title: what's the difference between webView.load(QUrl) and QNetworkAccessManager.get(Qurl) in QT?
body: <p>UPDATE:I use javaScriptConsoleMessage and got a message on there sites:</p>
  
  <pre><code>Can't find variable: jQuery
  </code></pre>
  
  <p>I use PyQt on my project。
  Today I want to change the web access way from webView.load(QUrl) to QNetworkAccessManager.get(Qurl)，because webView.load(QUrl) can't use async.</p>
  
  <p>just like below：</p>
  
  <p>before:</p>
  
  <pre><code> self.webView.load(QUrl(input_url))
  </code></pre>
  
  <p>after:</p>
  
  <pre><code>AM = QNetworkAccessManager(parent=self)
  self.net_reply= AM.get(net_requests)
  AM.finished.connect(self.setweb)
  
  def setweb(self, netreply):
      replyArray = netreply.readAll()
      self.qwebView.page().mainFrame().setContent(replyArray )
  </code></pre>
  
  <p>After changed,It work well in most websites, but in some websites(eg, <a href="http://www.china.com.cn" rel="nofollow">http://www.china.com.cn</a>) the view is not so good ,just like they dont have a css style.How can I change the code to get the right view like webView.load(QUrl)? </p>
