有没有一种方法可以首先在主窗口中搜索网络元素(如果找不到),然后开始在iframe中搜索?

selenium

要求:默认情况下,在主窗口上搜索网络元素,如果找到则执行操作,否则在iframe中搜索网络元素并执行所需的操作

selenium3.141

'''
WebElement el = driver.findElement(By.xpath("//*[contains(text(),'here')]"));
    boolean displayFlag = el.isDisplayed();
    if(displayFlag == true)
    {
    sysout("element available in main window")  
    el.click();
    }
    else 
    {
      for(int f=0;f<10;f++)
      {
          sysout("element available in frameset")  
          switchToFrame(frameName[f]);
          el.click();
          System.out.println("Webelement not displayed");
      }
    }
'''

我的脚本本身在第一行失败。它正在尝试在主窗口中查找元素,但该元素实际上在iframe中可用。

但要求是先在主窗口中搜索,然后再导航至iframe。如何处理这种用例?

有什么建议会有所帮助吗?谢谢。

是的,如果主窗口中不存在该元素,则可以编写一个循环遍历所有iframe。 Java实现:

 if (driver.findElements(By.xpath("xpath goes here").size()==0){
     int size = driver.findElements(By.tagName("iframe")).size();
     for(int iFrameCounter=0; iFrameCounter<=size; iFrameCounter++){
        driver.switchTo().frame(iFrameCounter);
        if (driver.findElements(By.xpath("xpath goes here").size()>0){
            System.out.println("found the element in iframe:" + Integer.toString(iFrameCounter));
            // perform the actions on element here
        }
        driver.switchTo().defaultContent();
    }
 }

Python实现

# switching to parent window - added this to make sure always we check on the parent window first
driver.switch_to.default_content()

# check if the elment present in the parent window
if (len(driver.finds_element_by_xpath("xpath goes here"))==0):
    # get the number of iframes
    iframes = driver.find_elements_by_tag_name("iframe")
    # iterate through all iframes to find out which iframe the required element
    for iFrameNumber in iframes:
        # switching to iframe (based on counter)
        driver.switch_to.frame(iFrameNumber+1)
        # check if the element present in the iframe
        if len(driver.finds_element_by_xpath("xpath goes here")) > 0:
            print("found element in iframe :" + str(iFrameNumber+1))
            # perform the operation here
        driver.switch_to.default_content()
