python3.5+selenium3.4自动化测试5_frame中的对象

这篇主要讲定位frame中的对象，经常会遇到使用firebug定位到某个元素，但运行的时候却找不到元素，很多情况是因为在web页面中经常有嵌套其他页面，所以一般我们需要在firebug的html页面中搜索一下frame或iframe

1.这边主要通过driver.switch_to.frame(“mainscreen”)这句话来切入到id=”mainscreen”的嵌套中，当然也可以用name，tag_name,只要在括号中填入对应的即可，通过这句话，切入到嵌套中之后，就可以按之前用firebug定位到的元素进行编写即可

2.driver.switch_to.default_content()这句话是退出原来的嵌套回到原来的主文档，就可以在原来的主文档操作，所以这边主要用firebug查看下，到底你对应的元素是在哪个iframe中

3.driver.switch_to.parent_frame()可以看到parent这个词，就是父的意思，主要遇到的是多个嵌套的问题，可能嵌套里面还有一个嵌套，比如

<html>
<iframe id="mainscreenA">
<iframe id="mainscreenB" / >
</iframe>
</html>

driver.switch_to.frame("mainscreenA")#进入A
driver.switch_to.frame("mainscreenB")#进入B
driver.switch_to.parent_frame()  #退回A，如果当前是主文档，则无效果

4.这个代码中还有一个获取图片的名字，其实在很多爬虫图片中经常会爬取图片名，这边主要用到

img_url=driver.find_element_by_xpath(".//*[@id='table_Ext_list']/tbody/tr[2]/td[1]/img").get_attribute('src')

img_name=img_url.split('/')[4]
