How to get link URL on onClick in a QWebView?

问题

How do I get a link's URL when clicking on the link?

If I have a link in the A tag, it's simple: just connect linkClicked(const QUrl&) signal to specific slot.

But if I have a table with an "onClick" event on its cell (generated html: "<td onClick=\"window.location.href='" + link_ + "';\" ......blahblahblah"), it's not working. Why?

回答1:

As it's name suggests, the linkClicked signal is only emitted whenever a link is activated.

But you can intercept all navigation requests by reimplementing acceptNavigationRequest:

class WebPage(QtWebKit.QWebPage):
    def __init__(self, parent=None):
        super(WebPage, self).__init__(parent)
        self.setLinkDelegationPolicy(QtWebKit.QWebPage.DelegateExternalLinks)

    def acceptNavigationRequest(self, frame, request, type):
        print('Navigation Request:', request.url())
        return False

...

webview.setPage(WebPage())

But note that all navigation requests are passed through this method, so your implementation should return True whenever it does not intend to handle the request.
