如何使用Java在Selenium WebDriver中切换帧

Question

I am using java with WebDriver.I have to switch between two frames. I have recorded the test case in selenium IDE and in that I got the values as selectFrame relative=top select Frame=middle Frame

But there is a problem it is not able to recognize the relative=top and middleFrame. How can I solve this problem in Selenium WebDriver with Java?

Answer 1

WebDriver's driver.switchTo().frame() method takes one of the three possible arguments:

• A number.

  Select a frame by its (zero-based) index. That is, if a page has three frames, the first frame would be at index 0 , the second at index 1 and the third at index 2 . Once the frame has been selected, all subsequent calls on the WebDriver interface are made to that frame.

• A name or ID.

  Select a frame by its name or ID. Frames located by matching name attributes are always given precedence over those matched by ID.

• A previously found WebElement .

  Select a frame using its previously located WebElement.

Get the frame by it's id/name or locate it by driver.findElement() and you'll be good.

Answer 2

to switchto a frame:

driver.switchTo.frame("Frame_ID");

to switch to the default again.

driver.switchTo().defaultContent();

Answer 3

First you have to locate the frame id and define it in a WebElement

For ex:- WebElement fr = driver.findElementById("id");

Then switch to the frame using this code:- driver.switchTo().frame("Frame_ID");

An example script:-

WebElement fr = driver.findElementById("theIframe");

driver.switchTo().frame(fr);

Then to move out of frame use:- driver.switchTo().defaultContent();

This code is in groovy, so most likely you will need to do some rework. The first param is a url, the second is a counter to limit the tries.

public boolean selectWindow(window, maxTries) {
    def handles
    int tries = 0
    while (true) {
        try {
            handles = driver.getWindowHandles().toArray()
            for (int a = handles.size() - 1; a >= 0 ; a--) { // Backwards is faster with FF since it requires two windows
                try {
                    Log.logger.info("Attempting to select window: " + window)
                    driver.switchTo().window(handles[a]);
                    if (driver.getCurrentUrl().equals(window))
                        return true;
                    else {
                        Thread.sleep(2000)
                        tries++
                    }
                    if (tries > maxTries) {
                        Log.logger.warn("Cannot select page")
                        return false
                    }
                } catch (Exception ex) {
                    Thread.sleep(2000)
                    tries++
                }
            }
        } catch (Exception ex2) {
            Thread.sleep(2000)
            tries++
        }
    }
    return false;
}

Answer 5

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

Answer 6

You can also use:

driver.switch_to.frame(0)

(0) being the first iframe on the html.

to switch back to the default content:

driver.switch_to.default_content()

Answer 7

There is also possibility to use WebDriverWait with ExpectedConditions (to make sure that Frame will be available).

1. With string as parameter

    (new WebDriverWait(driver, 5)).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("frame-name")); 

2. With locator as a parameter

    (new WebDriverWait(driver, 5)).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("frame-id")));
