在我的程序中循环时，我试图切换到的帧在第一个循环后发生变化，然后我无法访问它，而第二个循环失败。帧名称每次都会更改3倍，这是我最初切换帧的示例：
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-1']/iframe"))
Next frame
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-4']/iframe"))
Next frame
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-7']/iframe"))
如何在每个帧中再添加3个，以便在第一个循环之后在正确的帧中结束？
这是元素（我更改了SRC的时间很长）：
<iframe width="100%" height="100%" scrolling="auto" frameborder="0" src="/website/impactingActivities.do.dialogId=ui-id-1" onload="top.hideLoadingDiv('ui-id-1','ui-id-1');top.rightclickdisable('ui-id-1')" style="visibility: visible;"></iframe>

答案 0 :(得分：2)
如果您打算循环遍历所有iframes，我将首先使用一个更通用的选择器来获取所有这些元素，然后在每个循环中使用for。
# grab all of your iframes at once if you have access to them
iframeElements = driver.find_elements_by_xpath("//*[contains(@id, 'ui-id']/iframe")
for iframe in iframeElements:
driver.switch_to.frame(iframe)
一种潜在的方法，当最初无法如评论中所述获得它们时，您可以跟踪增量（始终为3）和乘数（每次增加1）。 ：
# outside of loop
def get_iframe_id(multiplier):
delta = 3
return str(1 + delta * multiplier)
mult = 0
#start of for or where loop
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-" + get_iframe_id(mult) + "']/iframe"))
# Next frame
mult += 1
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-" + get_iframe_id(mult) + "']/iframe"))
# Next frame
mult +=1
driver.switch_to.frame(driver.find_element_by_xpath("//*[@id = 'ui-id-" + get_iframe_id(mult) + "']/iframe"))
mult += 1
# Whatever you do to check for breaking out of loop
# End of loop
以下是乘数每次增加1时发生的情况的数学公式：
id = 1 + delta * multiplier
1 = 1 + 3 * 0
4 = 1 + 3 * 1
7 = 1 + 3 * 2
10 = 1 + 3 * 3
13 = 1 + 3 * 4
16 = 1 + 3 * 5
etc...
