无法从嵌套框架切换到主页

Question

我有一个程序可以在 PLM 平台 ENOVIA 上自动输入数据，其中包含我输入的特定信息。我正在使用 Selenium 浏览网页。有一段程序必须输入 4 个嵌套帧才能单击某个元素。它做得很好并进行了必要的编辑，我面临的问题是，当我尝试使用 switch_to.default_content() 退出框架回到 HTML 代码的顶部以返回主页时。出于某种原因，在它切换到嵌套框架的第 4 个子框架并进行这些编辑后，我看到窗口更改为仅包含这些框架及其中的内容，而第一个父框架之上没有任何内容。所以 switch_to.default_content() 似乎不起作用。

这是真正重要的代码，它切换到第四帧和最后一帧“DSCObjectSummary”并进行这些编辑

def clickCheck(Method, Locator, elemName):
    #Add If Else to check for element availibility
    #Do Retries of searchess
    try:
        wait.until(EC.element_to_be_clickable((Method, Locator)))
        print(elemName + ' Clickable')
    except NoSuchElementException:
        print("Cannot Find Element")

...... Lots of code and comes to this point
    #Switching into 4 nested frames to click "EDIT DETAILS" Button
    wait.until(EC.frame_to_be_available_and_switch_to_it("content"))
    wait.until(EC.frame_to_be_available_and_switch_to_it("detailsDisplay"))
    wait.until(EC.frame_to_be_available_and_switch_to_it("portalDisplay"))
    wait.until(EC.frame_to_be_available_and_switch_to_it("DSCObjectSummary"))
    clickCheck(By.ID, 'DSCEditObjectSummary', "Edit Details")
    elemEdit = browser.find_element_by_id("DSCEditObjectSummary")
    elemEdit.click()

    #Click the Customer Dropdown
    clickCheck(By.ID, "PMCCustomerId", "Customer Dropdown")
    elemCust = browser.find_element_by_id("PMCCustomerId")
    elemCust.click()
    elemCust.send_keys("Ces")
    """Add If Conditions to check part number"""

    #Click Document Type Field
    clickCheck(By.ID, "PMCDocumentTypeId", "Document Type")
    elemDoc = browser.find_element_by_id("PMCDocumentTypeId")
    elemDoc.click()
    elemDoc.send_keys("MOD")

    """Add Check to see if part is Active/Obsol, if Obs, make Active"""

    #Click Dashnumber field
    clickCheck(By.ID, "PMCDashNumber", "Dash Number")
    elemDash = browser.find_element_by_id("PMCDashNumber")
    elemDash.click()
    elemDash.clear()
    elemDash.send_keys("-1")

    #Click Done Button
    clickCheck(By.CSS_SELECTOR, "button[class='btn-primary'][type='button']", "Done Button")
    elemDone = browser.find_element_by_css_selector("button[class='btn-primary'][type='button']")
    elemDone.click()

    browser.switch_to.default_content()
    time.sleep(20)

我尝试使用 switch_to.frame(framename) 从第 4 个父帧向后切换到第 1 个父帧，然后使用 switch_to.default_content() 仅抛出 NoSuchFrameException .我想要的只是能够退出框架，就像我进入它们一样，无需更改/删除窗口中的任何内容并返回顶级 HTML。

Answer 1

尝试查找所有 iframe 并切换到您需要的那个。

// find all your iframes
List<WebElement> iframes = driver.findElements(By.xpath("//iframe"));
        // print your number of frames
        System.out.println(iframes.size());

        // you can reach each frame on your site
        for (WebElement iframe : iframes) {

            // switch to every frame
            driver.switchTo().frame(iframe);

            // now within the frame you can navigate like you are used to

        }

Answer 2

作为driver.switch_to.default_content() 的替代品，您还可以使用：

browser.switch_to.parent_frame()

更新

由于您仍然面临同样的问题，更好的方法是等待 elemDone.click() 步骤完成（JavaScript / Ajax 调用）可以为一些visibility_of_element_located()诱导WebDriverWait如下：

elemDone = browser.find_element_by_css_selector("button[class='btn-primary'][type='button']")
elemDone.click()
WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "css_of_an_element_which_gets_displayed_after_the_click")))
browser.switch_to.default_content()
# as an alternative use `switch_to.parent_frame()`
# browser.switch_to.parent_frame()

注意：出于调试目的，您可以将 WebDriverWait 替换为 time.sleep(5)
