElement);
} else {
System.out.println("Element was not visible to hover " + "\n");
}
} catch (StaleElementReferenceException e) {
// TODO: handle exception
System.out.println("Element with " + HoverElement + "元素未附加到页面文档" + e.getStackTrace());
} catch (NoSuchElementException e) {
// TODO: handle exception
System.out.println("Element " + HoverElement + " 元素未在DOM中没有找到" + e.getStackTrace());
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
System.out.println("悬停时发生错误" + e.getStackTrace());
}
}
