我尝试使用一个唯一的class_name,它只在页面完全加载后出现,但是对于其他一些reaseon,它会在它出现在屏幕上之前出现
try:
WebDriverWait(self.browser, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, 'selo-fechado'))
except:
pass
除了time.sleep(4)之外,我还能做什么才能等到页面加载?

以下是我发现的最佳和最可靠的解决方案:
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtWebKit import *
from lxml import html
#Take this class for granted.Just use result of rendering.
class Render(QWebPage):
def __init__(self, url):
self.app = QApplication(sys.argv)
QWebPage.__init__(self)
self.loadFinished.connect(self._loadFinished)
self.mainFrame().load(QUrl(url))
self.app.exec_()
def _loadFinished(self, result):
self.frame = self.mainFrame()
self.app.quit()
url = 'http://pycoders.com/archive/'
r = Render(url)
result = r.frame.toHtml()
#This step is important.Converting QString to Ascii for lxml to process
archive_links = html.fromstring(str(result.toAscii()))
print archive_links
