driver.switchTo().frame(int arg0);

如果一個頁面有多個iframe（超過1個），第一個iframe將位於索引“0”，第二個的為“1”，以此類推

public void switchToFrame(int frame) {
		try {
			driver.switchTo().frame(frame);
			System.out.println("Navigated to frame with id " + frame);
		} catch (NoSuchFrameException e) {
			System.out.println("Unable to locate frame with id " + frame
					+ e.getStackTrace());
		} catch (Exception e) {
			System.out.println("Unable to navigate to frame with id " + frame
					+ e.getStackTrace());
		}
	}
 

driver.switchTo().frame(String arg0);

frame 的名稱或者id

public void switchToFrame(String frame) {
		try {
			driver.switchTo().frame(frame);
			System.out.println("Navigated to frame with name " + frame);
		} catch (NoSuchFrameException e) {
			System.out.println("Unable to locate frame with id " + frame
					+ e.getStackTrace());
		} catch (Exception e) {
			System.out.println("Unable to navigate to frame with id " + frame
					+ e.getStackTrace());
		}
	}
 

driver.switchTo().frame(WebElement frameElement);

入參為該frame的元素element

public void switchToFrame(WebElement frameElement) {
		try {
			if (isElementPresent(frameElement)) {
				driver.switchTo().frame(frameElement);
				System.out.println("Navigated to frame with element "+ frameElement);
			} else {
				System.out.println("Unable to navigate to frame with element "+ frameElement);
			}
		} catch (NoSuchFrameException e) {
			System.out.println("Unable to locate frame with element " + frameElement + e.getStackTrace());
		} catch (StaleElementReferenceException e) {
			System.out.println("Element with " + frameElement + "is not attached to the page document" + e.getStackTrace());
		} catch (Exception e) {
			System.out.println("Unable to navigate to frame with element " + frameElement + e.getStackTrace());
		}
	}

iframe巢狀情況

public void switchToFrame(String ParentFrame, String ChildFrame) {
		try {
			driver.switchTo().frame(ParentFrame).switchTo().frame(ChildFrame);
			System.out.println("Navigated to innerframe with id " + ChildFrame
					+ "which is present on frame with id" + ParentFrame);
		} catch (NoSuchFrameException e) {
			System.out.println("Unable to locate frame with id " + ParentFrame
					+ " or " + ChildFrame + e.getStackTrace());
		} catch (Exception e) {
			System.out.println("Unable to navigate to innerframe with id "
					+ ChildFrame + "which is present on frame with id"
					+ ParentFrame + e.getStackTrace());
		}
	}

切換到預設iframe

public void switchtoDefaultFrame() {
		try {
			driver.switchTo().defaultContent();
			System.out.println("Navigated back to webpage from frame");
		} catch (Exception e) {
			System.out
					.println("unable to navigate back to main webpage from frame"
							+ e.getStackTrace());
		}
	}
