（相关的XPATH教程具体可以参考W3C的教程进行学习）
　　Using JavaScript
　　这么这是两个例子，例子一需要提前加载jqury的支持
　　element=driver.execute_script("return $('.cheese')[0]")
　　labels=driver.find_elements_by_tag_name("label")inputs=driver.execute_script("var labels = arguments[0]， inputs = []; for (var i=0; i < labels.length; i++){"+"inputs.push(document.getElementById(labels[i].getAttribute('for'))); } return inputs;"，labels)
　　User Input - Filling In Forms
　　select=driver.find_element_by_tag_name("select")allOptions=select.find_elements_by_tag_name("option")foroptioninallOptions:print"Value is: "+option.get_attribute("value")option.click()
　　有些选择提取的元素是需要进行筛选的如
　　# available since 2.12fromselenium.webdriver.support.uiimportSelectselect=Select(driver.find_element_by_tag_name("select"))select.deselect_all()select.select_by_visible_text("Edam")
　　那么这些form进行如何提交呢？
　　driver.find_element_by_id("submit").click()
　　element.submit()
　　Moving Between Windows and Frames
　　<a href="somewhere.html"target="windowName">Click here to open a new window</a>
　　driver.switch_to_window("windowName")
　　driver.switch_to_frame("frameName")
　　driver.switch_to_frame("frameName.0.child")
　　切换一些弹出来的比如登录框等
　　Popup Dialogs
　　这类的有alerts， confirms， and prompts等
　　alert=driver.switch_to_alert()
　　返回的是一个弹窗的窗体对象
　　Cookies
　　# Go to the correct domaindriver.get("http://www.example.com")# Now set the cookie. Here's one for the entire domain# the cookie name here is 'key' and its value is 'value'driver.add_cookie({'name':'key'，'value':'value'，'path':'/'})# additional keys that can be passed in are:# 'domain' -> String，# 'secure' -> Boolean，# 'expiry' -> Milliseconds since the Epoch it should expire.# And now output all the available cookies for the current URLforcookieindriver.get_cookies():print"%s -> %s"%(cookie['name']，cookie['value'])# You can delete cookies in 2 ways# By namedriver.delete_cookie("CookieName")# Or all of themdriver.delete_all_cookies()
　　Changing the User Agent
　　profile=webdriver.FirefoxProfile()profile.set_preference("general.useragent.override"，"some UA string")driver=webdriver.Firefox(profile)
　　Drag And Drop
