PYQT操作JS并且截图事例

如何安装PYQT，可以查看我的上一篇文章：http://www.cnblogs.com/liqiu/p/3361948.html

然后运行下面的带有JS程序的Python脚本即可：

#-*- coding:utf-8 -*-
import sys
import os.path
import time
from PyQt4 import QtGui,QtCore,QtWebKit

class PageShotter(QtGui.QWidget):
    def __init__(self,url,parent=None):
        QtGui.QWidget.__init__(self,parent)
        self.url = url
    def shot(self):
        webView = QtWebKit.QWebView(self)
        self.webPage = webView.page()
        webView.load(QtCore.QUrl(self.url))
        self.connect(webView,QtCore.SIGNAL("loadFinished(bool)"),self.savePage)
    def savePage(self,finished):
        #print finished
        if finished:
            print u"开始截图！"
            self.webPage.mainFrame().evaluateJavaScript("document.getElementById('kw').value='liqiu';");
            size = self.webPage.mainFrame().contentsSize()
            print u"页面宽：%d，页面高：%d" % (size.width(),size.height())
            self.resize(size.width(),size.height())
            self.webPage.setViewportSize(QtCore.QSize(size.width()+16,size.height()))
            img = QtGui.QImage(size, QtGui.QImage.Format_ARGB32)
            painter = QtGui.QPainter(img)
            self.webPage.mainFrame().render(painter)
            painter.end()
            fileName= "shot.png";
            if img.save(fileName):
                filePath = os.path.join(os.path.dirname(__file__), fileName)
                print u"截图完毕：%s" % filePath
            else:
                print u"截图失败";
        else:
            print u"网页加载失败！"
        self.close()
if __name__=="__main__":
    app = QtGui.QApplication(sys.argv)
    shotter = PageShotter("http://www.baidu.com/")
    shotter.shot()
    sys.exit(app.exec_())

这里面可能需要使用JS，修改页面的内容，上面红色的部分已经标出。

结果：
