Several methods of QtWebkit operating web pages

One, C++ implementation

[cpp]  view plain copy

1. QWebFrame* frame = webView()->page()->currentFrame();  
2. if (frame!=NULL){  
3.     QWebElementCollection collection1 = frame->findAllElements(“input[name=submit]”);  
4.     foreach (QWebElement element, collection1){  
5.   
6.         QPoint poss(element.geometry().center());  
7.         QPoint pos = this->topLevelWidget()->mapToGlobal(QPoint(0,0));  
8.         QMouseEvent event0(QEvent::MouseButtonPress, pos, Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);  
9.         QApplication::sendEvent(webView->page(), &event0);  
10.         QMouseEvent event1(QEvent::MouseButtonRelease, pos, Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);  
11.         QApplication::sendEvent(webView->page(), &event1);  
12.     }  
13. }  

This method is effective for pure HTML webpages, but webpages that implement the submission function by javascript may not be effective.

Two, javascript implementation

transfer

[cpp]  view plain copy

1. evaluateJavaScript(code);  

Three, the combination of the two to achieve

[cpp]  view plain copy

1. QWebFrame* frame = webView()->page()->currentFrame();  
2. if (frame!=NULL) {  
3.     QWebElementCollection collection1 = frame->findAllElements(“input[name=submit]”);  
4.     foreach (QWebElement element, collection1){  
5.         element.evaluateJavaScript("this.click();");  
6.     }  
7. }
