</a>

如何在QWebKit(特别是QWebPage)中链接(href).

how to follow a link (href) in QWebKit (specifically QWebPage).

请注意，这是一个链接的图像.
我无法通过模拟鼠标单击来做到这一点(即使我也无法做到)，因为我不使用QWebView，因此我无法呈现页面.

Please notice that it's an image that is linked.
I can't do it (and I don't want to even if I could) by simulating a mouse click as I don't use QWebView thus I don't have the page rendered.

推荐答案

假定链接的QWebElement位于名为"link"(通过findFirst或其他方式定位)的变量中:

Assuming you have the link's QWebElement in a variable called "link" (located through findFirst or whatever):

link.evaluateJavaScript("var evObj = document.createEvent('MouseEvents'); evObj.initEvent('click'，true，true); this.dispatchEvent(evObj);")

link.evaluateJavaScript("var evObj = document.createEvent('MouseEvents');evObj.initEvent( 'click', true, true );this.dispatchEvent(evObj);")

(这是在Python中，但是重要的是Javascript.是的，这是在模拟鼠标单击，但是由于它不使用坐标，因此可以在未渲染的QWebPage上正常工作.)

(This is in Python, but it is the Javascript that matters. And yes, this is simulating a mouse click, but since it does not use coordinates, it works fine with an unrendered QWebPage.)
